摘 要:基于280多个县(市)的18项社会经济发展评价指标,采用层次分析法构建定量化评估体系,并借助Arc GIS空间分析技术,分析了黄土高原区县域发展的空间差异和变化特征。结果表明:2000年黄土高原区社会经济发展水平普遍较低,综合发展指数在1.09~3.79之间,空间上表现为西北部和东南部高而中部较低的格局,区域间差距较小;之后的11年,综合发展指数均值由2000年的2.06上升到2011年的3.03,社会经济发展水平显著提高,但区域发展速度差异明显,西北部迅速,西南部迟缓;到2011年,西北部综合指数达5.18~7.05,东部和中部在3.01~4.89,西南部仅1.71~2.99,区域间发展水平差距拉大;县域社会经济发展具有明显的空间集聚性,即高值和高速区聚集,低值和低速区聚集,区域中心城市的辐射带动作用不强。应加强区域合作和对发展滞后县域的扶持力度。Based on 18 evaluation indexes that stand for socioeconomic development level with the more than 280 counties(or cities), this paper uses AHP to build quantitative evaluation system, and with the ArcGIS spatial analysis technique to analyzes the spatial differences and changes at county-level in the Loess Plateau. The results indicated that: The socioeconomic development levels were generally low in 2000, and the development indexes were between 1.09 and 3.79, higher in the northwest and southeast parts than that in middle part of the Loess Plateau. During the following 11 years, the Loess Plateau got a rapid development, with the regional mean index increased to 3.03 in 2011 from 2.06 in 2000. However, the development was not balanced: the counties in the northwest parts showed a much faster growth rate than the counties in the southwest parts, and thus expanded the development gaps between countries. In 2011, the integrated development indexes were 5.18-7.05 in northwest counties, 3.01-4.89 in eastern and central counties, and only 1.71-2.99 in southwest counties. The socioeconomic development has a significant spatial agglomeration characteristic, i. e., the counties with higher development level and speed tended to be gathered, and similarly, the counties with lower development level and speed tended to be gathered. The regional central cities did not show a strong promotion to the development in the surrounding counties, reflected that the inter-regional collaboration was weak. To promote future development, it should strengthen the regional cooperation and increase support to backward regions to narrow the development gap between countries.
