地球大数据支持下的城市可持续发展评估：指标、数据与方法

he sustainable development of cities is the key to achieving the United Nations 2030 Sustainable Development Goals (SDGs). There have been numbers of studies on urban sustainable development assessment, but the existing indicators are usually based on traditional statistical data, which makes urban sustainable development assessment limited in global city assessment and comparison. Big Earth Data can overcome the problems of traditional data statistics such as inconsistent statistical caliber, incomplete statistical information, and difficulty in obtaining data. With its macroscopic, dynamic, and diverse advantages, it can provide new assistance for urban sustainable development assessment. Based on the research on sustainable development of cities worldwide, this study sorts out the SDG 11 and other goals related to urban sustainability, and discusses the possibility of Big Earth Data, such as remote sensing data and the Internet big data, in the urban sustainable development evaluation. This study hopes to provide a scientific reference for the sustainable development of cities. The sustainability indicators using the Big Earth Data has realized the integration and utilization of multi-source information, which will help to achieve more quantitative, real-time, and detailed evaluation for urban sustainability.
