基于人类活动影响下衡水湖湿地生态用水安全分析

The Wetland Ecological Water Safety Analysis of the Hengshui Lake Based on the Influence of Human Activities

受人类活动的影响,衡水湖湿地供水水源主要靠外流域调水。在调水过程中,受沿途河道污染物的影响、引黄河水高含沙量对水质的影响以及衡水湖湿地周边工农业生产的影响,使得衡水湖湿地生态用水安全问题严峻。通过衡水湖湿地引水过程中对湿地水环境影响分析,包括供水水源分析、补水水质安全重要性分析、高含沙量对水质影响分析等,阐明衡水湖湿地供水安全中存在的问题,为恢复好保护衡水湖湿地提供科学依据。

Under the influence of human activities, the water supply source of the Hengshui lake wetland mainly relies on water from other river basin. During the process of water transfer,the contaminants of rivers along the watercourse,high sediment concentration of The Yellow River and the surrounding agriculture and industry of the Hengshui lake wetland lead to a severe wetland ecological water safety problem. Through analysis of the impact on the water environmental of the Hengshui lake wetland during the process of water transfer, including analysis of the water supply source, analysis of the importance of the supplemental water quality, analysis of the impact of the high sediment concentration on the water quality and so on, this article expounds the existing problems of the Hengshui lake wetland water safety supply and provides the scientific basis for the Hengshui lake wetland protection and restoration.
