宁夏阅海湖生态需水量计算与保障对策研究

阅海湖是银川市内最大的人工湿地,近年来随着经济社会的发展,湿地生态环境面临严重威胁,维持湖泊生态水量是保证湖泊生态系统健康的关键。本文采用水量平衡法,计算出阅海湖的基本生态需水量及适宜生态需水量,并从节水、开源截污、制度保障3个方面提出生态水量的保障对策,可为水行政主管部门合理配置水资源、保护生态环境提供理论支撑。

Study on ecological water demand calculation and guarantee countermeasures of Yuehai Lake in Ningxia

Yuehai Lake is the largest constructed wetland in Yinchuan.In recent years,with the development of economy and society,the wetland ecological environment is facing a serious threat.Maintaining the ecological water quantity of the lake is the key to ensure the health of the lake ecosystem.In this paper,the water balance method is used to calculate the basic ecological water demand and suitable ecological water demand of Yuehai Lake,and the protection countermeasures of ecological water quantity are put forward from three aspects:water saving,open source and sewage interception,and system guarantee,which can provide theoretical support for water administrative departments to rationally allocate water resources and protect ecological environment.
