- Abstract:
- With the completion of storing water and urbanization in the Three Gorges Reservoir Area, the land and economic structure of the Reservoir Area have changed significantly. Based on the theory of coordinated development, the Landsat TM images of the Three Gorges Reservoir area in 2000, 2007, 2014 and 2017 were used as land use data sources. The land use change data were obtained by RS and GIS technology. The evaluation index system of coordinated development degree of land use system and economic system was established by combining with social and economic data, and the coordinated development degree model was used to evaluate the coordinated development degree of the Three Gorges Reservoir area before storing water in the reservoir. The coordinated development degree during the stable period of water storage was calculated accurately. The results show that:(1)the degree of coordinated development of land use system and economic system in the Three Gorges Reservoir area presented the obvious upward trend from 2000 to 2017, with 88% of the districts and counties entering the stage of medium-level coordinated development;(2)the main reason for the low degree of coordinated development of the reservoir area from 2000 to 2014 had changed from the lag of economic development to the lag of land use, leading to the coordinated development of the reservoir head, tail and middle in 2017, there were two extremes reasons for the low degree. This study can provide references and decision support for the sustainable development of land use and economy in the reservoir area in the post-Three Gorges era.
