摘要
根据湖泊(水库)营养化具有模糊性的特点。建立了湖泊(水库)富营养化评价的模糊集理论与模式,并首次提出富营养化指标综合权重矩阵概念及其确定方法。应用该模式对我国12个湖泊(水库)的富营养化程度进行了评价,结论与实际情况相符。为湖泊(水库)富营养化治理和保护提供了科学依据。上述理论与模型原则上亦可在其他环境评价领域中应用。
In this paper, the fuzzy set theory and model of assessment for lake (reservoir) eutrophication are established on the basis of the fuzzy characteristics of eutrophication. Furthermore, the paper proposed firstly the concept and derived method of comprehensive weight matrix of eutrophication indices. The model is also applied to assessing the eutrophication situations of 12 lakes (reservoirs) in China and the results are correspondent to the facts. Therefore, the theory and model provide not only scientific basis for the treatment and reservation of lake (reservoir) environment but also a new method for the study on assessment for lake (reservoir) eutrophication.
The theory and model proposed in the paper are also adaptable to other environmental fields concerning assessment theoretically.
