lake pollution
解釋
湖泊污染-
The research indicates that the modern sediment is divided three layers : polluted layer, transition zone and unpolluted layer. just the pollute layer cause dianchi lake environmental pollution. the high value district of ammoniac nitrogen distributes near northern part haigeng mainly, middle part increase slightly, have most lower near southern part, the content of ammoniac nitrogen of the polluted layer sediment lower than the lower layer ; the high value district of effective phosphorus distributes near haikou - jinning, from the north to the south, the content of effective phosphorus increases progressively, the content of effective phosphorus of the polluted layer sediment obviously higher than the lower layer

The water, which is the source of life, has a close relation with the growing of the human beings and the development of the city. the shore of river, ocean and lake is the cradle of humankind civilization. there is the original city in drainage areas of some rivers. the waterfront which has internal permanent attraction for humankind is the most sensitive area in urban environment and culture. however, at present days of the industrial civilization, with accelerating of urbanization and fastly enlarging of city size, some problems, such as the pollution of the environment, the lack of resource, the expanding of population, the traffic confusion, the unbalance of culture and the ecosphere crisis, have arised. these problems have badly influnced the development of urban waterfront. the whole world has know the importance of ecosphere crisis and the protection of environment but, how to treat the urban waterfront which is the typical environment of human living ? this article try to study the protection and utilization of resource, the development of economy and culture and the shaping of space landscape about the urban waterfront with the aspect of sustainablity development
但是在工業文明日益發達的今天，隨著城市化進程的加快和城市規模的飛速擴大所帶來的環境污染、資源衰竭、人口膨脹、交通混亂、文化失衡和生態危機等問題，嚴重地影響了城市濱水區的發展。生態危機和環境保護已經引起了全球的重視，而城市濱水區作為人類聚居的一個典型環境，該何去何從呢?本文試圖以生態學理論為基礎，用可持續發展的觀點從生態持續、經濟持續和社會文化持續等幾個方面對城市濱水區的資源保護和利用、經濟、文化的發展和空間景觀的塑造進行研究。 -
