Based on six indexes: satisfaction situation of ecological water demand,standard-reaching rate of water quality in water function area,eutrophication index of lakes and reservoirs,longitudinal connectivity of rivers,reserve rate of important wetlands and status of important aquatic habitat,water ecological conditions of main rivers and lakes in the basin were evaluated. The results showed that the rivers with better ecology were mainly distributed in east mountainous area of Liaoning,such as the upper reaches of the Hunhe River and the Taizi River;the problems of water pollution,ecological water shortage and habitat shrinkage were widespread in the Liaohe River basin,and the situation of water ecological security in the Liaohe River basin still faced great pressure.展开更多

Based on historical data, on-site visits and field investigation, this paper analyzed the changes of fish resources in the lower reaches of the main stream of the Songhua River, so as to understand the current situation of three grounds and one channel and resources of fishes. This study provides reference for fish conservation in the lower reaches.展开更多

In this paper,the primary and secondary reserves in drinking water source area of the Shitoukoumen Reservoir are taken as research objects. Based on the theory of ecological compensation,the ecological compensation standard is accounted and determined from different perspectives,and the suggestion of the phased ecological compensation in water source areas is proposed.展开更多

In view of this, it is urgent to protect water ecological environment of the basin. This paper took the national ecological environment conservation instructions as the guidance, combined with the administrative division, planning and actual conditions of the basin, proposed principles and schemes for the grading of water spaces in the basin, as well as the hierarchic control requirements, to provide instructions for the conservation of the river basin.展开更多
