摘要
Landscape connectivity is a parameter of landscape function, which measures the processes by which the sub populations of organisms are interconnected into a functional demographic unit. It is a landscape phenomenon which describes the relationships between landscape subunits. Landscape connectivity can be measured by measuring the degree to which the landscape pattern facilitates or impedes movement of animals among resource patches, particularly for conserved animal species. In this paper, the landscape connectivity for Giant Panda in Wolong Nature Reserve was evaluated by using landscape ecological model on the base of choosing three natural affecting factors on Giant Panda and using geographic information system. The results demonstrate that only about 90 36 km 2 (c.a.4 47%) of total area 2023 31 km 2 is most suitable for Giant Panda survival, the suitable area is about 226 42 km 2 (11 19%), the moderately suitable area is 286 09 km 2 (14 13%), as much as 1236 51 km 2 is completely unsuitable for Giant Panda living. The result will be helpful for making a decision on improving eco environment and protecting Giant Panda in Wolong Nature Reserve.
