你好这位朋友,加拿大的大平原地带主要横跨三个省份,合称为Canadian Prairies。我在Wikipedia和其他网站上帮你找了相关资料,并进行了简要的修改和整合成一篇简介如下。最后的一张图片里标明了大平原的在地图上的涵盖地域范围。
The Canadian Prairies is a region in western Canada, which may correspond to several different definitions, natural or political. Notably, the Prairie provinces or simply the Prairies comprise the provinces of Alberta, Saskatchewan, and Manitoba, as they are partially covered by prairie (grasslands). In a more restricted sense, the term may also refer only to the areas of those provinces covered by prairie. Prairie also covers portions of northeastern British Columbia, though that province is typically not included in the region in a political sense.The word prairie usually refers to a type of grassland, and true prairies occur only in the southern reaches of Alberta and Saskatchewan. Contrasted to this are other biomes such as the boreal forest taking up the majority of the Prairie Provinces, or the aspen parkland.
However "the prairies" may also refer to all of the Interior Plains region within Canada, in contrast with the Rocky Mountains and Canadian Shield, and is a continuation of the Great Plains region of the United States.
It may also refer to all of the farmland in the provinces of Alberta, Saskatchewan, and Manitoba, a definition based on human use, which includes all of the aspen parkland biome.
According to the Köppen climate classification the Canadian prairies generally experience dry semi-arid climates (Köppen Bsk) in the brown soil regions, and somewhat dry Humid Continental climates (Köppen Dfb) in the outer dark brown and black soil areas. The Canadian prairies typically experience about 12 to 15 inches (300 to 380 mm) of annual precipitation in the semi-arid areas while they experience 16 to 20 inches (410 to 510 mm) in the continental regions. Manitoba is the most humid of the three prairie provinces.

地形的主要特征 1.地形多种多样 在中国辽阔的大地上,有雄伟的高原、起伏的山岭、广阔的平原、低缓的丘陵,还有四周群山环抱、中间低平的大小盆地。陆地上的5种基本地形类型,中国均有分布,这为中国工农业的发展提供了多种多样的条件。 2.山区面积广大通常人们把山地、丘陵和比较崎岖的高原称为山区。中国山区面积占全国总面积的2/3,这是中国地形的又一显著特征。山区面积广大,给交通运输和农业发展带来一定困难,但山区可提供林产、矿产、水能和旅游资源,为改变山区面貌、发展山区经济提供了资源保证。 3.地势西高东低 呈阶梯状分布地势是地表高低起伏的总趋势。中国地势西高东低,大致呈阶梯状分布。
