【Abstract】 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.更多还原
