摘要
文章对2002年-2008年梅江上游五华县境内水环境和水文调查数据进行了分析,结果表明:梅江上游五华段水体中铁、锰元素超标严重,同时存在着一定的有机污染,造成了水生生物的种类和数量不断减少,影响了五华县域经济可持续发展;五华河近30年的河床演变,水土流失问题依然存在,主槽下切的程度有逐年增加的趋势,跟上游来水、来沙条件及水沙关系变异、小水电、无序挖沙等人类活动等密切相关。最后从环境管理、污染源防治和区域综合整治等方面提出了相应的对策。
This study analyzed the 2002 -2008 water environment data and hydrological surveys of the upper stream of Meijiang within the Wuhua section. The results indicate that the iron and manganese in this river section exceed the allowed. The organic pollution of the water body resulted in aquatic species and population reduction and formed a direct impact on sustainable economic development of Wuhua County. Analyzing Wuhua riverbed evolution of almost 30 years, the problem of soil erosion still exist and the extent of the cuts of the main channel is increasing. It has a close relation with upper stream water and sediment con- ditions, variation of water and sediment ratios and human activities, such as small hydropower, disordered sand - excavating etc. Finally, the corresponding countermeasures are proposed from environmental management, pollution prevention and regional integrated remediation.
