EVALUATION ON GIANT PANDA HABITAT FRA GMENTATION IN WOLONG NATURE RESERVE
卧龙自然保护区大熊猫生境破碎化研究

Habitat fragmentation comprises following two parts:morphological fragmentation(landscape structure)and fragmentation on ecological function.Landscape connectivity as a parameter measuring ecological processes by which the subpopulations of a landscape are interconnected into a demographic functional unit,was applied in this study for evaluating the habitat suitability and fragmentation for Giant Panda in Wolong Nature Reserve from natural landscape factors.It was carried out by using landscape ecological model and Geographic Information System.It is found that only 90 36km 2(4 47%) of the total area is most suitable for Giant Panda living,the suitable area is 226 42km 2(11 19%),the moderately suitable area is 286 09km 2(14 13%),and 177 91km 2(8 8%)is marginally suitable area.It is found that more than 60%,about 1236 51km 2 is completely unsuitable for Giant Panda living.The results also show that the most suitable area and the suitable area for Giant Panda living are in extremely fragmented situation from spatial distribution,which is unfavorable for Giant Panda's conservation.This study provides a foundation for making decision on improving habitat and protecting Giant Panda in Wolong Nature Reserve.
