喀斯特地区农用地利用社会经济效益与生态环境效益耦合关系分析——以遵义市为例

Analyses of Coupling Relationship between Economic-social and Benefits Ecologicenvironmental Benefits of Agricultural Land Usage——Taking Zunyi City as an Example

通过构建农用地利用效益评价体系,利用熵权法和耦合度模型,对遵义市农用地利用效益耦合关系从时间和空间上进行了研究。结果表明,2004-2012年遵义市农用地利用的社会经济效益在波动中总体呈上升趋势;生态环境效益也发生了变化,但总体呈稳定态势,农用地利用效益耦合度总体水平较高,呈上升趋势;2012年遵义市农用地利用效益耦合度分布大致呈同心圆形,随着与区域中心距离不断增大,耦合度不断下降;农用地利用的社会经济效益与生态环境效益差异越小,说明农用地利用越协调,耦合度越高。结合遵义市经济发展情况和区域功能定位,提出了提高农用地利用耦合度、促进农用地协调利用的建议。

By establishing the evaluation system of agricultural land usage benefits, means of entropy-weighted and the coupling model were used to study the coupling relationship of agricultural land usage benefits in Zunyi city from the time and space series.The results showed that economic-social benefits of agricultural land had upward trend of changes from 2004 to 2012. Ecologic-environmental benefits changed. The overall situation was stable. Coupling relationship degree of agricultural land usage benefits had high level on the whole with upward trend. In 2012,coupling degree distribution approximately presented the concentric circular and decreased continuously with the distance from the increase of regional center. The difference between economic-social and ecologic-environmental benefits was smaller. More coordinated use of agricultural land,the higher coupling degree. Combining with economic conditions and regional function positioning of Zunyi City, some advices were put forward to improve agricultural land use coupling degree and promote coordination of agricultural land use.
