Cloud Model of Water Resources Reproducible Ability in the Yellow River Basin
Xiaonan Chen · Chinese Journal of Population Resources and Environment · 2010
In order to evaluate water resources reproducible ability efficiently in region,a synthetic assessment model based on the cloud theory is suggested.The paper establishes assessment indexes system,calculates weights of indexes by fuzzy method,and describes evaluation grade of water resources reproducible ability under single index for each districts.The new evaluation model can not only show the fuzzy feature of grade,but also indicate random attribute of the degree by hyper entropy.The paper applies the model into assessment of the water resources reproducible ability of 9 regions in the Yellow River Basin.Results show the water resources reproducible ability in the Yellow River basin is weaker,and the abilities in Ningxia and Inner Mongolia are the weakest.Some measures must be taken to improve the water resources reproducible ability in the Yellow River Basin.
