鄱阳湖水生态现状与保护对策初探

Preliminary Study on Water Ecological Situation and Protection Countermeasure of Poyang Lake

受气候变化和人类活动影响,鄱阳湖水文情势大幅波动、水生态环境有退化趋势。本文基于鄱阳湖水资源、水环境、水生态等相关实测资料分析,系统梳理鄱阳湖水生态现状,目前江西省对河湖生态环境保护持续推进,保护力度逐渐增强,鄱阳湖整体生态环境趋于稳定;凝练鄱阳湖水生态面临的主要问题,主要是湖泊生态调节能力不足,河湖连通性受阻,河湖水生生物多样性下降;结合社会经济发展趋势,提出水生态保护对策,包括提升河湖生态调节能力,实施重点区域生态保护和修复,增强水生生物多样性保护以及加强水土保持生态建设,为鄱阳湖生态环境可持续发展提供了决策参考依据。

Affected by the climate change and human activity, the hydrological regime of Poyang Lake has changed greatly, and the ecological environment is degenerating slowly. This article based on the measured data of water resources, water environment and water ecology of Poyang Lake, gives a systematic account of status, at present, Jiangxi Province continues to promote the protection of the ecological environment of rivers and lakes, and gradually strengthens the protection, and the overall ecological environment of Poyang Lake tends to be stable. This article summaries problems;lakes lack the ability of ecological regulation;the connectivity of rivers and lakes is blocked, and the aquatic biodiversity of rivers and lakes decreases. Then it puts forward countermeasures combined with the social economic development, such as improving the ecological regulation capacity of rivers and lakes, implementing ecological protection and restoration in key areas, enhancing the protection of aquatic biodiversity and strengthening the ecological construction of soil and water conservation.
