摘　　要：科学评估土地整治综合效益对于提高土地利用效率、改善农村居民生产生活质量以及进一步落实乡村振兴战略具有重要意义。以半干旱生态脆弱区永昌县为例,采用熵权法和模糊综合评价法对其进行土地整治综合效益评价。结果表明:构建的模型可以准确体现各准则层指标的空间分布特征;整体土地整治综合效益评价中,综合效益等级为“优”,土地整治中生态效益对整体的提升作用最大。构建的土地整治综合评价体系可对研究区低效用地的整理整治,提升耕地质量,优化土地利用结构与布局提供借鉴。Scientific evaluation of the comprehensive benefits of land consolidation is of great significance for improving the efficiency of land use,improving the production and living quality of rural residents,and further implementing the rural revitalization strategy.Taking Yongchang County in semi-arid ecological fragile area as an example,entropy weight method and fuzzy comprehensive evaluation method were used to evaluate the comprehensive benefits of land consolidation.The results showed that the model could accurately reflect the spatial distribution characteristics of each criterion layer index.In the comprehensive benefit evaluation of land consolidation,the comprehensive benefit grade was“excellent”,the ecological benefit had the greatest effect on the overall improvement of land consolidation.The comprehensive evaluation system of land consolidation established in this paper could provide references for the consolidation and improvement of low-efficiency land in the study area,improving the quality of cultivated land,and optimizing the structure and layout of land use.
