长江口地区水环境风险分析

Analysis on water environment risk of Yangtze River estuary

随着长江经济带发展战略的实施,长江口地区将会迎来新一轮的经济高速发展。然而水质污染、涉水工程建设以及咸潮入侵、湿地退化、赤潮频发等环境问题引发的水环境风险,将会导致该地区水资源供需矛盾进一步加剧。为此,进行了专项研究分析,对水环境风险影响因子进行了筛选和风险等级评估,同时还对长江口地区的重要风险因子进行了着重研究,在此基础上,提出了一些具有建设性的意见和建议,以期缓解和解决长江口地区目前存在的水环境风险。对长江口地区的水环境状况及其污染源情况、目前存在的问题及其应对措施等作了介绍。

With the implementation of Changjiang Economic Belt Development Strategy,Yangtze River delta area will enter into a new high-speed development period.However,the water environment risks induced by water quality pollution,water-related project construction,saline water intrusion,wetland deterioration,frequent red tide etc.will further aggravate the supply-demand imbalance of water resources.Therefore,we selected the influential factors involving water environment risk to evaluate the risk grade; meanwhile,analyze the main risk factors of Yangtze River estuary.On this basis,we put forward some productive advice to alleviate and solve the water environment risk.We introduced the water environment situation,the pollution sources,the existing problems of Yangtze River estuary and some countermeasures.
