Of Gaoligongshan Takin Habitat Restoration And Optimization Studies

Takin (Budorcas taxicolor) is a sort of large herbivorous animals, which involves four existent subspecies: B .taxicolor .taxicolor, B. taxicolor bedfordi, B. taxicolor tibetana and B. taxicolor white. It's the special large animal in Asian, and is called the three rarest animals with panda(Ailorupoda melanoleuca)and snub-nosed monkey (Rhinopithecus spp)inhabited in alpine mountain forest in China. Because of the only inhabited area in the East Asian and the south Asian, Takin is the first class protected animal and has an important to the scientific study. Gaoligong Mountains lies in the broad areas between China and Burma where belongs to the south part of Henduan Mountains. The latitude is 24° 40' - 28° 30' N and 97° 30' - 99° 00' E. The regions included the wide areas between the Nujiang River watershed and Nmai Hka River. Gaoligong Mountains are one of the distribution centers of species diversity, which have the global meaning in China and the best important distribution center of B .taxicolor .taxicolor.With the expansion of human activities, the change of habitat pattern and the fragmentation have became the supreme threaten to the living development of rare wide animals. In the field study, due to the complexity of wide animals' migration and regional physical conditions, the traditional methods of zoological field work are hard to deal with the problems of habitat fragmentation and restoration. The appearance and application of 3S technology provide the support to the general study of wide animal habitat. In this paper, the author takes the Takin of Gaoligong Mountains as study object, attempts to use the theory and methods of spatial statistics to analyze the spatial autocorrelation of Takin habitat factors in study sampling area, and the landscape heterogeneity in study sampling area from 1974 to 2002, nearly 30 years. And based on the confirmation of influence factors, the author sets up the assessment system of the habitat suitability of Gaoligong Mountains Takin, and brings forward the blue print of habitat restoration and plan.The main contents of this study are as follows:1. The spatial autocorrelation analysis of Takin habitat factorsWith the case study of Gaoligong Mountains Natural Reserve, the paper provided a quantitative method to analyze the influencing factors to the Takin (Budorcas taxicolor) habitat, using spatial statistics based on GIS. The paper analyzed the spatial autocorrelation of identifying potential variables, confirmed the main influencing factors including land cover, elevation, slope, road and resident, and provided scientific recommendations for the protection and management of Gaoligong Mountains Takin.2. The analysis of habitat heterogeneity and spatial patternBased on the multi-temporal landscape remote sensing study data in mid-south Gaoligong Mountains areas, with the using of a spatial variance, NDVI, mesh sampling method and...
