Until 2018, China has accounted for nearly 1\/5 of global megacities. Understanding their urbanization processes is of great significance. Given the deficiencies of existing research, this study explored the interannual urbanization process of China\u2019s six megacities during 2000\u20132018 from four aspects, namely, the basic characteristics of urban land expansion, expansion types, cotemporary evolution of urban land\u2013population\u2013economy, and urbanization effects on the local environment. Results indicated that (1) urban lands in China\u2019s six megacities increased by 153.27%, with distinct differences across megacities; (2) all of six megacities experienced the expansion processes from high-speed to low-speed, but they varied greatly in detail; (3) the speeds of urban land expansion in China\u2019s megacities outpaced the population growth but lagged behind in GDP increase; and (4) urbanization has triggered an environmental crisis, which is represented by the decline in vegetation coverage and the increase in land surface temperature in newly expanded urban lands. This study enriched the content of urbanization, supplemented the existing materials of megacities, and provided a scientific reference for designing rational urban planning.<\/jats:p>","DOI":"10.3390\/rs11182138","type":"journal-article","created":{"date-parts":[[2019,9,13]],"date-time":"2019-09-13T10:32:41Z","timestamp":1568370761000},"page":"2138","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Assessing Interannual Urbanization of China\u2019s Six Megacities Since 2000"],"prefix":"10.3390","volume":"11","author":[{"given":"Sisi","family":"Yu","sequence":"first","affiliation":[{"name":"Aerospace information research institute, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}]},{"given":"Zengxiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Aerospace information research institute, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Fang","family":"Liu","sequence":"additional","affiliation":[{"name":"Aerospace information research institute, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing 100101, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8281-5224","authenticated-orcid":false,"given":"Xiao","family":"Wang","sequence":"additional","affiliation":[{"name":"Aerospace information research institute, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Shunguang","family":"Hu","sequence":"additional","affiliation":[{"name":"Aerospace information research institute, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing 100101, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,13]]},"reference":[{"key":"ref_1","unstructured":"United Nations (2019).
