摘　　要：利用云南省永仁县1∶50000地形图和1999年Landsat-7 ETM遥感影像对区域森林景观空间格局特征进行了初步研究。结果表明:①森林景观是区域景观的基质,对区域及流域生态安全起到重要作用;②当前区域森林景观空间格局特征是在自然因素与人为因素的综合作用下形成的,地形因子是形成森林景观自然分布特征的首要因素,而人类活动干扰则是促使当前森林景观分布特征形成的重要因素;③人类活动干扰导致的区域退化森林生态系统类型分布较广,制定适宜的管理方法与经营措施,加强对现存稳定植被类型的保护和退化森林生态系统的恢复是当务之急。The spatial distribution features of all the forest landscape components in the representative area of Jinshajiang Watershed of Yunnan are analyzed by the topographic contour map（scale= 1 ： 50 000） and TM imagery in 1999. The results showed that ： （ 1）The matrix landscape in this area is forest landscape. It plays an important role in ecological security of Yangtze River. （2） The spatial distribution features of forest landscape are affected by topographic characteristics and anthropogenic disturbance. Topographic characteristics are critical for the natural distribution features of forest landscape. However, anthropogenic disturbance is an important factor to influence the current spatial distribution features. （3） It is urgently to develop appropriate management and operation measures, protect the stability of the existing vegetation types, restore degraded the forest ecosystem restoration due to its widely distribution.
