黄河上游甲积峪小流域生态系统管理能力动态评价

Evaluation on ecosystem management capacity dynamic of Jiajiyu catchment in upper reaches of the Yellow River

对小流域生态系统管理水平进行有效评价,可为管理者制定相应对策提供依据。在生态环境领域系统评价方法综述的基础上,通过构建指标体系,应用层次分析法对黄河上游甲积峪小流域生态系统管理水平进行了动态评价。研究结果表明,1999年至2006年该小流域生态系统管理能力处于一般偏差水平,但正在向好的方向发展;所建立的指标体系和分级标准对评价黄河上游小流域生态系统管理水平,具有一定的适用性;单指标评价和指标综合评价、静态和动态评价各有优势,只有互相补充才能更好地评价小流域生态系统管理能力。

Evaluation on ecosystem management capacity of catchment can provide important information for decisionmakers, so that they can take effective measures to strengthen catchment management. The indicator system of comprehensive evaluation on catchment management capacity was designed and the ecosystem management capacity dynamic of Jiajiyu catchment in the upstream of the Yellow River was evaluated with the method of analytic hierarchy process （AHP）. The results showed that： （ 1 ） the level of ecosystem management capacity for Jiajiyu catchment was low, though it keep increasing from 1999 to 2006; （2） the develoed indicator system and its classification showed feasibility in evaluating the ecosystem management capacity of catchment in upstream of Yellow River; and （3） although single-indicator evaluation and integrated indicator evaluation, static and dynamic evaluation possessed advantages respectively, integrated application of different methods would achieve more reasonable evaluation results of ecosystem management capacity for catchment.
