Distribution Only the upper reaches of the Yangtze River to China's Qinghai-Tibet Plateau deep alpine transition zone, including Qinling, Minshan, Qionglai Mountain, size and the size of Liangshan, etc. Ridge Mountains. Located in the south of the Qinling Mountains, is distributed mainly in Foping County, the general distribution of the Yangxian County, only a small amount of the distribution of county Taibai, Ningshan, weeks, etc.. Minshan of Gansu County, except for general distribution, the remaining are located in Sichuan. Sichuan mainly distributed in the county in Pingwu, Sichuan and Green Beichuan three counties, the general distribution of a Nanping, Songpan, Mau Timor, and other counties, a small amount of the distribution of county County, Mianzhu, Peng County, Shifang, and Dujiangyan City. Qionglai mountains are mainly distributed in Baoxing County, Wenchuan and Tianquan, a general distribution of Dayi and Lushan County, the only county with a small amount of Qionglai,崇庆, Kangding, Luding, etc.. Size of Mill Hongya and except for general distribution Mianning County, only a small amount of the distribution of Yingjing County, asbestos, Hanyuan, Kowloon. Size Liangshan addition Mabian, Meigu and the West have a certain number, only a small number of counties have甘洛, Ebian and Leibo, etc. (Pan Shi, 1988; Malaysian Yao, 1988; HU Jin-chu, 1985 ). Giant panda habitat and migratory habits of the mountains upstream of the Yangtze River deep mountains for the southeast monsoon wind surface, climate温凉humid, humidity often more than 80 percent, so they are a - hi moist animals. Their activities in the regional multi-Au ditch,山腹depression, valley terraces, usually in the 20 ° below the gentle slope terrain. These local soil hypertrophy, forest Maunsell, niitakayamensis grew well constitute a relatively stable temperature, good concealment conditions, food and water resources are abundant good food base. Life Habits In addition to estrus, often live alone Migratory life, and day and night trip. Nest domain area of 3.9-6.4 km2 volatile, and individual overlapping jurisdiction between the phenomenon of the nest, the nest of male domain slightly larger than female. Estrogen-only activities most of the time in 30 to 40 hectares of nuclear area, the female bodies in the nuclear domain do not overlap (HU Jin-chu, 1985). Food is the main mountain, subalpine about 50 kinds of bamboo, and even potable other plants, and even animal carcasses. Japanese appetite great day went to the drinking water springs or streams. Sexual maturity is 6.5-7.5, more than April estrus. In general was early September in the old trees in the farrowing nest hole, each child prolific 1 Aberdeen, occasionally producing 2 Aberdeen. With the baby after the mother left the mother of 18 months. The wild male and female sex ratio is about 1:1 (beam齐慧, 1993; Wen Wei Fu, 1994). To risk factors 1, forest harvesting. Giant panda habitat area to the annual harvest of at least 10,000 hectares. Each of their habitat to about 2.5 km2 at the rate of disappearance (Kleiman et al, 1991). Nearly 30 years ago, Shaanxi, Gansu, and Sichuan Provinces distribution panda population in the area doubled to over 43 million people, large-scale logging enterprises since 1950-1985, a total of 27 (excluding县属logging Field), the harvesting of forest area to verify for more than 420,000 hectares, with an average annual logging area of over 20,000 hectares, resulting in habitat by the early 1970's 31,450 km2, and after 15 years, has dropped to 13921.52 km2 and reduce area of 17528.48 km2, accounting for the original habitat the 56 percent and caused six cutting the district Panda disappeared, 10 cutting the region only a handful of surviving panda, the sharp decline in population size (HU Jin-chu, 1993); 2, capturing too much. As in Wenchuan County grassland before liberation, Britain, the United States and other Western countries, then catch vivo acquisition of over 20 only (those killed outside), where the giant panda population which, to date more than 50 years, the number remains low, yet to return. Again宝兴县from 1963 to date, only one county to capture pandas reached 113 and above. From the mid-1950s, the giant pandas from the wild catch has been over 240 to display at home and abroad, which is concentrated in Baoxing 110 MS only, Ping Wu, more than 60 only, resulting in the two county population structure was damaged, a significant number of decreased (HU Jin-chu, 1993). According panda life table analysis, which a generation would take about 12 years, population growth is slow, such as large catch, even in the protection of a good situation, also take decades to restore; 3, and in recent years, the giant panda poaching smuggling hides were still occur from time to time; 4, the giant panda population distribution in more than 25 island isolated habitats. These isolated habitat area the size of 205 km2 (30-2384km range), the majority of whom (67%) of the area less than 350 km2 (Kleiman et al, 1991). This population of isolation and division is a long-term threat to its population of important factors, small groups of inbred recession phenomenon will reduce fecundity, larval survival and disease resistance. Ultimately "island" members will disappear. According to Pan, and others (1988) on the Qinling panda population genetic analysis, there are more than 200 giant pandas, can constitute a about 90 breeding groups, their generation hybrid rate decline rate was 0.54%, after 12 and after 140 years later, every member will have 1 / 8 of the same gene, or table (Church) brothers and sisters of the relationship; 5, due to human activities extend the scope of the giant pandas were forced to retreat to the Peak, a very simple bamboo species meet with a bamboo flowering, no room to maneuver, only 1975 Minshan region niitakayamensis flowering, the death of 138 over 1980's Qionglai Hill flowering cold niitakayamensis large area, the giant pandas disaster found the bodies 108, died 33 for a total 141 (HU Jin-chu, 1993); 6, in panda habitats exist without permission from the government of mineral development, pollution and the miners, tree felling and hunting is one of the threat (Kleiman et al, 1991). Natural history Giant panda is a unique black and white coat color with the lively animals. Its Latin name: Ailuropodamelanoleuca, it refers to the black and white appearance. The giant panda species is a controversial issue of a century: whether it belongs to Bear Branch, or as close as the Red Panda raccoon Branch, or a separate species? Recent DNA analysis indicates that giant pandas belonging to Bear Branch, a representative of the early Bear Branch branch. Adult pandas about 120-190 cm and weighing 85 to 125 kilograms. Unique features include: large and flat molars, it's a developed carpal has become a "pseudo-thumb" is to adapt to fresh bamboo for the living. Bear with other six different categories, pandas and sun bears are not hibernating behavior. Food Properties Panda very special recipes, including the almost alpine region can be found in the various bamboo, the pandas also occasionally carnivorous (usually animal body). Panda unique characteristics of the food it was the local people called "Bamboo Bear." Bamboo lack of nutrition, survival can only provide the basic nutritional requirements, the pandas adapt to a gradual evolution of the characteristics of this recipe. In the wild, in addition to sleep or short-range activities, daily feeding time for the giant pandas as long as 14 hours. A giant panda eating 12-38 kilograms of food per day, close to its body weight of 40%. Panda likes to eat bamboo most nutritious, containing cellulose least part of that Soft, shoots, and bamboo shoots. Giant panda habitat usually have at least two kinds of bamboo. When a bamboo flowering at the time of death (bamboo every 30-120 years will periodically flowering death), the giant pandas can turn feeding other bamboo. However, habitat fragmentation of the increased status within the habitat of bamboo may be only one, when such deaths bamboo, the pandas will be in the region face the threat of starvation. Captive and social behavior "Breeding difficulties" as news headlines to describe the propagation of the giant pandas situation. However, the study shows that although the wild giant pandas in captivity live longer state, but the wild, breeding success rate higher. In the wild, adult pandas regardless雄雌are involved in reproduction. Several female can fight duality and the male mating, but will be looking for a male in a different period of estrus females. In spring mating season 3-5 month, usually no more than 2-4 days. Pregnancy is about five months. Wild occasional twin circumstances, but generally only female panda feeding a cub. Captive populations, the twin of more. Before childbirth, female individuals find empty holes in tree roots and the production. Such shelters in the vicinity, and to stay on for three months, with its generous hand carefully care cub. Giant panda cub born very small, usually only 100-200 grams, there are only female bear the weight of 1 / 900. Panda cubs in the past few days to a month after the birth, the mother panda baby will be left in tree holes or holes out foraging. Mother beast sometimes leave two days or even longer. This does not mean that it abandoned baby, but the process of bringing up baby part of it is natural. Baby in the 12 months or so begun to eat bamboo, but in the meantime, they are completely dependent on his mother. Wild baby mortality rate lower than the pen, about 40 percent (Pan, and others, are being published). Qinling region in the long-term study indicate that the giant panda breeding rate of about 0.654 baby / female / annual (Pan, and others, are produced), and North American natural population of brown bear some similar (Stringham1990). Giant pandas are living animals, each adult domain clear of the nest, the male domain of individual nests are usually large, close to 30 square kilometers, general and the number of female individual nest domain overlap. When the nest male giant pandas in the same meet with each other jurisdictions, such as the estrus period of female pandas in the surrounding, and they have a clear hierarchy, will lead to an even struggle. The advantage of the individual male and female mating a priority, but there are also opportunities for other males. Female individual in 3-4 at the age of sexual maturity, individual and 5-year-old male around. Young male individual in the position in the lower grades, 7-8 at the age of a chance mating. From the 4-year-old female individual to the 20-year-old, usually once every 2-3 with an annual output of Aberdeen. Although the only giant panda family structure exists only less than 18 months and the mother of the beast between the baby panda will be between sounds and smells through regular exchanges, if not in estrus. One-year-old giant panda baby in about weaning, and has been to 18 months and mother together about his mother again until pregnancy. If not pregnant mother beast, and the baby lives with his mother to two-year-old half, it drove them off when the mother. After independence, most of the baby in the mother's nearby residence, others, especially female, will be living away from the place of birth. Giant pandas need to conduct further research. Captive giant pandas can survive 30 or more, but the life span of wild giant pandas usually only about 20 years. History Fossils show that giant pandas ancestors appeared in 2-3 million years ago alluvial Ji early. Giant panda habitat in China had covered most of eastern and southern regions, the North of Beijing, the southern and south Vietnam in northern Myanmar (夏勒, 1993). Fossils are usually at an altitude of 500-700 meters in temperate or subtropical forest found. Giant panda habitat only in modern times and the tremendous changes occurred. Over the past few hundred years the Chinese occupation of the land and rapid population growth, many habitat disappeared. Previously, the giant panda had lived in low mountain valley, has now become settlements. Giant pandas only live in the bamboo can grow between elevation 1200-3400 meters. The current distribution The number of wild giant pandas in the end? This is a very difficult question to answer. Living in the high mountain areas on steep slopes of bamboo, the panda statistics become a very hard work. In the 1970s and 1980s have had two surveys, it is estimated that about 1,000 giant pandas field, this figure may be low. Panda regional distribution of the total 37 counties, if by the middle, and a small amount of the general three-tier division, the main producing counties each about 100 around the county, a total of seven counties; general production County each county about 50 more, a total of 11 This projection, the number of wild giant pandas more than 1,000 total only about 1, the number of captive about 100 AAAZPA Communique, 1993). Panda's net reproductive rate of 1.0672, slow population growth (Sichuan precious animal resources Investigation Team, 1977; Bifeng Chau, 1989). Panda Bear Branch family is the most rare, are also under the greatest threat to the survival of the mammals. Giant pandas live in the eastern edge of the Qinghai-Tibet Plateau in southwest China's temperate forests, bamboo is the main understory plants here. Giant panda habitat on six separate mountains: the Qinling Mountains of Shaanxi, Gansu and Sichuan Minshan Mountains, the Qionglai, Sichuan, and the size of the Liangshan Mountain Ridge. The 1980s survey of the habitat area of about 13,000 square kilometers (Reid and Gong 1999). According to the State Forestry Bureau in 2005 investigation report has now confirmed Qinling giant panda population will be identified as a new subspecies of giant pandas. The giant pandas in Qinling pandas in Sichuan and geographical separation of five years has been long on the Qinling pandas head shape than round. At present the number of Qinling pandas have 273. In the Qinling mountains, in black and white pandas found in the brown pandas. Classification dispute The classification status of giant pandas has been more controversial, is to giant panda Xiong ancestors evolved from the class before the panda. Now the internationally recognized it as a Bear Branch, the giant panda subfamily classification, is also gradually domestic recognition. Domestic traditional panda will be a separate classification for the giant panda Branch.

Protect Panda The giant panda is known as the national treasure of China. The panda was a kind of ordinary animal in China long ago. However, for some reasons, too many of them have been killed. So the number of them is falling quickly. At present people are taking an important measure to save pandas. People want to find a home for them, and recently, they have set up a nature park for them in Sichuan Province,which is called "Pandas' Home. "There pandas can enjoy their life happily. There is a bamboo forest near the Pandas' Home. So the pandas can find bamboos easily which they like to eat very much. Because pandas are well protected now, the number of them is increasing every year. We hope that one day we will have enough pandas to set them free and let them live in the wild again. Pandas are good friends of man. Man should try to protect them and ]et them live in the way they like!

Let's save the panda is one of the most lovely. Animals on land, but these years, panda nurseries get Salles and stains. If we don't protect them. Pandas live in China. They are fat, but smart. Adult pandas are black and white. Bamboo is their favorite food. They must be protected because they are in great danger. Because of the bad environment, the situation is getting worse and worse, and they live in a very poor place.让我们拯救熊猫是最可爱的。陆地上的动物，但这些年来，熊猫保育院变得灰暗和污点。如果我们不保护他们。熊猫生活在中国。他们很胖，但很聪明。成年熊猫是黑白相间的。竹子是他们最喜欢的食物。他们必须受到保护，因为他们处于极大的危险之中。
