基于高分辨率遥感数据的城市居住单元交通环境质量评价——以厦门市为例

居住单元是与人们生活密切相关的社区范围，其交通环境的优劣是衡量居住单元环境好坏的重要标准之一。高分辨遥感影像的高空间分辨率特点为我们提供了研究居住单元交通环境的可能性。本文从区域交通环境、路网可达性出发，对城市居住单元交通环境质量的遥感评价方法进行了研究，根据高分辨率遥感影像的特点构建了居住单元交通环境的多级指标评价体系，并对厦门市的50个居住单元进行了评价分析。实验表明，利用高分辨率影像进行城市交通环境质量评价是一种成本较低，简便可行的方法。

THE ASSESSMENT OF TRAFFIC ENVIRONMENTAL QUALITY OF THE URBAN RESIDENTIAL UNIT BASED ON HIGH RESOLUTION REMOTE SENSING: A CASE STUDY OF XIAMEN CITY

The urban residential unit is intimately related to people's life,and the traffic environment of a residential unit constitutes a key standard for the environment assessment of the unit.The spatial resolution of the high-resolution remote sensing image makes it possible to study the traffic environment on the scale of the urban residential unit.According to characteristics of the high-resolution image,a multi-level index system for the assessment of traffic environment of urban residential units was constructed,which took into account the traffic environment and road accessibility.In this paper 50 representative urban residential units in Xiamen City were chosen and all the indices mentioned above were computed and further analyzed.The results indicate that the utilization of the high resolution image for the assessment of city traffic environment quality is an economical,simple and feasible method.
