摘　　要：为了筛选出强度水土流失区理想的生物治理模式,为南方水土流失区治理提供植被恢复"范本",通过对福建长汀强度水土流失区4种不同生物治理模式的群落调查、物种多样性和土壤理化性质测定,采用灰色关联分析方法进行不同治理模式恢复效果的评价。结果表明:不同生物治理模式恢复效果均比对照好,可改良土壤结构,增加土壤蓄水保肥功能,提高土壤有机质和养分含量,丰富植被物种种类和数量。不同模式恢复效果不同,灰色关联序为:乔灌草混交模式(0.934)>经济林+封育模式(0.794)>灌木+草本模式(0.487)>灌木模式(0.484)>对照(0.337),其中乔灌草混交模式、经济林+封育模式的改良土壤肥力作用显著,植被物种多样性高,治理恢复效果好,是南方强度水土流失区值得推广治理模式。In order to select an ideal biological governance model in intensity soil erosion area of Changting County and popularize the vegetation restoration model in southern China,the biological community of 4 different governance models in intensity soil erosion area of Changting County was investigated and the soil physical and chemical properties were determined.The restoration effects of 4 different governance models were evaluated by the grey relation analysis method.The result showed that：restoration effects of four governance models were better than the control treatment which improve soil structure,increase soil fertilizer and water holding capacity,increase the content of organic matter and nutrient,rich vegetation species.The restoration effects of 4 different governance models were in the grey relation sequence of the model of mixed trees,shrubs and herbs（0.934）the model of enclosure after planting economic forest（0.794）the model of mixed shrubs and herbs（0.487）the model of planting shrubs（0.484）CK（0.337）.The governance models of enclosure after planting economic tree species and the model of mixed trees,shrubs and herbs were optimization with high plant species richness and biodiversity index,and soil properties improving which were popularization models in intensity soil erosion area of southern China.
