中文摘要	为揭示锡林郭勒草地土壤养分状况,利用20062011年土壤主要养分测定资料,进行统计分析并应用主成分原理对土壤养分综合评价。结果表明,锡林郭勒草地土壤主要养分有机质、全氮、全磷、全钾含量分别为22.444、1.047、0.371、23.564 g/kg,各养分含量变异程度除全钾为弱变异,其他均为中等变异。丰缺状况有机质、全氮中等(3级),全磷含量很缺乏(5级),全钾含量丰富(2级),土壤养分含量处于中等水平。区域综合评价土壤养分锡林浩特市最高,二连浩特市最低。草甸草原最高,典型草原次之,荒漠化草原最低。为推进退耕还林还草工程及发展畜牧业生产,提高草地生产力与合理利用草地资源提供理论依据。
英文摘要	To reveal the soil nutrient contents of Xilin Gol Prairie, practical data on the main soil nutrient contents from 2006 to 2011 were statistically analyzed and integrated evaluation of soil nutrients was finished on principal component theory. The result showed that the soil nutrients of Xilin Gol Grassland were mainly organic matter, the content of total N, total P and total K were 22.444 g/kg, 1.047 g/kg, 0.371 g/kg and 23 g/kg respectively, and the degree of variation of each other was moderate except total Ks little variability. The contents of soil nutrients were in the moderate level, in which contents of organic matter and total N were in the moderate level (Ⅲ), content of total P was low level (Ⅴ), and the content of was much high level (Ⅱ). The regional integrated evaluation showing that the soil nutrients of Xilinhot was the highest level and Erenhot was the lowest level; the meadow steppe was the highest following by the typical grassland and the grassland as desertification was the lowest, provided a theoretical basis for promoting the restoration of farmland to forest and pasture and the development of animal husbandry and improving the grassland productivity and reasonable utilization of grassland resources.
