Study on the Livability of Urban Environment: A Case Study of Built-Up Area in Qingdao, China

The acceleration of urbanization in China makes people more concerned about the livability of urban environment. The concept of 15-minute living circle is gradually applied to land space planning to provide guidance for the construction of high-quality community to serve citizens. This paper used multi-source data of remote sensing imagery and POI to build Qingdao's urban convenience index from the perspectives of travel, shopping, health care, catering, entertainment, education and so on, so as to evaluate the livability of urban life. The results show that areas with higher convenience of living circle are located in the regions with flat terrain. The highest convenience degree distributes along the East and West Coast of Jiaozhou Bay, almost all of which were located in traditional old urban districts. The urban livability assessment from the perspective of convenience of 15-minute living circle can provide guidance for city and landscape planning.
