Relevant suggestions on water ecology protection are proposed, such as implementing relevant laws and policies, controlling total sewage discharge, optimizing water resources allocation, and enhancing wetland protection, fish resources protection, comprehensive management of small watershed and water ecology compensation. The research could provide certain reference for protection and restoration of water ecology in the watershed.展开更多

However in recent years,due to the reduction of natural precipitation,human activities and other causes,wetland shrivels and degenerates,biodiversity reduces,and ecosystem security is threatened. In this paper,the rivers and lakes connecting project in western Jilin Province is proposed to restore the damaged wetlands and protect important wetlands.展开更多

The forecast results show that if the measures don＇t be taken to protect eco-environment, the stress coefficient still grows, and the stress degree aggravates. In view of the above situation, we take the measures to lighten eco-environment stress, and promote the coordi- nated development of resources, environment and social economy, which is linking rivers and lakes, water resources optimization, preventing and controlling the desertification and the salinization, improving the degenerated grassland.展开更多
