基于DMSP/OLS夜间灯光数据的城镇化进程及格局研究 ——以杭州市为例
A study of urbanization progress and spatial pattern using DMSP/OLS nighttime light data:A case study of Hangzhou City
摘要
Abstract
The DMSP/OLS nighttime light ( NTL ) data provide an effective approach to characterizing the urbanization progress of cities, especially its spatial-temporal changes. In this paper, the authors combined the DMSP/OLS NTL data with the social economic statistics to examine the urban expansion of Hangzhou City, the capital of Zhejiang Province in eastern coastal region of China, during the period of 1992―2013. The relationship between urban expansion and traffic lines were also detected with the concept of landscape pattern and patches. The results show that the urbanization in Hangzhou City before 2000 was quite slow, and there existed an accelerated process since 2000 due to the development of economy, with the urbanization region also converted from central downtown to other areas along with the process. Further research indicates that the urbanization process in Hangzhou City has a great relevance with transportation in terms of direction and pattern, which might be attributed to the terrain and local condition. It is a novel attempt to investigate the urbanization of Hangzhou City on the basis of the DMSP/OLS NTL data and concepts of landscape, which would provide a significant guideline for the urban planning and development.关键词
