摘要
根据江西省农业自然资源状况及省级生态农业建设与发展的需求,按照生态学和系统工程的原理与方法,定性与定量分析相结合的原则,建立了区划指标体系,并应用系统聚类法和判别分析法,对江西省生态农业环境进行了区域划分研究,并将其划分为5个生态农业区。这一区划结果大大增加了区划的科学性、准确性与实用性,并且取得了较好的区划效果,为宏观指导江西省生态农业的建设与发展提供了可靠的科学依据。
According to the agricultural situation of natural resources and the need for provincial eeo-agricultural construction and development, based on the principles and methods of ecology and system engineering, and combined qualitative analysis with quantitative analysis, an evaluation indicator system for eco-agricultural regionalization was set up, and by using system cluster method and discriminating analysis, the study on coo-agricultural region'alization was made. The results showed that there are five coo-agricultural regions in Jiangxi province and were good and objective, and provided a scientific base for construction, development and macroscopic guide to Jiangxi coo-agriculture.
