Different effects of human settlements changes on landscape fragmentation in China: Evidence from grid cell

Exploring how human settlement expansion affects landscape fragmentation is particularly critical to understanding the complex interactions between human activities and landscape functions, patterns, and processes. Here, we use recently developed built-up data and land use data to characterize this...

Findings suggest that the mean built-up ratio has enlarged three-fold in the past 40 years. The landscape pattern has become increasingly fragmented.

Contrary to traditional perception, the influence of settlement growth on landscape fragmentation in large cities is not as pronounced as that of small and medium cities.
