摘要：

选取以重庆市主城区为中心,包括其周边的几个区、县的平行岭谷区为研究区,探讨当前的“二环八射”道路格局下建设用地演变特征及道路格局对建设用地扩展演变的驱动机制。结果表明,研究区逐步形成的“二环八射”高速道路格局突破了平行低山岭谷的阻隔, 1988~2010年,建设用地的分布与扩展存在由内向外的圈层梯度效应,有着沿高速公路沿线集中分布的趋势。各高速沿线建设用地扩展与各高速路的通车时间有一定的正相关关系,同时受沿线地形因素和区位因素的影响。

Abstract:

Researches on the influence of the fast developed road network in recent years upon land use and landscape pattern change in the region with original obstructed transportation can provide reference for future land use. In this article, the study area, including Chongqing metropolitan region and several counties around it, is located in the western paralleled ridge-valley area, which is chosen as an example to explore how the road pattern being developed gradually drives the evolving of construction land in this area through comparing the evolution pattern and proportion of construction land. The image data of TM in 1988, 2001, 2007 and China′s environmental satellite image in 2010 were chosen as a datum source. The results show that the “two ring and eight radial freeway” road pattern formed individually in recent 20 years has broken the obstruction of mountains distributed in the study area with paralleled ridge and valley area, therefore, from 1988 to 2010, the expansion intensity of construction land has increased with a gradient effect from inside to outside, and the construction land is grouped mainly along the highway. The evolving models of construction land could be summed up: first, the urban land showed markedly a kind of ‘sphere-type’expansion mode in the center of the study area; second, the expansion of construction land behaved as an agglomeration and group development mode in the middle of the study area; third, the construction land behaves as a leap frogging or scattered expansion in the outer sphere of the study area. At the same time, the evolving of construction land is influenced by the run time of each highway and the topography and locational factor along highways. These results indicate that the road pattern play a significant role in the rapid expansion processes of the construction land, and the road network has an obvious routeway effect upon the land use changes in the study area.
