基于空间技术的农用地质量等别与经济耦合性研究

Research on the Coupling Between Farmland Grade and Economy Based on Spatial Technology

为了进一步丰富资源环境与经济社会发展相关性的研究,探讨农用地质量等别与经济的关联特点和耦合机制,按照农用地分等定级的基本思想与方法,测算各监测控制点的农用地自然等别、利用等别和经济等别,以镇为单位,以面积为权重,聚类监控点的自然等别、利用等别和经济等别。运用空间自相关方法,分析Moran散点图,研究农用地等别之间的关系,探讨农用地质量等别与经济耦合性。结果表明,农用地质量等别在空间上无序,而利用等别与经济等别较高的农用地主要分布在平原的水田,农用地利用等别与经济等别在空间分布上较吻合,经济耦合性强。通过聚类分析和空间技术模型,可以确定经济发展水平与耕地质量等别的空间耦合关系。

In order to enrich the relationship research between resource environment and economic development, discuss the coupling of agricultural land and economy, this paper depended on the basic rules and methods of farmland grade, these data from 23516 monitoring spots were collected based on Huazhou City, and the farmland nature grade, use grade and economic grade were calculated. The areas of towns were used to cluster the data of farmland nature grade, use grade and economic grade. The methods of spatial autocorrelation and Moran scatter diagram were used to study the relationships among farmland grades. The research showed that： the farmland nature grades were disorganized in space, but these farmlands which had preferable use and economic grades were distributed mainly over paddy field. And the results showed that the use grade was in good agreement with economic grade, the couplings between the two grades were closer.
