摘　　要：探讨不同治理措施(林地采用等高草带、乔灌草、封禁等措施,园地采用隔坡梯田、水平梯田、梯田+竹节沟等措施)对植被恢复和土壤性质的影响,并对植物多样性和土壤性质进行了相关分析,结果表明:不同治理措施对植物多样性(丰富度指数、多样性指数、均匀度指数)和土壤性质都有较大影响。林地以林草+封禁措施效果最佳,其次是乔灌草措施;园地以隔坡梯田的综合效益最好,再次是水平梯田。在紫色土丘陵地区侵蚀地植被和土壤恢复时,以工程措施和林草措施并用为宜,如隔坡梯田+乔灌草模式。In order to explore relationships between vegetation restoration and soil chemical properties in purple-soil hilly region,this paper studies effects of different management measures,such as planting grasses,trees,shrubs and herbaceous plants and no human interference measure,and deals with the relationship between vegetation restoration patterns and chemical properties of the soil. The results show that different measures of vegetation diversity（ Richness index, Shannon-Wiener index and Evenness index） and soil properties have significant difference. The treatment without artificial interference gains the best effect in woodlands,followed by the planting pattern mixed trees,shrubs and herbs. In the garden,the best measure is terrace,which is separated by a belt of undisturbed land,followed by the level terrace. In purple-soil hilly region with serious erosion,as for the recovery of vegetation and soil,we would recommend the management with the combination of engineering measures and biological measures.
