Abstract
Previous studies have rarely revealed the characteristics and influencing factors of land use transformation (LUT) in poverty-stricken areas, where multiple actions of cultivated land protection are undertaken. The land use conversion matrix and Spatial Durbin Model were used to analyze the characteristics and influence factors of LUT based on remote sensing interpretation data of Sangzhi County in 2010, 2015, and 2018. The results demonstrate the following: (1) From 2010–2018, cultivated land, forest land, waters, and urban and rural construction land in Sangzhi County increased by 4.91%, 0.03%, 58.99%, and 55.63%, respectively, and grassland decreased by 13.32%. (2) Terrain, territorial, and traffic conditions were common influence factors of the land use type conversion (i.e., forest land to cultivated land, grassland to forest land, cultivated land to forest land, grassland to cultivated land, and cultivated land to urban and rural construction land). The conversion of land use type has a negative effect on the land use type conversion of adjacent townships. Territorial and traffic conditions affect the land use type conversion of adjacent townships. The results illuminate LUT at the township scale in mountainous areas and are beneficial to promoting the sustainable use of land resources and poverty alleviation.
Highlights
Land use transformation refers to the transformation process of regional land use patterns that correspond to the transformation of economic and social development stages that occur during a particular period of time [1,2]
Compared with the land use in Maotiao River Basin [13] and Karst Mountains in Guizhou and Guangxi Province [17], which are located in ecologically fragile areas, Sangzhi County undertakes the task of regional environmental protection and biodiversity conservation, and undertakes more tasks of cultivated land protection
The analysis of the influence factors of land use transformation demonstrated that land use transformation is the result of the interaction of natural conditions, the social economy, land systems, and policies in a specific region, and spatial spillover effects are observed in the interpreted and explanatory variables
Summary
Land use transformation refers to the transformation process of regional land use patterns that correspond to the transformation of economic and social development stages that occur during a particular period of time [1,2]. Many studies have extensively explored land use transformation. Studies have demonstrated that with the development of a social economy, a turning point occurs whereby continuous reduction switches to recovery, and this is termed forest transformation [5,6,7,8,9]. After World War II, the world economy entered a relatively stable period of development [10], with a rapid increase in urban population and an obvious change in global land use and land cover change. In the process of the rapid industrialization, urbanization, and agricultural modernization, the transformation of land use patterns was readily apparent
