甘肃省黄土丘陵沟壑区第三副区小流域综合治理模式研究

Study on Comprehensive Control Models of Small Watershed inthe Third Sub-Region of Hilly-Gullied Area of Loess Plateau

针对黄土高原水土流失综合治理中存在的问题，在分析和总结小流域综合治理的基础上，针对黄土高原丘陵区第三副区建立小流域综合治理模式，采用模糊聚类定量分析方法和定性方法划分为４个亚区。并对各亚区土地利用结构进行了合理的调整，提出了水土保持措施的配置模式，对不同类型区综合治理有一定的指导意义．

in accordence with existing problems of comprehe.nsive control for soil and water loss on loess plateau based on analysis .and summary of experience of comprehensive control of small watersheds, comprehensive control models in small watershed of the third sub-region of hillygully region on loess plateau have been established, and four sub-regions are identified, using methods of quantitative analysis of fuzzy-cluster qualitative analysis. And land use structure of every sub-region has been rationally adjusted and arrangement model of soil and water conservation measures was put forward. All this have guiding action for comprehensive control in different type regions
