摘要:

选取老工业基地吉林省的9个主要城市为研究对象,运用加权平均旅行时间指数对各城市的可达性水平进行测度,采用改进的引力模型测算出各城市的经济联系强度,并依据经济联系的隶属度来确定城市经济联系方向,结合引力断裂点模型和GIS空间分析技术对吉林省城市经济联系的空间范围进行界定。研究结果表明:吉林省可达性水平较高地区主要集中在中部地区,形成以长春为中心,由内向外呈逐步降低的“中心-外围”圈层式空间格局;城市经济联系强度地域分布呈显著差异,中部城市的经济联系强度大于西北部和东部城市的经济联系强度,且交通可达性与经济联系强度具有显著的相关性;在中部地区形成了1个以长春市为中心,向外辐射的“同心圆”式的经济联系密集区,东部的延吉市与长吉地区经济联系密切,东南部的通化市和白山市经济联系紧密,吉林省城市经济联系符合距离衰减规律。

Abstract:

Taking main 9 cities (Changchun, Jilin, Siping, Liaoyuan, Songyuan, Baicheng, Baishan, Tonghua and Yanji) in Jilin Province, which belong to the northeast old industrial base of China as examples, , this article used the weighted mean travel times as indicators by the improved gravity model to calculate the urban accessibility and the economic linkage intensity among the 9 cities. Then, the economic linkage subordination degrees was employed to indentify the economic linkage direction of the cities. Moreover, the ranges of economic linkage scales of cities in Jilin Province were defined by use of gravity breakpoint model and GIS spatial analysis. The results showed that the accessibility level of central area is higher than other areas in Jilin Province, the circle-type spatial pattern of the accessibility level that reduces gradually from Changchun to outside has emerged, the disparity of economic linkage intensity among cities in Jilin is remarkable and the middle cities have larger economic linkage intensity than the northwestern and eastern ones. The traffic accessibility is highly related to the economic linkage intensity, and the economic linkage concentration area has been formed which is in the middle cities with an outward radiating “concentric circle” shape and Changchun as its center. In the east, Yanji has larger economic linkages with the region of Changchun and Jilin, while, in the southeast, Tonghua has larger economic linkages with Baishan. The urban economic linkages of Jilin Province conform to the law of distance attenuation.

Key words: accessibility, economic linkage intensity, gravity model, spatial patterns, Jilin Province
