Abstract:As a hot topic in Landscape Ecology study, ecological connectivity is playing very important roles in wildlife dispersal, ecosystem energy flow and disturbance spread. Ecological connectivity is the degree to which the landscape facilitates or impedes the movement of ecological flows among resource patches. Ecological connectivity mainly based on percolation theory and graph theory, describes the landscape structure and function by using the quantified methods of experiments, models and indices. Ecological connectivity is applied broadly in the natural landscape and urban landscape and is meaningful to the biological conservation and open urban area planning. In the paper, the theoretical basis, research method, findings and applications, ongoing prospects of the ecological connectivity, are reviewed so as to promote the further development in this research field.
