综合指标法评价城市河流生态系统的健康状况

Comprehensive Index System for Evaluation of Urban River Ecosystem Health

探讨了河流生态系统健康的概念和评价方法。针对城市河流生态系统,建立了综合指标评价体系,运用层次综合法评价了济南市玉绣河广场东沟和西沟的健康状况。结果表明,东沟整体处于亚健康状态;西沟整体处于健康状态。因此,改善水质、修复水生物栖息环境是玉绣河后期治理的重点,还应加强东沟河滨带的休闲空间和景观生态建设。

The concept and evaluation method of fiver ecosystem health were discussed. A comprehensive index system for urban fiver ecosystem evaluation was established, and the health situation of the eastern channel and western channel of Yuxiuhe River in Jinan City was assessed by comprehensive hierarchical method. The results show the eastern channel is in sub-health state, and the western channel is in health state. Thus, the post-treatment of Yuxiuhe River should be focused on water quality improvement and hydrobiological habitat restoration, and the ecological construction of riparian recreation space and landscape of the eastern channel should be enhanced.
