中文摘要	通过对滇东南石漠化山地不同植被恢复模式下土壤的理化性质进行定点观测和地力变化及水土流失状况的分析,结果表明:封山育林地土壤的肥力较佳,其次是耕地土壤,这是由于封山育林地土壤多年来进行封山育林,耕地土壤进行了平衡施肥;3年后人工林地土壤的理化性质有很大改善,土壤肥力有很大提高,这是退耕还林的结果;从水土流失状况来看,耕地是产流产沙、固体和液体养分流失最严重的类型,人工林地水土流失最低,说明退耕还林和封山育林有利于石漠化山地土壤肥力的改善和水土保持功能的提高。
英文摘要	A study on the physicochemical property and soil erosion of different vegetation patterns in Xichong county of southeastern Yunnan was conducted by ocean weather station observation.The results showed that the land capacity of closing hillsides soil is the highest and the land capacity of cultivation land is higher,which resulted by closing hillsides to facilitate afforestation for many years,and balance fertilizing of cultivation land.As returning land for farming to forestry,the physicochemical property and land capacity of soil has been greatly improved after three years.Cultivation land is the most severe type from water and soil erasion analysis,the planted forest lands are the smallest.Closing hillsides to facilitate afforestation and returning land for farming to forestry are good approaches of land capacity improvement and soil and water conservation in karst mountains desertification soil of southeastern Yunnan.
