摘要
长白山独特的地质和地理条件,形成了特有的自然景观,植被垂直带谱在亚洲具有代表性。通过1977年MSS、1985年TM及1999年TM三期遥感影像,结合实地调查建立解译标志,进行分类并计算景观指数,分析了长白山地区近30年来的景观结构变化。分析表明：从景观面积变化率来看,1977-1985年间,水体、苔原、居民点、针叶林和草地的面积减少,耕地和针阔混交林的面积增加显著,阔叶林、岳桦林、道路、裸地增加;1985-1999年间,水体、裸地、针阔混交林和阔叶林的面积减少,其他类型面积增加。景观格局变化表明,人为活动对景观格局产生的影响,已成为景观格局变化的主要驱动因子。
The Changbai Mountain has a special landscape in its particular geological and geographyical conditions,particularly in its vertical vegetation zone,which is typical in Asia.According to the spans image of MSS in 1977 and TM in 1985 and 1999,we have established the interpretation symbols in combination with the field survey,and analyzed the landscape structure changes for 30 years in this area by computing the landscape index.The result indicates that the water,tundra,residential sites,needle-leaved forest and brass were decreased from 1977 to 1985;while the plantation and the coniferous and broad-leaved mixed forest obviously increased;and the broad-leaved forest,betula ermanil forest,road and bare soil also increased.During 1985 to 1999,the water,bare soil,coniferous and broad-leaved mixed forest,broad-leaved forest reduced,the rest landscape types increased in this area.The changes of landscape pattern and process indicate that the effect for landscape pattern was caused by the human＇s existence become a mainly driving factors.
