摘要
以兰新铁路为辐射轴,以100km为辐射半径所形成的辐射范围内的县级行政单元为研究对象,选取10项经济指标,综合运用SPSS、GeoDA和ARCGIS 9.2,对于兰新铁路辐射带经济空间差异进行分析发现:经济实力在全区平均水平之下的占多数,相似区域在空间上呈集聚趋势;按照经济实力得分,把县级行政单元分为经济发达地区、经济较发达地区、经济中等地区、经济欠发达地区、经济不发达地区;从数量上看,县级行政单元经济发展等级基本呈现"金字塔型";经济发展存在不均衡现象;经济实力在东南—西北方向呈现明显的"U"型,在西南向东北、东向西、北向南方向上都呈现递减趋势,但变化不明显;经济实力的热点区在乌鲁木齐市和兰州市,盲点区在兰新铁路辐射带甘肃段的东南部。最后,从自然地理条件、区位因素、发展战略、区域相互作用等方面分析了区域差异的原因。
Based on the eighty-two counties data of relative economic indexes,which lie along Lan-Xin Railway belt radiated within 100 km radius,this paper calculates the general scores of counties economic strength,and then analyzes the spatial differences of county economic strength in Lan-Xin Railway Radiation Belt by means of spatial analysis provided by ARCGIS 9.2 and GeoDA.The result that the economic strength of fifty-six counties is smaller than the average level,shows that weaker counties takes bigger portion,and it is spatial concentrated for those similar units;Accord to the general scores of counties economic strength,the counties in Lan-Xin Railway Radiation Belt can be divided into five types： the economic developed area,the comparatively developed area,the medium area,the undeveloped area and under-development area;From the number of county administrative units,the rank of county economy basically presents ＂pyramid＂;The economic development exists unbalance phenomenon;The economic strength significantly presents ＂U＂ in southeast to northwest,it shows decreasing trend from the southwest to northeast,east to west and north to south direction,but the trend is not significant;Lanzhou city and Urumqi city lie in the hot zone,blind spot area mainly distributes in the southeast part of the Lan-Xin Railway Radiation Belt.Finally,this paper analyzes the reasons of regional difference in geographical conditions,location factors,development strategies,and regional interactions.
