【摘要】 采用景观格局指数分析方法,从景观水平和景观要素类型两个层次上,对比分析了武夷山市景观格局的空间变化,得出该区域在研究时段内景观整体破碎化程度降低、景观异质性增强,同时森林景观面积减少、优势度下降的结论。这种景观空间变化将会降低区域景观在维持生物多样性、保持水土、以及固碳等方面的生态功能。更多还原

【Abstract】 The spatial changes of landscape pattern in Wuyishan Ctiy on the landscape level and the class level were analyzed, with the spatial analysis of landscape pattern. It showed that the landscape fragmentation degree decreased while the landscape heterogeneity increased. At the same time, the area of forest reduced sharply, and the dominance index of forest declined. It can be concluded that these changes can impair the functions of ecosystem on biodiversity maintaining, soil and water conservation, and carbon fixation.更多还原
