The major faced problems at present in Yangtze river basin are: ① uneffective control in river water pollution threatens seriously the safety of drinking water; ② shrinkage of lake area and serious eutrophication; ③ soil-water losses degraded the ecological environment of the basin; ④ the impact of TGP and S-N water transfer project on water environment of the basin. In the light of above-mentioned problems, water resources utilization strategy must be adjusted and the sustainable social and economic development should be supported by sustainable water resources utilization, and it is necessary to take the following countermeasures: ① establishing overall flood control and disaster relief system; ② developing high water use efficiency agriculture; ③ taking "giving priority to water saving on the basis of pollution control" as urban water resources utilization strategy; ④ implementing comprehensive pollution control strategy with sources control as main point; ⑤ guaranteing water demand of the ecological environment; ⑥implementing the strategy of maintaining water resources supply and demand balance on the basis of water demand management; ⑦ studying countermeasures for the ecological and environmental impacts of trans-basin water transfer and western China devolopment. The key of realization of sustainable water resources utilization is to reform management and investment mechanism of water resources and water price policy. It is the only way to solve the water resources problems in Yangtze river basin as well as the whole China. 展开更多
