基于生态过程的湖泊水文健康评价体系研究Ⅱ:应用
|
摘要
鄱阳湖是我国第一大淡水湖,随着经济社会快速发展,湖区各地均不同程度地承受着过度排污、过度采砂、过度捕捞等多重胁迫,相应地出现了水质恶化、河道形态破坏、生境退化等问题。监测结果显示,目前鄱阳湖最低生态水位满足程度较低,鄱阳湖处于净冲刷状态,同流量下水位降低,近年来鄱阳湖水位特别是枯季水位下降较为明显,鄱阳湖水文健康成为湖泊管理者关注的问题。本研究采用基于生态过程的湖泊水文健康评价方法对鄱阳湖水文健康进行评价,科学判定当前鄱阳湖健康状况,为鄱阳湖管理提供技术支撑。
Poyang Lake is the largest freshwater lake in China. Along with the rapid economic and social development, various areas of the lake are subject to multiple stresses such as excessive sewage discharge, excessive sand mining and overfishing. Correspondingly, water quality deterioration, river morphology destruction, degradation and other issues rise up. Monitoring results show that, the minimum ecological water level of Poyang Lake is less satisfied, Poyang Lake is in a net erosion state, and the water level is reduced. In recent years, the water level of Poyang Lake, especially in the dry season, drops obviously. The health problems of Poyang Lake are highlighted. This paper applies the lake hydrological health assessment system based on ecological process to evaluate the hydrological health of Poyang Lake and to judge its current state providing technical support for its management.
