利用灰色关联分析方法,从经济生产、社会生产和生态生产角度出发对西昌市社会经济活动与生态环境之间的关系进行了量化研究。研究表明:农业产业的活动是影响水土流失的主要因素,换句话说,调控农业产业经济活动是生态环境维护的有效途径。生态生产、经济生产和社会生产之间存在明显的作用关系,这种作用关系不外乎表现在正作用和负作用两个方面,生态与经济的协调很大程度上依赖于对以上三类要素的合理调节。事实上, 就是利用以上三类生产要素的可塑性,通过产业经济活动的调控,弱化或消除产业与生态的矛盾,积极发展生态产业,这对西昌如此,对其他地区仍具有普遍意义。

The Gray Relation Analysis was used to quantify the related degree between economic, social and ecological production in Xichang.

Economic production was described using the index of per hectare output value of agriculture, per hectare output of grain, proportion of slope cultivated land use, social production using the index of population density, and ecological production using the index of forest coverage area, area and volume of soil erosion. It was concluded that the dominant factor is agricultural activities impact on soil erosion in Xichang. It means that supervision and regulation of agricultural activities is an effective approach to protect agricultural ecosystem. Ecological production is closely connected with economic and social production. The coordination between ecology and economy greatly depends on the rational regulation and management of social, economic and ecological productions. In fact, it is proved effective to relieve or eliminate the conflict between ecology and economy through above mentioned three factors supervision and management and development of ecological industry. Principles of this kind would be useful not only in Xichan but also in other areas.
