Comprehensive Benefit Evaluation of Land Consolidation in Semi-arid Ecologically Fragile Area Based on GIS
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 eval-uate the comprehensive benefits of land consolidation.The results showed that the model could accurately reflect the spatial distribution charac-teristics 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 sys-tem 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.
