兰州市经济发展潜力空间格局分析

Analysis on the Spatial Pattern of Economic Development Potential of Lanzhou

构建评价指标体系,运用熵权逼近理想解的排序法(technique for order preference by similarity to ideal solution,TOSIS)、Moran’s I和协调度模型,从乡镇(街道)尺度研究兰州市经济发展潜力的空间差异、空间集聚以及影响因素。研究结果可为相关政府部门统筹兰州市可持续发展提供科学参考。

Building evaluation index system,using entropy weight TOSIS,Moran's I and coordination degree model, this paper analyses the spatial difference,spatial agglomera- tion and influencing factors of Lanzhou^s economic develop- ment potential from the scale of township (street).The re- suits show that:1)The economic development of pulling power,traffic location supporting force and land resources security force in the township scale show different spatial distribution characteristics.2)The potential of economic de- velopment differs between urban and rural areas,the district (county)government in the streets or town potential is sig- nificantly higher than the surrounding area,playing a certain role in driving.3)The potential of economic development has a significant spatial clustering,which includes three types of aggregation,LL,LH and HH.Among them,H.H is distributed in Xigu district,Anning district,most of QiIi- he district and Chengguan district streets.LL dots in the pe- ripheral towns of Yuzhong county.4)Economic develop- ment potential coordination is poor,the vast majority of vii-lages and towns (streets)are subject to the constraints of traffic conditions or land resources security.The central city has a higher degree of urbanization,traffic conditions are more superior,the future development is mainly limited by the ability of land resources security.The results can provide a scientific reference for the ments to co-ordinate the Lanzhou. relevant government depart- sustainable development of Lanzhou.
