不同建筑密度下城市森林景观逆破碎化趋势
Landscape Defragmentation Trends of Urban Forests under Different Building Densities
摘要
Abstract
Based on Quick Bird images and geographic informational system, responses of landscape fragmentation trend to the urban building density and gradients of urban forest coverage were analyzed. The results showed that landscape fragmentation status of urban forests was distinctly influenced by urban building density. Dense urban areas were sensitive regions with high level of landscape fragmentation of urban forest. It undulately responded to the increase of urban forest coverage. Ten to fifteen per cent of forest coverage was the undulating range of landscape indices of urban forest. Landscape fragmentation of urban forest in less dense area decreased steadily with the increase of forest coverage. Twenty to thirty per cent of forest coverage was rapidly changing range of landscape indices of urban forest. The trend of landscape defragmentation of urban forest was preliminarily probed under the variation of landscape fragmentation.关键词
