Unascertained measurement evaluation model of environmental effection on Nujiang development

摘要

The uncertainty of index system was descried using rnmembership function, and the knowledge information in rnindex rnmembership about object elassifieation was studied. A rncomprehensive evaluation model of unascertained rnmeasurement was rnestablished according to the analysis of contribution rnof index to sample classification and the conversion rnmethod of membership rndegree from index to sample. The results indicate rnthat this model can be used to evaluate the rnenvironmental effect of water rnconservancy and hydropower development of nujiang.
