北京喇叭沟门自然保护区森林景观多样性研究

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

Forest landscape diversity of labagoumen Nature Reserve in Beijing

With the help of GIS,the forest landscape characteristics and landscape diversity of Beijing Labagoumen Nature Reserve were investigated in the three regions.The results showed that the forest landscape of Labagoumen Nature Reserve was primarily made up of Quercus mongolica forest and Populus davidiana forest. However, as a result of the destructive activities of human beings, shrub wood and non forest land landscape types began to act their roles in the nature Reserve. Among the three function regions, in the core area,the degree of landscape fragmentation is relatively low. In the buffer zone,the degree of the landscape fragmentation was higher than that in the core area. In the transition area,the landscape fragmentation degree is the highest.
