Abstract:

This article took Fengjie County in the hinterland of the Three Gorges Reservoir Area as the study area, based on the land use data in 1980, 2000, 2010 and 2020, analyzed the dynamic change process of land use in Fengjie County from the “whole region-local” scale by adopting the methods of dynamic degree of single land use, regional division and land use pattern division, cleared the evolution path of land use and explored its driving mechanism. The results showed that: 1) The overall performance of land use change in Fengjie County and other small areas was consistent from 1980 to 2020; forest land, orchard, abandoned land and urban and rural settlement land continued to increase, while grassland, shrub land and cultivated land continued to decrease. 2) The land use evolution of Fengjie County tended to be ecological conservation, while the small areas were mainly manifested as single grain supply type and eco-economic cooperation type, comprehensive development of grain supply and eco-economic cooperation type, and gradual transition from grain supply to eco-economic cooperation type. 3) The land use evolution of Fengjie County was influenced by the comprehensive role of natural, the construction of the Three Gorges Project, socio-economic and policy factors from 1980 to 2000, and the land use was mainly affected by the construction of the Three Gorges Project, socio-economic and policy factors from 2000 to 2010, while it was mainly restricted by socio-economic and policy factors from 2010 to 2020.

Key words: land use, Three Gorges Reservoir Area, evolution path, Fengjie County
