江淮丘陵及下游平原区水保分区防治途径探讨

Discussion on partitioning of soil and water conservation in Yangtze-Huaihe River hills and downstream plain area

水土保持区划是全国水土保持规划的基础。江淮丘陵及下游平原区是全国水土保持区划中太湖流域任务片的重要二级区,在已有的全国水土保持一级、二级区划基础上,依据江淮丘陵及下游平原区自然、社会经济、水土流失概况,进一步提出了该区水土保持三级分区。分析了各三级区的基本情况,指出了各区存在的水土保持方面的主要问题以及水土流失防治途径。研究成果可为平原区水土保持工作提供科学依据。

Partitioning of soil and water conservation is a foundation for strategy making and project layout in the national soil and water conservation planning. The Yangtze - Huaihe River hills and its downstream plain area is a main second - grade district of Taihu Lake Basin in partitioning of the national soil and water conservation planning. Based on the existed first and second - grade district partitioning in national soil and water conservation planning, the third - grade district partitioning for Yangtze - Huaihe River hills and downstream plain area is proposed according to natural condition, social - economic status as well as soil erosion in the area. Moreover, the basic condition of each third- grade district is presented, and the encountered problems as well as countermeasures in soll and water conservation are discussed.
