四川省城市土地利用效率与经济耦合协调度研究

解决城市用地供需矛盾的关键是提高土地利用效率。为了测度城市经济与土地利用效率之间的协调程度，通过建立综合评价指标体系,利用因子分析法,对城市经济与土地利用效率进行综合评价,然后借鉴物理学中的耦合度函数，测算地级城市经济与城市土地利用效率之间的耦合协调程度。分别得到四川省18个城市1998至2008年的协调度，同时对不同地级城市、不同年份的计算结果作横向和纵向的比较，动态地分析与考察，结果表明四川省地级城市经济与城市土地利用效率的协调程度虽然逐步提高，但是总体上水平不高，只有发展经济与提高土地利用效率并举，才能改进协调度，从而为政府实施城市经济发展的可持续土地利用战略提供决策依据。

Study on Coupling Degree between Urban Economy and Land Use Efficiency in Cities OF Sichuan Province

The key to solving the contradictions between land supply and land demand lies in the improvement of efficiency of land use.To make right and scientific economic development strategies,the coordination between urban economic development and efficiency of land use is to be measured.By using comprehensive evaluation index system and factor analysis method,this paper makes comprehensive evaluation on urban economy and land use efficiency in18 cities of Sichuan province,This study works out a model of coupling degree between economic development index and efficiency of land use in different cities in order to get the coordination degree between urban economic development and efficiency of land use.The model reflects the urban development levels and coordination degree between urban economic development and efficiency of land use,giving a concise and systematic presentation of the system.Quantitative evaluation and comparison studies can be carried out by applying the model to investigate the coordination degree of land use and economy in a region or different regions in different periods.The data collected from statistical yearbooks of Chinese cities was calculated through the model to get the coordination degree during period of 2000 to 2008.Results show that the main problem facing Sichuan province ＇ s 18 cities coordination degree between urban steadily.The study also shows that the economy and efficiency of land use has been improving still are an urgent issue to be solved.The study suggests that the government should play a leading role in this regard and equal efforts should be made in developing economy and improving efficiency of land use so as to improve the coordination between the two to achieve sustainable development.
