摘要
我国地域广阔、自然和经济社会条件复杂,水土流失分布广、面积大、类型多样,区域水土流失预防和治理的需求存在差异,需要紧密结合国家、区域发展总体战略和布局要求,兼顾水土流失的分布及强度类型和水土流失防治的区域需求差异,科学合理制定可操作的全国水土保持区划方案。文章综合分析我国的自然、经济社会条件,明确全国水土保持区划总体思路,建立区划体系和指标体系,采用资料统计分析、实地调查等方法,将"自上而下"与"自下而上"相结合,提出区划成果,全国(不包括港澳台地区),共划分8个一级区、40个二级区、115个三级区,成果具有区划界线清晰、分区命名规则、区划手段先进等特点。主要应用于全国水土保持规划分区布局和项目布局,并对下级区划(分区)、区域水土保持功能和技术体系确定具有指导意义,将长期用于指导我国水土保持工作。
[Background]There are vast territory and complex natural conditions in China. Soil erosion area in China is large and its forms are various,and degrees and intensities in different regions are different. Unbalanced economic development leads to different exploitation,utilization,and protection needs of soil and water resources. Therefore,the different strategy,mode,standard of soil erosion control in the corresponding area, i. e., scientific and rational scheme of soil and water conservation regionalization in China,should be considered. [Methods] Soil and water conservation regionalization could be formulated while taking full account of regional differences in natural conditions and socioeconomic development,coupling with national and regional development strategies and the overall layout requirements,coordinating the soil and water conservation needs of the country and local,watershed and regional as well as among departments,and taking into account the natural properties of soil erosion and the socio-economic attributes of soil and water conservation. Thus,the results of regionalization are presented by comprehensively analyzing natural,economic and social conditions,identifying the general idea of soil and water conservation regionalization,building regionalization system and indicator system,using statistical analysis,field surveys and other methods,and combining both managements of ＂topdown＂and ＂down-up ＂. [Results] 8 first-grade regions,40 second-grade regions,115 third-grade regions are divided across the country（ not including Hong Kong,Macao and Taiwan regions）. The results of regionalization have clear boundaries,rules of region＇s name,advanced regionalization meansand so on. It is mainly used in the partition layout and project layout of soil and water conservation planning, and has guiding significance for the lower regionalization（ partition）, soil and water conservation function and technology systems in specific area. [Conclusions]Soil and water conservation regionalization in China is comprehensive department regionalization,based on soil geology,topography and other natural conditions, socio-economic conditions as well as soil erosion conditions, which scientifically determines the direction for soil erosion control and technological system in different partition,and is a long-term guide of soil and water conservation in China.
