Abstract:

The purpose of this paper is to provide a scientific basis to optimize the land use structure and to promote conservation and efficient use of land resources by analyzing the evolution and driving factos of land use structure in the highly urbanized area.The land survey data of Suzhou and the model on number change,extent change and spatial change of land use were used to analyze the evolution of the land use.The results show that between the year 1998 and 2008,the cultivated area of Suzhou had reduced significantly and the structure of agriculture land had adjusted.Settlement and incompatible industry land area had increased dramatically and it was significantly negatively correlated with the reduction of arable land.The index of land use degree increased year by year.Kunshan had the greatest relative change rate on arable land,garden land and urban land.Zhangjiagang and Wujiang,respectively,had the greatest relative change rate on towns land and incompatible industry land.The main driving factor to economic society were discussed by means of the principal component analytical method.Through the above analysis,it would be concluded that the main driving factors affecting the evolution of the land use structure were population growth,economic development,industrialization and urbanization.The direction of land use in the future is to take the intensive urbanization,achieve “efficiencybased” land use patterns and focus on the combination of social,economic and ecological benefits
