川西高原农牧业与生态环境耦合协调度量化研究

目的]研究农牧业与生态环境的可持续发展对于川西地区区域经济发展具有重要意义,为今后治理川西地区生态环境提供参考。方法]文章在分析川西高原农牧业与生态环境发展现状基础上,运用物理学中的耦合理论,构建耦合评价指标体系,并分析农牧业与生态环境二者间的耦合协调关系。结果]2000~2013年川西高原农牧业综合评价指数总体呈上升趋势,而生态环境综合评价指数总体呈下降趋势;耦合度在14年间基本保持在0.49左右;耦合协调度呈反复上升下降的波动趋势,总体呈下降趋势,变化率极小,耦合协调度的类型14年间都处于中度耦合协调。结论]农牧业与生态环境之间存在明显的耦合关系,二者相互作用,彼此影响。两系统耦合协调等级较低,均濒临失衡,而农牧业与生态环境之间的对比关系类型逐渐由生态环境敏感型转变为生态环境风险型,有向生态环境恶化型转变的趋势,各地区当中阿坝州的恶化情况最为严重,攀枝花市状况较好。

QUANTITATIVE RESEARCH ON COUPLING COORDINATION DEGREE OF ANIMAL HUSBANDRY AND ECOLOGICAL ENVIRONMENTIN THE WESTERN SICHUAN PLATEAU

The sustainable development between farming and animal husbandry and ecological environment is of great significance for regional economic development in western Sichuan.The coupling theory in physics and the evaluation index system of the coupling were used to analyze the coupling coordination between farming and animal husbandry and ecological environment. The results showed that in 2000-2013, the comprehensive evaluation function of farming and animal husbandryshowed an overall upward trend.The coupling coordination degree showed the volatility of up and down, but thecoupling coordination degree among the rate of change, the overall decline, and minimal change rate wasmoderate.The apparent coupling relationship between farming and animal husbandry and ecological environmentinfluenced each other.The types between the farming and animal husbandry and ecological environment gradually changed the ecological environment sensitive to ecological environment risk, which indicated a shift to the ecological environment deterioration.
