Evaluation Method and Application of Water Quota Based on Set Pair Analysis
The evaluation index system and grading standard of water quota were established,which were composed of coverage evaluation,normative evaluation,rationality evaluation,advanced evaluation and practical evaluation,in order to improve the level of water resource conservation,intensification,and safe utilization.Based on the theory of Set Pair Analysis,the evaluation model of water quota was constructed,and the poor indicators were identified by five-variable subtraction set pair potential analysis.This method was applied to the water quota evaluation of typical industrial indus-tries in the water shortage areas of North China.The results show that the overall evaluation result of water quota for the key industrial products of pharmaceutical manufacturing industry in Shandong Province is at a loose level.The set pairs of 7 indicators,such as industry category coverage ratio,are in the opposite or partial opposite trend trend,which can be used as the key content to be improved in the revision of water quota.The evaluation method of water quota based on Set Pair Analysis is systematic and practical,which overcomes the defect of incomplete coverage of evaluation indexes.It can provide reasonable and objective evaluation results of water quota,which is of great significance to ensure that water quota always meets the needs of water-saving management.
