望虞河西岸水生态系统协同效应评价
Synergistic effect evaluation on water ecosystem in western area of Wangyu River
摘要
Abstract
The overall management of the water ecosystem is the key and difficult point in water ecological environment protec-tion in the new era.The mechanism of the water ecosystem is complex,and each subsystem has a close influence and feedback re-lationship.It is very important to clarify the synergy mechanism among water ecosystem subsystems.Therefore,the water ecological environment functional zoning(zoning for short)on the west bank of Wangyu River was taken as the evaluation unit,and the three subsystems of water environment,sediment,and water ecology were taken as the research objects.Based on the measured da-ta of the high-flow and low-flow seasons in 2019,a synergistic effect model was established to quantify the synergistic effect a-mong the research objects in the evaluation unit,explore its spatial and temporal differences,and identify its main limiting factors.The results demonstrated that:①The environmental condition in the high-flow season was more conducive to the growth of zoo-plankton and the dilution of pollutants in the water,then the synergistic effect was stronger than that in the low-flow season.②The sub-regions with moderate synergy and strong synergy were distributed in the shore area of Taihu Lake and Wangyu River,which showed that the water ecological environment management and restoration projects in these sub-regions had achieved ini-tial results,and the coupling of the three subsystems tended to be good.The sub-regions with light synergy and non-synergy were clustered in the"triangle area"which was in the east of the Xicheng Canal and south of the Changjiang River.Referring to the evaluation results to take precise actions based on different functional zones and classifications can improve the implementation efficiency of pollution prevention and control as well as ecological restoration measures in the western area of Wangyu River.关键词
