【摘要】：河流是人类文明的发源地。随着经济的迅速发展和人数的急剧增长,河流生态系统急剧恶化,在此背景下,生态系统健康评价与治理逐渐引起国际社会的关注和研究。近年来,济南市社会经济迅速发展,但城区基础设施较差,水环境和水生态问题突出,河道水环境问题严重影响了济南市的水环境和城市形象。大辛河作为济南市东部新城的一条主要河流,起着防洪、排涝、景观、涵养生态的多重作用,近年来随着污染的加剧,生态系统状况急需改善。本论文在研究国内外河流生态治理经验的前提下,多方获取大辛河基础资料。首先,选取了水生态环境、河岸形态结构、河岸带状况及社会和经济四个层次的13个具体评价指标,建立了大辛河生态健康评价体系,利用模糊可变模型评价大辛河的生态现状健康与否。经计算,大辛河生态系统处于亚病态水平,得出需要保护和生态治理的结论。根据大辛河流域实际情况,通过河道蓄水、绿化美化、岸线柔化等生态治理手段,满足河道兼有城市防洪、景观建设、滨水游览的功能,达到水系的生态修复、恢复生物多样性、亲水和保护水质的目的,实现河道与城市的协调发展。
[Abstract]:Rivers are the birthplace of human civilization. With the rapid development of economy and the rapid increase of the number of people, the river ecosystem has deteriorated rapidly. In this context, ecosystem health assessment and governance has gradually attracted the attention and research of the international community. In recent years, the social economy of Jinan has developed rapidly, but the urban infrastructure is poor, the problems of water environment and water ecology are prominent, and the water environment and city image of Jinan are seriously affected by the river water environment. As one of the main rivers in the eastern new town of Jinan, the Daxin River plays many roles in flood control, waterlogging, landscape and conservation ecology. In recent years, the condition of ecosystem is in urgent need of improvement with the intensification of pollution. On the premise of studying the ecological control experience of rivers at home and abroad, this paper obtains the basic data of Daxin River. First of all, 13 evaluation indexes of water ecological environment, river bank morphology, riparian zone and social and economic levels are selected, and the ecological health evaluation system of Daxin River is established. The fuzzy variable model is used to evaluate the ecological health of Daxin River. The results show that the ecological system of Daxin River is at a sub-morbid level, and it needs to be protected and controlled. According to the actual situation of the Daxin River Basin, through the ecological control measures such as water storage, greening and beautification of the river course, and the softness of the shoreline, the river has the functions of both urban flood control, landscape construction and waterfront tour, so as to achieve the ecological restoration of the water system. The purpose of restoring biodiversity, hydrophilic and protecting water quality is to realize the coordinated development of river and city.
