| 摘 要： | 以高黎贡山1974年MSS遥感影像、1987和1997年TM遥感影像和2006年IRS遥感影像以及地形图等相关资料为基础数据,在GIS技术支持下,结合景观生态学原理,从景观格局、森林景观动态变化特征方面对云南高黎贡山南段进行了研究。结果显示,研究区景观的破碎程度随时间推移而增大,景观异质性程度降低,土地利用逐渐趋于单一化,土地的开发程度增加,人类对景观的干扰程度加强;各类森林景观交错镶嵌,分布活跃且形状复杂,分化程度高,具有较高的森林景观异质性和丰富的景观多样性。

| Abstract: | On the basis of remote sensing images of MSS in 1974,TM of 1987 and 1997,and IRS of2006,and topography map,supporting with GIS and coupled with landscape ecology theory,of the south Gaoligong Mountain in Yunnan province was researched in landscape patterns and dynamic change characteristics. The results indicated that with time going on,the fragmentation of landscape increased,heterogeneity of landscape decreased,and the land use gradually tended to be simplification. It also implied that with land development speeded up,the interference of the human imposing upon landscape was enhancing. The distribution and structural shape of these landscape spots was complex. In other words,the study area had high heterogeneity and landscape diversity. |
