一个地区发展的结果往往直接体现在物质财富的生产和积累上。因此可以从资源角度出发,以资源转化为视角,以区域物质财富为着眼点来反映区域发展进程。论文从基础设施水平、交通通达度、经济发展水平三方面,构建物质积累指数模型;运用GIS技术和数理统计方法,以2006、2007、2008三年数据为例,计算关中-天水经济区分县(区)物质积累指数,系统评价经济区物质积累水平。结果表明:①除个别县(区)外,关中-天水经济区各县(区)的物质积累指数呈现出逐年增加的趋势,但增幅都不大,只有7个县(区)的增长幅度超过了4%,增长最快的并不是各市辖区,而是物质积累指数处于中等水平的部分县(区);②经济区物质积累指数中心3 a均位于咸阳市礼泉县境内,位置变化不大;③关中地区的物质积累指数普遍高于商洛及天水地区,并且呈现出东西方向的狭长走势。

Regional development is a course of accumulation based on many factors, which is directly related to resources utilization and conversion. And material possession production and accumulation embody the outcome of regional development. Thus, focusing on material possession, regional development can be evaluated from resources and perspective of resources conversion. The material-based development index model was established based on the infrastructural level, transportation accessibility and economic development level in this paper. By using GIS technology and mathematics statistics methods, this paper then calculated the material-based development of each county of Guanzhong-Tianshui Economic Zone in 2006, 2007, 2008, and systematically evaluated the material-based development of the Economic Zone. The result showed that: 1)Except several counties, the material-based development index of Guanzhong-Tianshui Economic Zone showed a rising trend, but the growth rate is not great. Growth rate of only seven counties exceeded 4%. The fastest-growing areas are not the areas under the jurisdiction of the cities, but are the counties with material-based development index being in the moderate level. 2)The center of material accumulation index of the Economic Zone is in Liquan County of Xianyang in 2006, 2007 and 2008 with little change in geographic location. 3)The material-based development index of Guanzhong is generally higher than that of Shangluo and Tianshui, showing a narrow east-west trend.
