Abstract:

This study, based on the land use change survey data from 2018, conducted a comprehensive analysis of the agricultural land consolidation potential in 113 administrative villages of Habahe County. Through GIS spatial analysis and hierarchical analysis methods, the potential of cultivated land was measured from two dimensions: quantity and quality. The research found that the area of agricultural land consolidation in Habahe County was 34482.41 hm², of which the existing cultivated land area was 30904.50 hm². After calculation, the quantitative potential of agricultural land consolidation could increase cultivated land by 2900.05 hm², with a new cultivated land coefficient of 8.41%. Combining the local crop planting structure system, it was calculated that agricultural land consolidation could increase cultivated land productivity by 3479.28 t. This indicated that Habahe County had significant potential for agricultural land consolidation. Based on the new cultivated land coefficient and the quality of cultivated land, the consolidation potential is divided into four levels. The research results point out that farmland construction in Habahe County should be supported by improving water and road infrastructure, strengthening farmland protection, and improving soil through agricultural biotechnological measures to enhance the quality of cultivated land, increase land use efficiency, and improve the output efficiency of cultivated land. The study provides a foundation and basis for future land remediation planning in this area.
