汉江流域生态环境演变及恢复策略
摘要:汉江流域生态环境演变受自然因素和人文因素的共同作用,如何确定两者对区域生态环境演变贡献份额值的大小,从而解析出影响汉江流域生态环境真正成因,对研究区域生态环境演变规律和演变机制具有重大指导意义,本研究通过系统分析汉江流域生态环境演变的过程,确立了影响汉江流域生态环境演变的因素体系,建立了汉江流域生态环境演变主导因素的指标体系;本文利用层次分析法(AHP)确定了温度、降水为主的自然因素和工农业为主的人文因素为汉江流域生态环境演变的主导因素,并确定了各因素之间的排列顺序,并对该地区生态环境如何治理结合科学发展观提出自己的恢复策略。

Hanjiang River Basin ecological environment evolution and recovery strategy
Abstract:The evolution of ecological environment in Hanjiang River Basin which is under mon action of natural factors and human factors, how to determine the contribution value both on the evolution of the regional ecological environment which affecting the ecological environment of the Hanjiang River basin the real cause, has a great guiding significance to the study of evolution of the regional ecological environment and evolution mechanism, this study analyzed the process of ecological environment in Hanjiang River basin evolution through the system, established the influence system factors of ecological environment in Hanjiang River basin evolution, to establish the ecological environment in Hanjiang River basin evolution of the dominant factor determining index system; analytic hierarchy process (AHP) using the dominant factor determining the human factors of the temperature, precipitation and agricultural natural factors for the evolution of ecological environment in Hanjiang River Basin, and to identify the factors between the order on the ecological environment of the region, and how to bined with the scientific outlook on development is proposed to recover the strategy of their own.
Keywords: Hanjiang River Basin; Ecological Evolution; Dominant factor
