The scientific and objective screening methods of sand-barrier technology are an important basis for ensuring the sand-fixing technology to play its maximum role in a long-term and stable way. Aiming at the effect evaluation for sand-barrier technologies in the Beijing and Tianjin sand source regions, an evaluation system of sand-barrier technologies was established in this paper. We also defined the evaluation indexes and its weight, clarified the problems faced by the evaluation of sand barrier. Under the premise of sand-barrier technologies in harmony with the natural conditions, economic developmentand based on literature frequency method and analytic hierarchy process (AHP), the evaluation index system of sand-barrier technologies were screened from technology maturity, technology application difficulty, technology suitability, technology benefit, technology promotion potential 5 aspects. The final evaluation index system consisted of one index of judgment layer, four indexes of criterion layer, 14 indexes of indicator layer, and 25 indexes of sub-indicator layer., The index system, taking the technology benefit as the leading factor and considering the comprehensive evaluation of function and application, was used to carry out the full evaluation of sand-barrier technologies in the Beijing and Tianjin sand source regions. 参考文献 相似文献 引证文献" @default.
