Analysis of Land Use Structure in Liaoning Province Based on Lorenz Curves and Gini Coefficient

Abstract

Land resources and land use activities support the social and economic development in any region. In order to explore the distribution of land use structure, we can apply the Lorenz curves and Gini coefficient to accomplish. In this study, we selected the land use data in 14 prefecture cities in Liaoning Province of China from 2010 to 2015. Based on the Lorenz curve and the Gini coefficient, we analyzed quantitatively the land use structure in 14 prefecture cities of Liaoning province. Results indicated that cultivated land, forest land and construction land were evenly distributed, while garden land, grass land and unused land were distributed in a more concentrated state in space scale. On time scale, the Gini coefficient of forest land, garden land and grass land were increasing, and the degree of distribution dispersion has increased, while the Gini coefficient of cultivated land, construction land and unused land has reduced, whose distribution tended to equilibrium. Some suggestion for rational land use and structural adjustment has been provided by analyzing the spatial and temporal distribution of land use in Liaoning Province.
