中部地区水环境污染及其防治建议

我国中部地区包括山西、河南、湖南、湖北、江西和安徽6省，中部地区整体水资源丰富，河湖众多，但由于在地区水资源开发中，过于追求地区的产值效益而忽视了环境效益，遗留下不少的水环境问题，如水体富营养化现象加剧、地下水水质污染程度进一步加重、水生态平衡失调以及其随之带来的中部地区水质型缺水问题。同时中部地区整体污水处理能力较弱、工业工艺流程水平较之东部发达城市较为落后，使得中部地区在社会、经济水平快速提高的前提下污水排放量和污染物含量也迅速增长，加之中部地区水环境保护措施的执行力度都较差，这也为中部地区的经济和社会发展都带来负面影响。根据中部地区水环境现状预测近、中期区域内各省废水排放趋势，分析中部地区水环境污染的主要原因，并给出合理的防治措施以促进中部地区经济的可持续发展。

WATER ENVIRONMENT PROBLEMS AND PREVENTION SUGGESTIONS IN CERTRAL AREA OF CHINA

With several rivers and lakes central area embracing six provinces （Sanxi，Henan，Hunan，Hubei，Jiangxi and Anhui） is an abundance area of water resources.However，lots of water environment problems occurred in this area now，such as water eutrophication and groundwater pollution，both are getting worse，and water ecology balance has been broken，because governments and factories in this area excessively chase after economic value，but disregarded the protection of environment.At same time，the wastewater treatment capability is low，the technology level is also underdeveloped in this area，following the development of society and economy these make discharging volume of the wastewater increasing abruptly in this area.The safeguard for water environment in central area also haven′t been executed effectively，these reasons bring negative effect on the economic development in central area.The article predicts the trend of wastewater discharging in near future from the present situation of water environment and the development direction in central area，and also analyses the key factors causing water pollution.Then，in order to pave the way for economy development in centre area of China some useful advices about how to control and prevent the pollution of water environment are given.
