Contrastive Analysis of Evolution of Land Use Structure in Developed Area and Developing Area——A Case Study on Suzhou of Jiangsu Province and Suzhou of Anhui Province
基于1998-2008年土地调查数据,对比分析江苏苏州和安徽宿州土地利用结构演变规律与差异,发现两地主要地类变化方向一致但幅度和速度不同,土地利用系统趋于复杂无序。
The contrastive study on evolution of land use structure in developed area and developing area can provide theoretical basis of sustainable land use.Based on the index model of number,extent change of land use and information entropy theory,using the land survey data of Suzhou of Jiangsu Province and Suzhou of Anhui Province from 1998 to 2008,the author analyzes and contrasts the regulations and differences on evolution of the land use structure.The result shows that in these 10 years : Main land types,such as agriculture land,settlement and incompatible industry land and transportation land,have the same change direction in this two cities,but the change ranges and speed of Suzhou of Jiangsu Province are more than Suzhou of Anhui Province;even through the index of land use degree are both highly,the index of Suzhou of Jiangsu Province is increasing quickly and in a high-speed development period and the Suzhou of Anhui Province is much slow,with years going,the gap of the index have become 9.36 in 2008;information entropy increases year by year with a tendency from fast to slow and the Suzhou of Jiangsu Province increases more quickly,so that land use systems become complex and disordered in two cities.The direction of land use in the future is to improve land use structure by taking actions that suit local circumstances.
