The ecological and environmental conditions in semiarid areas are closely linked to landscape dynamics. This study examined the seasonal vegetation activities of landscape classes and dynamics in the Loess Plateau in North Shaanxi Province, China. Landscape dynamics were studied by comparing Landsat images in 1987 and 2007, and classified as landscape transitions, landscape variations and uncha...

Wetlands are very sensitive to ecosystem changes, so integrated analyses and modeling of their process dynamics as well as their interaction with other hydrologic and ecological components provide valuable information for impact assessment. However, since wetland processes are complex, research methods aiming to improve the understanding of wetland dynamics in a landscape perspective must compr...

The relationship between landscape patterns and functions is the central research theme of landscape ecology and forest management. This study assesses the interactive relationship of landscape heterogeneity with the carbon stock of urban forests in the city of Xiamen, Fujian Province, China, using spatial and statistical analyses. The objectives of this study are to explore the most appropriat...
