农业生态经济系统分区方法研究——以四川盆周山区为例

THE RESEARCH ON THE METHOD OF THE REGIONAL DIVISION OF AGRICULTURAL ECO-ECONOMIC SYSTEM ——TO THE MOUNTAIN AREAS AROUND SICHUAN BASIN

农业生态经济系统分区，涉及到自然、生态、经济、社会等多方面因素，边界具有很强的模糊性。运用模糊聚类方法与判别分析相结合，既能适应上述特点，又有效解决了独立样本的合理归类问题。利用主分量分析选取聚类指标，并以各指标对主分量的负荷和作用为依据确定其聚类时的权重。

The Regional Division of Agricultural Eco-economic System, which boundary is very fuzzy, deals with multiple factors of nuture, ecology, economy and society. Many methods of regionalization have been approached, but the Fuzzy Cluster Analysis is more suitable. In order to decide the classification of independent sample,the Multiple Differentiation Analysis was used. The Primary Component Analysis was applied to select cluster indexes and reduce the subject-ivity of selecting indexes. The clustering weight of every index was decided according to each index loading and effecting on the primary component.
