中文摘要	采集了贵州西部喀斯特地区中度石漠化、强度石漠化和非石漠化区域的草地土壤，并对样品的有机质和各形态氮素含量进行分析测定。统计特征值比较表明；在强度石漠化区域，土壤有机质和各形态氮素含量的变化幅度最大，中度石漠化区域次之，非石漠化区域最小。方差分析显示：中度石漠化区域与非石漠化区域的酸水解性全氮含量差异性显著，氨基酸态氮含量差异性极显著，而不同石漠化区域土壤有机质和其它各形态氮素含量差异性均不显著。此外，根据研究过程中所遇到的情况，提出了当前石漠化研究厦待解决的一些科学问题。
英文摘要	Grassland soil samples were collected respectively in the areas without obvious rocky desertification, the moderate rocky desertification region and the intensive rocky desertification region of the western Karst district, Guizhou province. The contents of soil organic matter（SOM） and different forms nitrogen were analysed. The variety range of SOM and different forms nitrogen is the widest in the intensive rocky desertification region and it is the narrowest in the areas without obvious rocky desertification. Analysis of variance indicated that hydrolysable and anmio-acid N content was significant between the moderate rocky desertification region and the areas without obvious rocky desertification, SOM and the other form nitrogen content wasn＇t significant in different regions. Based on the problems which were encountered in the research process, it put forward some subjects which would be studied in the research of rocky desertification immediately.
