| 摘 要： | 以贵州省修文县自然地理和社会经济数据为基础,通过地理信息系统等手段,探讨县级水土保持规划中生态清洁小流域的分类问题,提出了由小流域地形地貌类型、水资源功能定位、人类活动强度组成的县域生态清洁小流域三级分类系统。采用三级分类系统将修文县83个小流域级分为10个类型,分为山地水源低、中强度类,山地非水源低、中、高强度类,丘陵水源低、中强度类,丘陵非水源低、中、高强度类等10个类型。并在分类的基础上提出各类型生态清洁小流域建设目标及方向,旨在为县域生态清洁小流域的建设提供参考。

Classification of Eco-clean Minor Watershed in the Water and Soil Conservation at County Level:A Case Study in Xiuwen County of Guizhou Province |

| Abstract: | Based on natura1 geography and socia1 economic data of Xiuwen county of Guizhou province, using geographic information system and other methods, the c1assification of eco-c1ean minor watershed in the p1anning of soi1 and water conservation was discussed at county 1eve1, and three stage c1assification system of eco-c1ean minor watershed was proposed, which was composed of watershed topography type, functions of water resources and human activity intensity. With the three stage c1assification system, 83 sma11 watersheds in Xiuwen County were c1assified into ten types, they were the water sources of the mountainous region in which mankind's activity intensity was 1ow and medium, the non water sources of the mountainous region in which mankind's activity intensity was 1ow, medium and high, the water sources of the hi11y region in which mankind's activity intensity was 1ow and medium,and the non water sources of the h11y region in which mankind's activity intensity was 1ow, medium and high. And then, different construction goa1s for each types of watershed were defined, aiming to provide a reference for the county construction of eco-c1ean minor watershed. |
