摘要
以人均GDP为主要测度指标,采用GeoDA软件提供的空间分析方法与统计分析方法,探索2000-2007年嘉陵江流域经济差异的时空格局和空间作用类型。结果表明:嘉陵江流域人均GDP的绝对差异不断增大,相对差异逐渐缩小。流域经济的总体差异表现为中游地区差异>上游地区差异>下游地区差异,中游地区差异是导致流域经济总体差异的主要原因;其中上游、下游及区间差异不断扩大,而中游地区经济差异不断缩小。经济发展的高水平区域向主要交通干线聚集,而流域经济发展的空间关联效应不强,"马太效应"严重,建立"天水经济中心"和"川东经济中心",可增强上游和中游经济实力,对缩小流域经济差异具有重要意义。
Based on the index of per capita GDP,spatial-temporal pattern and spatial interaction types of economic disparities in Jialing River Basin during 2000-2007 have been probed into by the method of combining spatial autocorrelation analysis and statistic analysis.The conclusions are as follows：the Absolute difference of per GDP is increasing constantly,while the relative difference is gradually decrease.The total difference in Jialing River Basin shows that the difference in the upstream is the largest;and the differences in the middle reaches are larger than the downstream′s;among the total differences,the differences in the middle reaches account for the largest proportion,and the change trends are in line with the total differences.From the other side,the differences in the upstream,downstream and the segment among the river basin become larger and larger,while the differences in the middle reaches is decreasing.The counties with high economic level have extended along the direction of main traffic lines,but the spatial association is weak in the study area,the ＂Matthew Effect＂ is seriously taken on in the Jialing River Basin.In order to enhance the economic strength of the upper and middle reaches in Jialing River Basin,the economic center in Tianshui and in the east of the Sichuan Province should be set up,which is of great significance to narrow the economic disparities.
