【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]:Taking the main urban area of Chongqing as the center, including several districts around it, and the parallel mountain valley of county as the research area, This paper probes into the characteristics of the evolution of construction land and the driving mechanism of road pattern on the expansion and evolution of construction land under the current "two-ring and eight-shot" road pattern. The results show that the pattern of "two rings and eight projectiles" highway formed gradually in the study area broke through the barrier of parallel low mountains and valleys from 1988 to 2010, and the distribution and expansion of construction land had a gradient effect from inside to outside. There is a trend of concentration along the highway. There is a positive correlation between the expansion of construction land along the highway and the opening time of each highway, and it is also affected by the terrain factors and location factors along the highway.
