摘要: [目的] 通过对景观格局动态变化分析为长白山地区景观资源有效保护提供依据。[方法] 以吉林省长白山地区1991年、1999年、2010年的3期TM遥感影像为数据源,通过RS解译、景观特征指数计算,结合自然要素与人为干扰,具体分析了长白山地区森林景观格局的变化规律。[结果] 分析结果表明:近20年间,研究区景观斑块面积和数量发生明显变化,除针叶林外其他各景观斑块数量大幅增加,研究区景观动态度变化显著,针叶林、阔叶林、针阔混交林的面积减少,而灌草丛、耕地、高山植被、建设用地、水体面积增加。研究区景观破碎程度和异构性较高。景观分维数较小,形状较简单,且20年来变化不大。连通程度较高的优势斑块类型减少,连通性变差,景观格局向密集化发展。[结论] 该研究区景观斑块呈明显的破碎化发展趋势,表现出明显的脆弱性。

Abstract: [Objective] The aim of the study was to provide a scientific basis for effective protection of landscape resources in Changbai mountain by analyzing landscape pattern dynamic change. [Method] Based on the TM remote sensing image of Changbai mountain in 1991,1999 and 2010,Landscape characteristic indexes were calculated by RS interpretation in consideration of natural and human influence.Then the dynamic change of forest landscape pattern in Changbai mountain was analyzed. [Results] In the last 20 years,the area and quantity of landscape patches as well as landscape dynamic have changed obviously.The number of landscape patches substantially increased except for coniferous forest.The areas of coniferous forest,broad-leaved forest and mixed broadleaf-conifer forest decreased while shrub grassland,farmland,alpine vegetation,construction land and water body area increased.The study area had relatively high landscape fragmentation and heterogeneity.However,landscape fractal dimension was low and landscape shapes was simple,with slight change over the last 20 years.The decrease in dominant patches with relatively high connectivity lowered landscape connectivity and increased densification of landscape pattern. [Conclusion] There will be fragmental trend in landscape patches,with high vulnerability in this area.

Key words: Changbai mountain, forest, landscape pattern, landscape index, remote sensing
