中文摘要	为分析不同等级石漠化土壤侵蚀特征,以典型喀斯特区贵州关岭县为研究对象,以ZY-3影像为数据源,综合运用3S技术,非喀斯特区根据《岩溶地区水土流失综合治理技术标准》标准,喀斯特区根据《喀斯特地区土壤侵蚀综合治理技术》中石漠化与土壤侵蚀等级划分标准,解译出关岭县2015年土壤侵蚀与石漠化图,分析了不同等级石漠化区土壤侵蚀特征。结果表明:关岭县不同等级石漠化区的土壤侵蚀特征存在一定的规律,关岭县喀斯特区土壤侵蚀发生率比非喀斯特区低9.4个百分点,非石漠化区土壤侵蚀发生率略低于石漠化区,严重石漠化区土壤侵蚀发生率低于石漠化等级轻的区域。关岭县石漠化与土壤侵蚀区域分布及强度并不一致,在土壤侵蚀治理过程中应加强石漠化程度较弱区域的治理,同时更需要加强还未发生石漠化区域土壤侵蚀的防治。
英文摘要	In order to analyze the characteristics of soil erosion in different grades of rocky desertification area, taking the typical karst area Guanling County of Guizhou Province as the research object,according to the classification of standard for classification and gradation of soil erosion’and techniques standard for comprehensive control of soil erosion and water loss in karst region’,we used ZY-3 remote image as the data source,made the soil erosion and rocky desertification map in Guanling County in 2015 by comprehensive using the3S’technology.We analyzed the characteristics of soil erosion in different rocky desertification areas.The results showed that the characteristics of soil erosion in different grades of rocky desertification areas in Guanling county had certain regularity,soil and water loss rate of GuanLing karst area was 9.4% lower than in non-karst area,and soil and water loss rate in non-rocky desertification area was slightly lower than rocky desertification area,high grade rocky desertification area was lower than low grade rocky desertification area also.The regional distribution and intensity of rocky desertification and soil erosion in Guanling County were not consistent.In the process of comprehensive control of soil erosion,Guanling County should strengthen the management of lower level rocky desertification area,at the same time,it is necessary to strengthen the prevention of soil erosion in non-rocky desertification area.
