摘要
本文根据省级生态农业建设与发展的需要，按照系统工程的原理与方法，定性与定量分析相结合的原则，建立了分区指标体系，并应用层次分析法确定指标权系数，然后选择了星座图聚类、判别分析与多维灰色评估３种数学模型，对山西生态农业环境进行了地区分类，大大增强了区划的科学性、准确性与实用性，取得了较好的效果，为宏观指导山西省生态农业的建设与发展提供了可靠的科学依据。
To meet the need for eco-agricultural construction and development,based on the princi-ples and methods of system engineering,and a combined qualitative analysis,an evoluationindicator system for eco-agricultural regionalization was given, and its weights were decidedwith AHP in this paper. Eco-agriculture regionalization of Shanxi province was made by ap-plying star cluster, discriminatory analysis and multidimensional evaluation. And the resultswas good and objective,and provided a scientific base for construction,development andmacroscopic guide to Shanxi eco-agriculture.
