该文以北京喇叭沟门自然保护区为研究对象 ,借助地理信息系统 (GIS)手段 ,对其森林景观特征及多样性进行研究 .结果表明 ,喇叭沟门自然保护区森林景观以蒙古栎 (Quercusmongolica)林、山杨 (Populusdavidiana)林为主体 ,但因人为破坏等原因 ,灌木林和非林地景观类型亦占较重要的位置 .保护区的 3个功能区中 ,核心区景观破碎化程度低 ,缓冲区景观破碎化程度相对较高 ,试验区内景观破碎化程度最高 This paper takes Labaogoumen Nature Reserve in Beijing as the research object, and studies the characteristics and diversity of the forest landscape by means of geographic information system (GIS) .The results show that the forest landscape in Labaigoumen Nature Reserve is dominated by Quercus mongolica ) And Populus davidiana forest, but the landscape types of shrub forest and non-forest land also occupy a more important position due to man-made damage, etc. Of the three functional areas in the reserve, the degree of fragmentation in the core area is low, The degree of fragmentation of the buffer landscape is relatively high, and the degree of landscape fragmentation in the experimental area is the highest
