摘　　要：为解决天目山国家级自然保护区毛竹Phyllostachys pubescens林扩张与生物多样性保护矛盾日益尖锐的问题,应用遥感和地理信息系统技术,监测该自然保护区在1985年,1991年,2003年3个时期毛竹林的面积及其变化。结果显示,区内毛竹林面积以平均4.47 hm.a-1的增长速度迅速扩张,并有继续快速蔓延的趋势,严重蚕食了周围原始植被(特别是阔叶林分),在很大程度上破坏了该自然保护区的生物多样性及珍稀濒危物种的保护。认为毛竹林迅速扩张的原因主要是人为干扰极少,毛竹林盖度大(>79%),林下其他植被更新难等。最后提出了促进生物多样性保护的建议。To overcome the sharp conflicts between the expansion of Phyllostachys pubescens stands and the protection of the biodiversity in National Nature Reserve of Mount Tianmn, the areas of Phyllostachys pubescens stands in the nature reserve in 1985, 1991 and 2003 were monitored respectively by the remote sensing and GIS technology. The result showed that the area of the Phyllostachys pubescens stands increased at the average rate of 4.47 hm^2·a^-1, the stands encroaching on the virgin vegetation, especially on the broadleaved forest, which to a great extent disturbed the biodiversity and endangered species in the nature reserve. The rapid expansion of the Phyllostachys pubescens stands was caused by few human interventions, large canopy （ 〉 79% ） of the stands and difficult rejuvenation of other vegetation under the stands. Finally, some suggestions on the protection of the biodiversity were put forward. [ Ch, 2 fig. 1 tab. 8 ref. ]
