摘　　要：西南岩溶峰丛洼地由于其特殊的地质构造和长期的降雨淋溶作用,形成了独特的地表-地下双层空间结构,使得该地区水土流失具有隐蔽性、特殊性和复杂性。综合分析了岩溶峰丛洼地水土流失的机理,总结了水土流失预测模型和水土流失防治技术,指明了现有研究存在的不足,并展望了今后峰丛洼地水土保持研究工作的前景。强调进一步加强岩溶峰丛洼地水土流失的定量研究,深入揭示水土流失机理,构建岩溶区地表-地下二元结构的水土流失预测模型,研发水土流失生物工程协同防治技术,加强耐旱型植被构建与规模化建设,为岩溶区水土资源的高效利用、生态恢复、水土流失综合治理提供科学依据。The unique geological structure and long-term leaching of karst peak-cluster depression in southwestern China caused a typical surface-underground double-layer spatial structure,which induces soil and water losses with a characteristic of concealment,particularity,and complexity.This review analyzes and summarizes the influencing factors,mechanism,and governance technique of soil and water losses in the karst peakscluster depressions,suggests deficiencies in soil and water loss research,puts forward the future control and governance strategies and priority research areas of soil and water loss in China.Further studies should focus on the quantification of soil and water loss in the karst peaks-cluster depressions,enhance the insights on the mechanisms of soil and water loss,derive reliable prediction models,developing collaborative control and governance technologies with biological engineering,such as promoting the drought-tolerant vegetations in karst areas of China.
