摘要
在分析黄河流域水生态保护形势的基础上,总结了流域水生态保护开展的主要工作,对黄河下游河流生态和河道生态用水保障、典型区域河口湿地生态保护与修复、近海生态修复状况和流域外供水区生态保护进行了分析。黄河水量统一调度、调水调沙、河口生态调度、生态补水、湿地修复等措施的实施,提高了河流基本生态流量满足程度,遏制了黄河下游生态系统不断恶化的趋势,下游生态环境得到了一定程度恢复;黄河下游河道湿地面积增加,河流湿地生态功能得到一定程度恢复;改变了黄河淡水资源的时空分布,黄河入海水量显著增加;河口地区生态环境得到改善。随着国家生态环境保护战略的实施,黄河流域着力加强了水资源管理和生态环境保护,初步遏制了流域水生态失衡的态势,水环境恶化趋势得到缓解,重要区域的生态得到修复。
The main work of the river basin water ecological protection was summarized based on the analysis of the Yellow River basin water ecological protection. The water security of the river and river course ecosystem in the lower Yellow River,the ecosystem protection and restoration of the typical regional estuarine wetland,the status of costal ecosystem remediation and the ecosystem protection of water supply area outside the basin were analyzed. The implementation of the integrated water regulation,water-sediment regulation,estuarine ecological regulation,ecological replenishment and wetland restoration of the Yellow River have improved the basic ecological flow to meet the river level,curbed the deteriorating trend of the lower reaches of the Yellow River ecosystem,and the ecological environment of the lower reaches has been restored to some extent. The wetland area of the lower reaches of the Yellow River has been increased,and the ecological function of river wetland has been restored to a certain extent. The spatial and temporal distribution of the freshwater resources of the Yellow River has been changed,and the water quantity flowing into the sea of the Yellow River has been increased significantly. The ecological environment of the estuary area has improved. The imbalance situation of river basin water has been preliminarily controlled,the trend of water environment deterioration has been contained and the important regional ecology is restored with the implementation of national ecological environment protection strategy and the strengthening management of water resources and ecological environment protection from the Yellow River basin.
