黄土高原生态经济分区的研究
张青峰, 吴发启
西北农林科技大学资源环境学院 杨凌 712100
摘要:  在概述生态经济分区现状的基础上, 提出了在黄土高原进行生态经济分区的重要意义。选取自然资源、社会经济等22个指标, 以行政县(区)为单元, 利用聚类分析、主成分分析和GIS相结合的分区方法, 把黄土高原划分为4个生态经济带即南部暖温带半湿润农林生态经济带(Ⅰ)、中部暖温带半湿润半干旱农林牧生态经济带(Ⅱ)、西北部温带半干旱农牧生态经济带(Ⅲ)、北部温带干旱半干旱农牧生态经济带(Ⅳ)和18个生态经济区。通过该研究的实践, 不仅可为后续有效布设黄土高原的生态经济项目提供参考, 而且可为较大尺度区域进行生态经济区划研究奠定理论基础。

Abstract:  This paper discussed the significance of eco-economic regionalization of the Loess Plateau as reported in existing literature. 22 indexes of natural ecological and socio-economic systems were covered, and administrative counties (districts) were considered as complete individual taxons. The Loess Plateau was devided into 4 eco-economic belts — southern warm-temperate semi- humid agroforestry (Ⅰ); central warm-temperate, semi-humid and semi-arid agroforestry & animal husbandry (Ⅱ); northwestern temperate semi-arid agro-stockbreeding (Ⅲ); and northern temperate arid and semi-arid agro-stockbreeding (Ⅳ) eco-economic bands via principal component analysis (PCA) and cluster analysis (CA) on GIS platform. These belts were further divided into 18 eco-economic regions. The discussion emphasizes regionalization and methodological framework for large areas like the Loess Plateau region. Such practice could be specialized supplement in developing appropriate regional eco-economic theory.
