县域土地变化效应与新型城镇化耦合分析——以广西上林县为例

Ecological Effect of Land Use Change and the Analysis of the New Type Urbanization Coupling:A Case Study of Shanglin County of Guangxi Province

以广西上林县为研究区域,构建了小城镇土地利用变化生态效应与新型城镇化的耦合评价指标体系,运用ArcGIS和FRAGSTATS软件,利用TOPSIS法和耦合模型测算了土地利用变化生态效应和新型城镇化之间的耦合度,以期为城镇生态环境的优化与新型城镇化的健康发展提供科学和理论依据。研究结果显示：2009—2012年,上林县土地变化生态效应与新型城镇化的耦合度呈现不断上升的趋势,但其数值依然偏低,在0.488~0.5之间,处于颉颃阶段。2011年其耦合度达到0.5,有向磨合期过渡的趋势,但总体来看,二者的关系仍处于不协调状态。

This research constructed an evaluation index system between the ecological effect of land use change and the new type urbanization, taking the Shanglin county as an example. This paper used TOPSIS and coupling model to calculate the coupling degree between the ecological effect of land use change and the new type urbanization, which was based on using ArcGIS and FRAGSTATS software. The final data can be provided as scientific and theoretical basis for the optimization of the ecological environment and healthy development of new type urbanization. The results show that the coupling degree between ecological effect of land use change and the new type urbanization presents a rising trend from 2009 to 2012, but its value of coupling degree is still low. The coupling value is between 0.488 and 0.5, which can be demonstrated on antagonistic stage. In 2011, the coupling degree reached 0.5 with a tendency in a period of transition changing from low to high. Overall, the relationship between them is still in a state of disharmony.
