文档介绍：河流污染生态治理研究——以甘肃藉河为例 Tackling River Pollution Ecologically —— A Case Study on the Ji River of Gansu Province 摘要河流污染是我国水资源的突出问题之一。本文以甘肃藉河为例,应用植物群落自然净化水质的原理,采取功能分区的方法,对西北地区城市河流的污染提出了具体的治理方案。将藉河城区段主要分为三个部分:(1 )上游生态过滤区;(2 )中游生态景观区;(3 )下游生态净水区。然后, 分区进行具体设计。此研究方案是藉河一期改造工程的一部分。目前, 一期工程已经完工,取得了较好的生态效益和经济效益。 Abstract Against the background of conspicuous problem of river pollution in China ’s water resources affairs, we made a case study on the Ji River of Gansu Province to apply the principle that water can be naturally purified by munities to the functional division and tackling plan of the urban rivers in northwest China. The urban leg of the Ji River is divided into three parts. They are the ecological filtration area at upper reaches, the ecological landscape area at middle reaches and the ecological purifying area of lower reaches. Each part has been designed to form the study as ponent of the first stage of Ji River ’s reconstruction which has pleted and has got satisfactory ecological effect & economic benefit. 众所周知,河流污染是我国水资源的突出问题之一,已经严重影响人民的生产和生活, 阻碍经济建设的发展,对人类生存和生态环境造成巨大威胁。据统计, 2002 年全国工业和城镇生活废水排放总量为 亿吨,比上年增加 % 。其中工业废水排放量 亿吨,比上年增加 % ;城镇生活污水排放量 亿吨,比上年增加 % 。 As is known to all, river pollution as the conspicuous problem of water resources affairs influences on production and people ’s livelihood, being a hurdle in economic development and a threat to m
