黄河三角洲及附近海域综合治理战略研究

Study on Creating an Integrated Management Strategy for the Yellow River Delta and Its Ambient Sea Area

针对黄河三角洲及附近海域的生态环境现状和主要问题,从黄河三角洲是河—陆—海体系一部分的角度,提出了黄河三角洲及其附近海域综合治理战略:(a)通过多流路和科学调度,把黄河水沙营养物相对均匀地输送到黄河三角洲沿岸各处,(b)把河口河道整治成相对窄深的河道,以节约黄河口输沙水量;(c)利用黄河泥沙,淤高三角洲洲面,增加地下水埋深,改良盐碱地;(d)在渤海西岸及其上游地区实施陆海统筹的环境管理和污染治理。

Since the Yellow River Delta is a part of the river-land-sea system, the paper proposes a new strategy for creating an integrated management system for the delta and its interconnected bodies of waters based on current ecological and environmental issues. The strategy advocate：（a） ensuring relatively even distribution of the Yellow River＇s water, sediment and nutrients along the delta＇s coast via multiple avenues of dissemination and scientific management methods;（b） making the channel on the delta narrow and deep to economize water volume for sediment transportation to the sea;（c） making good use of river sediment to raise the height of the delta and increase the groundwater depth and reduce soil salinity; and（d） implementing land-sea integration policies on the western coast of the Bohai Sea and its upper area to manage the whole region＇s environmental resources and reduce pollution in the delta＇s waters.
