中国水土保持区划方案初步研究

水土保持区划是水土保持规划的基础,可为生态环境建设和区域管理与发展提供科学的依据.简要回顾了相关区划工作,明确了水土保持区划的概念,结合我国水土流失等生态环境特点,提出了水土保持区划原则、指标体系和命名规则;通过构建全国水土保持区划协作平台和数据上报系统,结合我国已有相关水土保持研究成果,采用自上而下与自下而上的演绎归纳途径和定性与定量相结合的方法,构建了我国水土保持区划初步方案,将全国划分为8个一级区,41 个二级区,117 个三级区.

A primary study on scheme of soil and water conservation regionalization in China

Regionalization of soil and water conservation is the basis for the planning of soil and water conservation in China. It can provide scientific basis for constructing healthy ecological environments and regional management and development. It makes a brief review of related regionalization of study and makes clear the concept of regionalization of soil and water conservation. In this paper, based on synthetical analysis of the characteristics of ecological environments of China, the principles, indices and nomenclature of the regionalization of soil and water conservation are proposed. Through the construction of the regionalization of soil and water conservation collaboration platform and data reporting system, combined with the existing soil and water conservation research, this paper uses the top-down and bottom-up and the combination of qualitative and quantitative methods to build soil and water conservation regionalization preliminary scheme, with 8 regions, 41 subregions and 117 sections divided across the country.
