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。 -

生物評價結果認為，千島湖浮遊藻類平均密度較同類營養水平的淡水水體高，其所有取樣點浮遊藻類平均密度都10 ~ 6個? l ，國內外一般認為當浮游植物平均密度10 ~ 6個? l時，其已經達到富營養化水平，因此單從浮游植物密度來看，可以認為千島湖已達到水體富營養化。 -
As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china, more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ). based on the investigation of natural resource and agricultural distribution, the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied, and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis. according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001, the concentrations of toxic substance and heavy metal were under the monitoring limit, but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir
