急剧城市化背景下森林破碎化模式分析——以浙江余杭区为例
Assessment of Forest Fragmentation Driven by the Intensive Urbanization——A Case Study of Yuhang District
摘要
Abstract
Based on the land use data of the years of late 1980's, 1995, 2000 and 2008, a forest fragmentation model coupled with spatial metrics was applied to characterize the status and trends of forest fragmentation in Yuhang District, Zhejiang Province, China. A statistical link between forest fragmentation and urbanizatian level in the fear of 2008 was furthe constructeal to provide an insight and implication for forest spatial configurations over medium and small cities. The results suggested that forest coverage increased slightly over the time period of lale 1980s to 2008 but the interior condition decreased accompanied with an increase for perforated, patch, edge and transitional components, indicating an accelerated forest fragmentation in the study area. Anthropogenic disturbances imposed on the forests were far greater than natural disturbances. Specifically, the strongest contribution to forest fragmentation was identified as agricultural land uses, followed by urban sprawl and natural land cover changes. For the land use data of the year of 2008, an exponential correlation y = 0. 115 5e0.0429χ, with the determinant coefficient R2=0. 55, was simulated to link the fragmentation severity with the urbanization level.关键词
