Heterogeneous effects of climate change and human activities on annual landscape change in coastal cities of mainland China

Landscape degradation and fragmentation has taken place across the coastal area of China over the past decades due to complex interactions between natural and anthropogenic processes, which results in various negative environmental and ecological consequences. Therefore, understanding of the spatio-...
