三峡库区农业生态经济分区的研究

Study on the agroecological -economic regionalization in the Three Gorges reservoir area

选取 31个生态经济指标 ,以行政县 (区 )为单元 ,采用 ISOTATA模糊聚类分析方法 ,把三峡库区分为 4个农业生态经济区 ,即 主城区城郊丘陵菜旅花牧加生态经济区、 江万丘陵低山粮经果牧加生态经济区、 武秭中山低山果林粮牧特生态经济区、 兴宜低山中山丘陵林果牧粮生态经济区。通过对各区生态经济特征的分析 ,提出了其生态经济的发展方向和生态环境保护的策略 ,可为三峡库区农业可持续发展和生态环境保护提供理论依据。

According to 31 selected eco -economic indexes , taking administrative county (district)as the unit ,the paper divides the Three Gorges reservoir area into 4 agroecological -economic regions by the fuzzy cluster analysis method of ISOTATA , that is, Ⅰthe vegetable -tourism-flower-animal husbandry-processing eco-economic region in the hilly area of outskirts of the main city proper ,Ⅱthe grain-economic crop-fruit- animal husbandry- processing eco-economic region in the hilly and low mountainous areas between Jiangjin City and Wanzhou District, Ⅲ the fruit-forest- grain- animal husbandry-speciality eco-economic region in the middle and low mountainous areas between Wulong County and Zilui County, Ⅳ the forest- fruit- animal husbandry- grain eco-economic region in the low and middle mountainous and hilly areas of Xingshan County and Yichang County. Through analyzing the eco -economic characteristics of each region, it puts forward their eco -economic developing direction and the strategies of ecological environment protection. Thus it can provide theoretical basis for agricultural sustainable development and ecological environment protection in the Three Gorges reservoir rea.
