This paper selected nine influencing factors aspect, air temperature, normalized...

In recent years, Northwest China has experienced rapid land-use transformation and urbanization. Land-use carbon emissions associated with human activities are an important cause of climate change. However, the sources sinks change in arid zone watersheds need further study. This study focuses on Bosten Lake employs a combination top-down bottom-up methods to assess spatial temporal evolution source sink balance under land use changes identify areas high emission risks. The key discoveries...

Analyses of landscape patterns, analyses land-use/land-cover evolution characteristics, and a driving force analysis during the expansion urban agglomerations can assist in solving ecological environmental problems; moreover, these tools provide reference for land-use structure optimization planning. In this study, rapid urbanization agglomeration small- medium-sized cities were evaluated; specifically, northern slopes Tianshan Mountains (UANSTM) was assessed. Using multi-period (1995, 2000,...

Accurately capturing the changing patterns of ecological quality in urban agglomeration on northern slopes Tianshan Mountains (UANSTM) and researching its significant impacts responds to requirements high-quality sustainable development.
