Abstract

The connotation of county-level land consolidation is centered around human beings, based on ecological protection and restoration, with coordinated development of multiple elements and dimensions, promoting urban-rural integration and high-quality development of county-level space. This study started from the perspective of territorial spatial integration and analyzes the concept and connotation of urban fringe areas based on comprehensive land consolidation, revealing the important significance of land consolidation for the high-quality development of urban-rural transition areas. Explored the goals and priorities of land consolidation from two aspects: functional supplementation and urban-rural integration, and clearly proposed that ecological governance and restoration should be the core; Based on Google Earth Engine (GEE) and Geographic Information System (GIS), quantitative analysis was conducted on the spatiotemporal changes in ecological quality before and after land consolidation in the project area, clarifying the impact of comprehensive land consolidation on ecological quality. From 2010 to 2020, the RSEI of the comprehensive land improvement project in Shichuan River Basin showed a continuous upward trend, increasing from 0.475 to 0.592, an increase of 24.63%. The area with poor ecological level decreased by 95.07%, and the ecological environment quality in the eastern part of the study area was significantly higher than that in the western part, achieving significant results in ecological construction.
