河流生态系统健康评价指标体系及权重的研究

On the Health Evaluation Index System and Weight of River Ecosystem

从河流生态系统的开发利用和可持续发展理念出发,总结学习相关文献,构建了河流生态系统健康评价指标体系,提炼出系统健康评价关键指标,利用层级分析法设计问卷,辅助于ExpertChoice软件计算出河流生态系统健康评价指标体系的权重,列出了影响河流生态系统健康建设的优先顺序,为河流生态的建设提供了依据和参考。

Following the idea of the river ecosystem utilization and the concept of sustainable development, a river ecosystem health evaluation index system is constructed.The key indexes of the system health evaluation are determined.Then, questionnaires are design based on the analytic hierarchy process and the index weights are calculated by using the Expert Choice software.The priorities of the ecosystem health improvement points are thus obtained, which provide useful basis and reference for the river ecosystem construction.
