| 摘 要： | 江河源区生态环境演变受自然因素和人文因素的共同作用,在自然和人文因素中究竟那些因素是该区生态环境演变的主导因素,对研究区域生态环境演变的机理和演变强度意义重大,本研究通过系统分析江河源区生态环境演变的过程,确立了影响江河源区生态环境演变的因素体系,建立了江河源区生态环境演变主导因素确定指标体系;全国范围内选择了40位在生态环境演变研究方面具有一定造诣的科学家进行了问卷调查和权重打分,用层次分析法(AHP)确定了温度、降水为主的自然因素和畜牧业为主的人文因素为江河源区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.

| Abstract: | The ecological environmental evolution in the river-source region of the Yangtze River,Yellow River and Lantsang River has been affected by natural and human being factors together.Knowing which are the leading factors in them is very important to study the evolutive mechanism and intensity of the regional ecological environment.In the paper,the ecological environmental evolution process was systematically analyzed and the factor system that affected the ecological environment evolution was established in t... |
