摘要
依据建立的水资源可持续利用的分级标准在各等级取值范围内随机生成数据作为样本,采用投影寻踪的思想优化投影方向,得到客观权重,并与层次分析法得到的主观权重相结合,建立了基于投影寻踪的模糊综合评价模型,并将模型应用于海南省水资源可持续利用综合评价。结果表明,该模型计算简便,评价结果可信度较高。
Based on established grading standard for sustainable utilization of water resources,the randomly generated data in the spans of all the grades were used as samples.Using thought about projection tracing,the projection direction was optimized and the objective weight was obtained,then the fuzzy integrated evaluation model based on projection tracing was established through combining this objective weight with subjective weight obtained through analytic hierarchy process.And this model was applied in the integrated evaluation on the sustainable utilization of water resources of Hainan Province.The results showed that this model was simple and convenient for calculation and the confidence level of evaluation results was higher.
