| 摘 要： | 为了形象直观的了解经济空间的发展状况,介绍了如何对经济数据实现基于格网的建模方法,并通过Surfer软件进行空间数据插值后建立空问趋势面。利用此方法绘制了江苏省人均GNP、第一产业、第二产业、第三产业、GNP、农业人口率等二维和三维趋势面图,通过它对江苏省的经济布局及其趋势状况进行了实证研究。结果表明江苏省经济发展存在着明显的梯度特征,三大区域之间的经济差距目前呈显著的扩大趋势。

| Abstract: | To comprehend the development of economic space intuitively, the paper introduces a modeling method based on grid. It builds the Spatial trend-surface after Spatial Data Interpolation by using Surfer software. The 2D and 3D trend-surface of GNP Per Capita, the First Industry, the Second Industry, the Tertiary Industry, GNP, and agricultural population rate are protracted using this method. The economic layout and economic trend of Jiangsu province are researched by using this trend-surface. The result indicates that the economic development of Jiangsu province exists visible grads and economic gap of three regions assumes remarkable expansible trend. |
