摘　　要： 研究目的:以"高分一号"遥感影像为主要数据源,探讨规划区内道路交通对建设用地空间格局的影响特征。研究方法:以从化中心城区规划区道路为例,运用道路密度指数、长度—半径分维、景观破碎度、威弗指数等模型,结合GIS空间分析方法。研究结果:从化中心城区规划区,(1)道路网络分形特征较明显但道路完善度较低,建设用地用途宏观布局呈圈层分布特征;(2)综合道路最大服务范围最大,一、二级道路影响范围次之,三、四级道路逐级缩小;(3)建设用地的主要用途类型数量与道路距离整体上成反比,综合道路周围以三种用途为主,一至四级道路两侧以不同的两种用途为主;(4)高分遥感影像利于乡道提取和建设用地用途判读。研究结论:道路交通对规划区内建设用地用途格局具有导向作用。 The purpose of this paper is to analyse the impacts of traffic road on the spatial pattern of construction land in urban planning area by using satellite imagery of the high-definition earth observation satellite ＂Gaofen-l＂. Taking the road of central urban planning area of Conghua for an example, we employ methods of GIS spatial analysis and landscape indexes （such as road density index, length-radius fractal dimension, landscape fragmentation degree and weaver index） to test the relationship bewtten traffic road and construction land.The results are obtained as follows. Firstly, the fractal characteristic of road network is obvious while the improvement degree is low in central urban planning area of Conghua. The macro layout of the utilization of construction land shows layer distribution. Secondly, the relatively independent influence range of the integrated road is the maximum, followed by the first and second grade roads and declined from the third grade roads to the fourth roads. Thirdly, the number of main utilization types of construction land is inversely proportional to the distance from the road. There are three main utilization types around the integrated road, yet there is a different combination of two main utilization types on both sides of grade roads from the first to the fourth. Furthermore, high-resolution remote sensing image is conducive to the extraction of rural road and the interpretation of utilization types of construction land. This paper suggests that traffic road has the guiding function to the utilization pattern of construction land in the planning area.
