Research on the Development of Urbanization in Yangtze River Economic Belt Based on Nighttime Light Remote Sensing Data

摘要

Urbanization development information is an important factor in the spatiotemporal evolution of human activities. It is of great significance to grasp the dynamic information timely of long time series urbanization in a large spatial scale for policy-making of urbanization development. In this paper, a method based on extracting the city center of gravity and speed of development based on nighttime light remote sensing data (Defense Meteorological Satellite Program's Operational Line-scan System (DMSP-OLS) and Visible Infrared Imaging Radiometer Suite Day/Night Band (VIIRS-DNB)) from 1992 to 2018 is proposed to reveal the law of urban development, which has been used in Yangtze river economic belt successfully. The conclusion can indicate that the use of nighttime light remote sensing data can provide theoretical basis and technical support for the scientific management and planning of urbanization development.
