太湖水环境面临的主要问题、研究动态与初步进展

本文对太湖水环境研究作了一个简单的回顾，指出了这几十年工作所取得的成就，如太湖进出污染物调查和水质评估，太湖水体光辐射观测与模拟等，结合国家有关主湖治理措施与方案，提出了“九五”工作应该着重在湖泊生态管理模型，水土界面主蓝藻水华爆发机制等领域，通过对当前国际上在这些领域中研究进展情况的回顾，特别介绍了在湖泊水动力学的观测，解释，模拟和应用方面，在湖泊藻类生长以及水结出现与湖泊光照条件，营养盐水平的

A Review and Prospect about the Aquatic Environment Studies in Taihu Lake

Taihu Lake is a large and shallow lake located in the delta of the Changjiang River. It is an importment lake since it undertakes the drinking water supply, the transportation,sightseeing and culturing. In the last decade, this lake is suffering from the eutrophication caused by industrialization around the lake area. This paper attempts to summarize the research activities and conclusions in Taihu Lake in the past several decades. According to the current urgent requirements of the countermeasures to harness deterioration of lake environment suggested by the governmcnt, some key problems that should be addressed in the Ninth 5-year Plan are put forward, i. e. the lake management model which will be based on the hydrodynamic processes coupled with the diffusion and migration processes of nitrient and algae, the mechanism of the occurrence of Cyanobacteria bloom, the releasc of nutrients from sediments. By the survey of literature in the international journals, a prospect about the relevant topics have been reviewed and the wantings have becn revcaled. Finally, the primary conclusions of the ongoing research projects have been summarized.
