区域经济空间过程阻力面模型的初步研究

经济过程是各种要素流集聚和扩散的过程，在此过程中要素流的运动必然受到阻力的作用。基于此考虑，提出了经济过程阻力面模型，用以表示一个地区经济过程阻力的空间分布以及经济过程的运动趋势。空间经济过程阻力面模型对研究要素流的运动和区域发展战略规划有积极的启示意义。以浙闽赣（ZMG）边界区案例分析为例，模型计算得到的ZMG阻力面图比较客观地反映了浙闽赣交界区的物资流的阻力状况。ZMG边界区正如温台、闽南、江西经济发达区内的一个高阻力值的“岛”，从ZMG阻力面图可以看到有两个峰，一个在浙闽交界区（庆元、景宁），另一个在闽赣交界区（光泽、邵武）。在浙江境内的阻力线密度大、阻值高，说明浙江境内物资流动的地区差异明显。两峰之间为鞍（通），武夷山市处于这个“鞍”之上，同时展示了该模型在启示省域边缘带发展规划中的现实作用。

A PRELIMINARY STUDY OF RESISTANCE SURFACE MODEL OF REGIONAL SPACE-ECONOMIC PROCESS--CASE ANALYSIS ON ZHE-MIN-GAN BOUNDING AREA

The economic process is a period during which various kinds of elements flows assembled, diffused and transfered. Hence their movement is inevitably affected by the resistance in this process. Based on the statement above, this paper puts forward a resistance surface model of space-economic process, so as to show the spatial distribution of the resistance and the trend of movement in economic process of an area. This model is a great revelation to the research on the movement of element flows and strategic programms in regional development. Exemplified by the case study of Zhe-Min-Gan bounding area, this paper testified the model's function in order to explain why the economy is held up in border areas among provinces, and reveals its practical significance in the revelation of regional developing programmes.
