主观和客观权重法相结合对化学固沙剂的引进筛选评价

Introduction and Screening Evaluation of Chemical Sand Fixing Agent by Approach Combining Subjective and Objective Weight Methods

建立包括3个层次的化学固沙剂引进筛选评价体系的框架。根据层次分析法和熵值法确定综合权重,对其指标进行赋权,并计算出生态可持续发展综合评价指数,7种化学固沙剂综合得分高低排序为:旱宝贝(56.666 7)>威海(11.686 6)>大连(11.200 3)>北京(8.253 2)>文安(6.337 3)>石家庄(5.860 6)>任丘(4.966 7)。该研究对化学固沙剂评价体系构建属于一次尝试性的工作,对于评价指标的选取也属于首次,指标的合理性有待于进一步结合野外实际应用效果进行完善,以利于指导化学固沙剂的筛选和应用。

A framework system including three levels is established for introduction and screening evaluation of chemical sand fixing agent. The comprehensive weight are determined by the analytic hierarchy process and entropy method to give the weights to the index and the ecologically sustainable development comprehensive evaluation index are calculated. The rank- ing of 7 chemical sand fixing agents based on comprehensive score is as follows： dry baby （56.666 7）〉 Weihai （I 1.686 6） 〉 Dalian （11.200 3） 〉 Beijing（8.253 2） 〉 Wenan （6.337 3）〉 Shijiazhuang （5.860 6）〉 Renqiu （4.966 7）. It is a tentative work to build a evaluation system of chemical sand fixing agents and it is also the first to select the evaluation indicators. The ra- tionality of the indicators need to be further improved on the basis of field application effect to be helpful for guiding the screening and application of chemical sand fixing agent.
