Dynamic monitoring and characteristics analysis of built-up lands in china based on remote sensing and GIS technology

摘要

In the last two decades, the rapid economic development and constant rise of urbanization level and relevant policies resulted in a dramatic expansion of built-up lands in China and in different expanding stages. The present study monitored built-up land information by using remote sensing and GIS technology, and analyzed its evolution process. This study will be beneficial in understanding the characteristics of built-up land growth and sustainable development of China.
