Evaluation research of water resources shortage risk based on improved information diffusion theory
摘要
Abstract
In order to effectively evaluate the risk condition of water resources shortage ,using the improved informa-tion diffusion theory to determine the risk evaluatiog degrees ,selected 23 evaluatiog indexes ,based on the fuzzy compre-hensive evaluation model ,carried out the evaluation research of water resource shortage risk for the Shanxi Province .The results showed that:The risk vectors of Taiyuan , Yangquan , Xinzhou , Jinzhong and whole Shanxi Province were 0 .4461、0 .5189、0 .4258、0 .4019 and 0 .3685 respectively ,the risk grade was third level which belonged medium risk level .The risk vectors of Changzhi and Jincheng were 0 .3896 and 0 .3914 which belonged lower risk level .The risk vec-tors of Datong ,Shuozhou ,Luliang ,Linfen and Yuncheng were 0 .4818、0 .4865、0 .4576、0 .4082 and 0 .4597 respective-ly ,the risk grade was fourth level which belonged higher risk level .The model evaluation results were basically consis-tent with the local real situation of the water resources development and utilization ,it can be provided the guidance for the exploitation and utilization of regional water resources .关键词
