利用长春市中心城区2003年、2013年土地利用现状图,运用廊道效应原理与Arc GIS空间分析功能,揭示了交通系统"快速化"背景下长春市各级交通路线对城市功能用地演替的作用效应关系。研究发现:轻轨、主干路、快速路对商服用地的吸聚效应依次增强,快速路沿线商服用地主要用于专业化市场建设,轻轨沿线商服用地用作综合性商场开发;快速路对沿线居住用地吸聚强度大于主干路,轻轨对沿线居住用地具有近距离排斥效应;在市中心区,快速路、主干路、轻轨对工业用地的排斥强度依次增强,但随着由中心至外围的过渡,快速路的排斥效应将转化为吸聚效应。各级交通路线对沿线城市功能用地作用效应的差异性,一定程度上推动了长春市城市地域结构的演变。
The land status maps covering the years 2003- 2013 provide the main data for this article. With the help of corridor effect theory and Arc GIS analysis tools, the paper studies the relationship between different traffic routes and urban land use against a backdrop of a rapidly expanding traffic system. The research revealed the following: light rail, trunk roads and expressways attract commercial land usage along traffic routes, and this, in turn, intensifies and exacerbates that attraction. Commercial land along expressways is mainly used for the construction of specialized markets. Commercial lands along light rail routes are used for the construction of comprehensive shopping malls. Trunk roads going to residential areas have less commercial appeal. Similarly light rail routes to residential areas tend to have a repulsion effect on commercial usage. In city center areas, expressways, trunk roads and light rail exclude industrial lands along traffic routes, and this, in its turn, further intensives the exclusion effect.However, with the transition from the center to the periphery, the current repulsion effect of expressways will be converted to an attraction effect. These differences in the effects of traffic routes on urban land use contribute to the evolution of Changchun city's urban area structure.
