滁州市近30年来耕地数量与城市化之间协调性研究

On Coordination Between Urbanization and Farmland Area of Chuzhou City in Recent 30 Years

在不同的经济发展水平和增长阶段,耕地资源数量呈现不同的变化特征。研究区域耕地资源数量变动与城市化的协调性,对于正确认识和妥善处理经济发展与耕地资源保护之间的关系具有重要借鉴意义。本文基于滁州市1974―2004年近30年的统计数据,应用协调度模型分析方法,计算了滁州市1974―2004年耕地数量变化与城市化的协调度,并对其动态变化进行了分析。结果显示,滁州市耕地协调度与城市化明显呈阶段性分布,说明过去30年间滁州市耕地变动与城市化之间存在不协调因素。

The change of farmland area varies with the developing level and growth period of economy. Study on the coordination between regional urbanization and farmland is significant to understand and deal with properly the harmony between economical development and farmland protection. This paper analyzed the coordination relationship between urbanization and farmland area of Chuzh0u city from 1974 to 2004 based on statistical data. The result showed that there was a nonlinear relation between urbanization and farmland area, thus a coordination index model was established to calculate and analyze the coordination index between urbanization and farmland area. The variation of the coordination index with the time period implied that there were uncoordinated factors in farmland decrease during the urbanization.
