摘要：China's coastal wetlands have an extensive spatial span and a long coastline, which causes very significant regional differences in the coastal geographical environment. Compared with traditional field surveying, multi-source spatio-Temporal data can quickly collect coastal landscape pattern and dynamic evolution information, thus saving a lot of labor, material resource and time cost. In this study, time series high resolution image and luminous thematic data (2015-2019) were adopted for the characteristics of human activity and spatial dynamics assessment in China's coastal zone. The results demonstrated that the proportion of man-made landscape types in the China's coastal zone has exceeded 50%, and indicates a steady growth trend with an average annual growth area of 308.35 km2. In the past five years, the natural land has been continuously transformed into the artificial land. The different development behaviors have caused the spatial differentiation of landscape pattern in coastal zones. The coastal landscape dynamics of China's coastal zones is bounded by the Hangzhou Bay. The comprehensive dynamic attitude in the north is higher, while the comprehensive dynamic degree in the south is concentrated in Hangzhou Bay, Zhejiang, Fujian, Pearl River Delta and Hainan Island. The spatial characteristics of the radiation brightness demonstrate that the change of human activities in the coastal zone is universal in urban and non-urban areas throughout the past five years. The spatial correlation between noctilucent radiation and landscape change in coastal zone is significant year by year, which concludes that human activity is the main driving force of coastal landscape pattern evolution. ?
