应用模糊数学分析水质及预测污染负荷

提出关于水质和污染负荷的模糊分析方法，采用多因素模糊评判对水质进行单级或多级综合评判，根据最大隶属原理决定其水质好坏；采用模糊关系法预测污染负荷。用两极模糊综合评判，根据三峡库区香溪河长期观察资料进行了水质分析，得到合理的结果，引进工业污染的模糊关系，根据该地区有关资料，首次提出并采用模糊关系法预报了未来的污染负荷。

Analysis of Water Quality and Pollution Load by Fuzzy Set

There are many environmental problems with fuzzy character.Up to now people are used to employing the criterions.This paper proposed a new method-Fuzzy Set analyses.That means the multi-factor fuzzy synthesis assessment is used to judge the water quality and the fuzzy relationship method is used to predict the pollution load.We study the water quality by two-lever multi-factor fuzzy synthesis assessment method,basing on the long observations of the Xiangxi river in the Sanxia reservoir area.The result obtained is reasonable.It is important to predict the pollution load of the emigrant area of Yangtze river Sanxia hydroelectric power station construction.The fuzzy relationship factor of industry pollution is introduced.The pollution load in the future is predicted by this method,according to the related information of the area.This method is firstly presented and applicated in this paper.
