黄河流域河湖生态环境复苏研究

Eco-environment recovery of rivers and lakes in the Yellow River Basin

通过评价黄河流域河湖生态环境演变特征,探究其存在的问题,分析黄河流域河湖生态环境复苏目标与总体格局,探讨并提出黄河流域河湖生态环境复苏的实现路径。结果表明,黄河流域河湖生态环境系统正在由无序发展向有序发展转变。针对黄河流域河湖生态环境复苏面临的河湖生态环境脆弱、区域地下水超采、流域水土流失等主要问题,应从强化河湖监管、提升河流生态廊道功能、实施地下水超采治理与监管、加强黄土高原水土流失综合治理等4个方面入手,促进黄河流域河湖生态环境的全面复苏。

In this paper, the evolution characteristics of eco-environment of rivers and lakes in the Yellow River Basin are evaluated, and the existing problems are analyzed. Then, the goal and pattern for the eco-environment recovery of rivers and lakes in the Yellow River Basin are discussed. It is found that the eco-environmental system of the Yellow River Basin is changing from disordered development to orderly development. The main problems of eco-environment recovery are as follows: fragile river and lake eco-environment, regional groundwater overexploitation, water and soil erosion in the river basin. In view of those problems, it is concluded that strengthening river and lake supervision, improving the function of river ecological corridors, implementing groundwater over-exploitation control and supervision, and enhancing the comprehensive control of soil and water erosion on the Loess Plateau are the main ways for the overall eco-environment recovery of rivers and lakes in the Yellow River Basin.
