淀山湖水环境质量动态研究

本工作为淀山湖富营养化现象的基础研究之一。通过引入L.A.Zadeh的模糊集合论以及汪培庄的模型识别直接技术,对八千个检测数据进行了动态分析:描述了淀山湖水环境质量的空间分布特征,以及它们不同水期随时间的变化。结论表阴,淀山湖水环境已受有机物污染,且污染程度与未处理即排入水体的有机废水量呈正相关,而与上游入湖的进水量成反比关系。冬季的水质污染状况尤甚。

Dynamic Approach on the Water Environmental Quality of the Dianshan Lake

Based upon a lot of data and dynamio analysis, the paper reveals that the pollution of water of the Dianshan Lake is correlative positively to the sews ge drained into the Lake before treated by sewage plant, and oorrelative negatively to the quantity of water flowing into the Lake from up-river. Monthly assessments of fuzzy idehtification show that the pollution situation in Winter is much worse than in other seasons.
