Research on Water Environment Crisis in Haihe River Basin and Moderate Recovery Stategy
摘要
20世纪50年代以来
海河流域水资源短缺和水环境恶化问题越来越突出。河道断流
湿地萎缩
地下水大量超采
水污染和水土流失加剧
流域水环境已经恶化到十分危险的境地。回顾、总结流域水资源开发利用的历史可以清楚地看出
经济社会发展大大超过了水资源的承载能力
是海河流域水生态环境恶化的根本原因。本文认为
改善和恢复水环境
必须以供定需
以水定发展
根据流域水资源条件确定产业结构、经济规模和发展方向
努力实现人与自然的和谐相处
以水资源的可持续利用保障经济社会的可持续发展。
Abstract
Water is an essential natural resource and a fundamental element of the ecological environment. A river basin has a limited carrying capacity of water resources and water environment. In recent decades
the rapid social and economic development brings about tremendous pressure on the rational exploitation and utilization of water resources in Haihe river basin. The unrestrained quest for water resources and irrational exploitation and utilization of the humanity have resulted in soil erosion
lake shrinkage
river closure and water body pollution. Due to excessive extraction
in several areas the groundwater tends to dry up. As a result
water table drops
giving rise to a number of serious problems such as ground subsidence and seawater intrusion
etc. More and more reservoirs have less water to store. The water resources and the water environment problem will be addressed with the strategic vision of sustainable socio-economic development and sustainable water resources utilization. As to recognize the water related environment of Haihe river basin
the history of the river basin must receive attention
and the experience and the lesson obtained in the modern times should be summarized and considered at the same time. The change of the environment is a gradual developing process that emerges step by step
which is not only related to the precipitation
temperature and the vegetation
but also the development of the human society. In this thesis
the water related environment issue for the sustainable development of the society as well as the philosophic opinion for the protection and proper recovery was mainly discussed.
