Consideringthe uncertainties and vagueness of the evaluation indicators for the sustainable utilization of water resources, the K鄄L PPC model, based on the real鄄coded accelerating genetic algorithm, was developed in order to raise the resolutionof the evaluation model. A case study was conducted in the source area of the Tarim River. The optimal projectiondirection was determined through index optimization, grade determination, and model...
