Analysis of land use change and its driving forces of county level in the cities' synchronization process

摘要

In the background of cities' synchronization, taking Liling city of Hunan province as a study example based on RS and GIS, using the remote sensing image, the land use change data and social-economic statistical data from 2003 to 2009, the land use change and its driving forces were studied. Firstly, the land use change of city was analyzed from the spatial differentiation, the size of change and the rate of change over the past decade. Secondly, using principal component and regression analysis to establish multiple linear regression models which included different land use types and studied the driving factors which affected the land use in Liling city. The results showed that the main factors which impacted the land use change in Liling city could be summarized to 2 factors: economic-technological development factors and the agricultural-technology development factors, the impacts of these factors were more significant to the land use change.
