城市化对珠江河口的生态影响及对策

Ecology effect and countermeasure of urbanization in Pearl River Estuary

城市化在给人类带来诸多益处的同时,也带来一系列严重的生态环境问题。珠江河口地区的快速城市化进程不仅引发了滩涂资源的过度开发利用,使得滩涂面积减少,而且影响了河口地区的水环境:水域面积减少,水质污染加重,洪涝灾害和咸潮频发。同时生物生存空间也遭到破坏,生物多样性减少,河口地区的生态环境遭到严重破坏。而且随着城市化进程的持续推进,这种破坏作用将继续扩大。为保障区域经济的可持续发展,做好珠江河口的生态环境保护工作,本文对此提出5条对策。

The Urbanization benefits the human, but also brings a series problem of ecological environment. The rapid urbanization in the Pearl River Estuary region, not only could cause the excessive use of tidal flat and the area decreased , but also influence the water environment, and reduce the water area, increase the water pollution, made floods and saline tide occurred frequently. Also, the biology survival habitat has been destroyed and biodiversity decreased, the ecological environment in estuary area has been damaged seriously. With the urbanization course proceeding, the damage will continue to expand. In order to ensure the sustainable development in the regional economy and protect the ecological environment of the Pearl River Estuary, 5 proposes are given.
