摘　　要：退耕还林工程涉及我国自然、经济和社会条件各不相同的广大区域 ,只有基于科学的综合区划 ,才能保证工程建设的圆满成功。根据我国退耕还林工作的实际需要 ,研究以退耕还林工程的整个工程区 2 5个省 (区、市 )1897个县 (市、区、旗 )为研究对象 ,引入Matlab等先进理论和技术 ,横跨自然、经济、社会科学 3大领域 ,共获取原始数据 6 0 0 0 0多个 ,采用以定量为主 ,适当结合定性的方法 ,实行定性分析与定量分析相结合 ,对退耕还林区划进行了系统研究。对于较高级别的分区 ,采用自上而下的、定性与定量相结合的分析方法。对于较低级别的分区 ,采用自下而上的、定量分析的方法 ,即以Matlab为平台 ,运用层次分析法和系统聚类分析法 (HCM )进行分区。建立了退耕还林类型区划体系 ,即大区 -区 -亚区 -小区 ,将退耕还林工程区区划为 4个大区、12个区、39个亚区。The Conversion of Farmland to Forests Programme (CFF) includes vast areas with natural, social and economic conditions that are extremely complicated.CFF relies on support of comprehensive regionalization.The study covers the entire programme area of CFF(25 provinces, autonomous regions and municipalities, 1,897 counties or county-level cities and districts),and uses methods of Matlab,AHP,HCM and others. Based on over 60,000 original data from science and economics, the comprehensive regionalization was studied. The study methods are mainly quantitative, properly combined with qualitative ones. For higher hierarchy regions, the analysis methods are from top to bottom, combined quantity with quality. For lower hierarchy, the quantitative methods are adopted from bottom to top. A four-level hierarchy was proposed for CFF,i.e., region, sub-region, compartment and sub-compartment. Accordingly, CFF comprises 4 regions, 12 sub-regions, 39 compartments, and 116 sub-compartments. The 4 regions are respectively regions of lower reaches of Yellow River and north and northeast of China, the region of middle and lower reaches of Yantze River and south of China, of upper reaches of Yantze River and southwest of China, and of upper and middle reaches of Yellow River and northwest of China. The 12 sub-regions are respectively the mountain and sandland subregion in northeast China, the sandland and plain subregion around Beijing and Tianjin, the mountain and hills subregion in Sichuan-Chongqing-Hubei-Hunan, the lower mountain and hills subregion in the middle and lower reaches of Yangtze River, the plateau subregion of Yunnan-Guizhou, the mountain and hills subregion of Hainan-Guangxi, the high mountain and deep valley subregion in southwest China, the plateau subregion of Qingzang, the Loess Plateau subregion, the arid and desert subregion in Xinjiang, the plateau subregion in the source of Yellow River, and the desert subregion in Gansu and Inner Mongolia Plateau.
