- Abstract:
- In order to fully grasp the temporal and spatial differentiation characteristics of land systems and ecosystems, and promote the long-term coordinated development of natural ecosystems and social economic systems, we took the Three Gorges Reservoir area(Chongqing section)as the research site, and used Costanza's Ecosystem Service Value Equivalent Method to explore the spatial and temporal characteristics of land use transition and the ecosystem service value(ESV)in the study area from 2005 to 2018 based on land use data. The spatial auto-correlation theory was used to quantitatively explore the spatial distribution relationship of ecosystem service values and the spatial response characteristics between land use and ecological value, with a view to providing scientific support for optimizing urban spatial development models and promoting the coordinated and sustainable development of urban social ecology. The results suggest that the research area had the largest transfer rate of cultivated land and the highest transfer rate of construction land in the past 15 years; the active degree of land use transformation was consistent with the spatial distribution of ecosystem service value changes. The value of ecosystem services increased first and then decreased. Wuxi-Fuling was taken as the boundary, value of ecosystem services was low in the west and was high in the east, and it decreased in west and increased in the east; the spatial distribution of the value intensity of ecosystem services had a significant positive spatial autocorrelation, and the aggregation trend was obvious; land use degree and ESV had a significant spatial negative effect, and the most significant related areas were mainly located in the main urban area, the north of Jiangjin and the northeast edge of the research area.
