基于四元联系数原理的北京市郊安达木河生态评价

以北京市郊安达木河为研究对象,通过调查河流的生态特征、水文特征、地貌特征以及景观娱乐功能,在综合指数分析法的基础上,将集对分析的确定与不确定系统引入综合评价中,从相同、偏同差异、偏反差异、相异4个方面进行了分析,同时采用时间尺度和空间尺度相结合并着重从时间尺度上对评价结果进行分析。结果表明,近年来,安达木河局部河段生态环境遭到破坏,加强河流生态环境的治理,寻找农村垃圾合理有效的处理方式,减少不必要的人类活动对河流生态的影响,以及在发展旅游业和河流生态整治方面寻找平衡点,将成为下一步河流生态整治的重点内容。

Ecological Rank Evaluation of Andamu River in Suburban Beijing City Based on Principle of Four-element Connection Number

With Andamu River of suburban Beijing City as the research object,representative indices including river ecological features,hydrological characteristics,morphological features and landscape entertainment functions were selected in this study.Based on the comprehensive index analysis method with incorporation of certainty and uncertainty of pair analysis,the ecological environment of the river was evaluated and classified into four categories:same,partially different,largely different and totally different.At the same time,the evaluation results were analyzed by adopting spatiotemporal analysis.The results show that the local ecological environment of the Andamu River was almost completely destructed in recent years.Urgent measures such as strengthening river management,treating rural wastes reasonably and effectively,reducing unnecessary human activities and balancing tourism development and ecological management should be employed the key contents of river ecological regulation in the next step.
