| 摘 要： | 根据1974、1994和2002年三个时段卫星影像,将土地覆盖类型划分为针叶林、针阔叶混交林、落叶阔叶林、灌丛、草地、裸地和水体7个类型。研究发现,九寨沟森林面积、特别是针叶林面积减少,各景观类型破碎化程度也在增大。与1974~1994年间森林丧失平均速率相比,1994~2002年间森林丧失速率明显放缓。第二期灌丛面积平均增长速率是第一期的3.5倍。随着生境破碎化的加剧,许多珍稀保护生物的前景变得难以预测,应以审慎的态度来对待所谓的生态旅游。

| Abstract: | The protection effect of Jiuzhaigou Nature Reserve has received considerable attention,especially in view of its stimulating tourism after the 1990s.Remote sensing data from 1974,1994 and 2002 were chosen for the analysis of this reserve,and landcover was divided into 7 types,i.e.Conifer Forest(CF),Conifer and Broadleaf Mixed Forest(CBM),Deciduous Broadleaf(DB),Shrubland(SL),Meadow(MD),Bareland(BL) and Water Area(WA).We find that the quality and quantity of the forest in Jiuzhaigou Nature Reserve continues ... |
