Indicators For Rhinopithecus Roxellanae's Habitat Restoration After Earthquake

On the afternoon of May 12,2008,an earthquake measuring 8.0 on the Richer scale hit Wenchuan area of Sichuan,Golden Monkey and its habitat was seriously damaged.The restoration and reconstruction of Gonkey Monkey's habitat receives considerable publicity.In this paper,the Indicator System of Golden Monkey's habitat restoration is discussed.The author sum up 31 analytical methods and 41 influence factors of habitat by reviewing 167 papers on habitat selection of wild animal.Thirty-three samples and 13 factors are set up for quantitative analysis in the habitat of Golden Monkey.Based on the information of field survey and papers,the author analyse its habitat selective mechanism from three aspects,they are food,conceal condition,the hydrological and climatic conditions.In this paper,the key factors affecting the habitat selection of Golden Monkey are divided into three categories:abiological environmental factors,biological environment factors and impacts factors. The Principal Component Analysis shows that there are seven main factors affecting the habitat selection of Golden Monkey.They are average DBH,slope gradient,canopy coverage,elevation,slope position,human disturb,tree height.The most suitable habitat of Golden Monkey is that the elevation is 2400-3000m(54.5%),the slope gradient is 21-30°(48.5%),the slope position is middle slope site(51.5%),the canopy coverage is 50%-75%(84.8%),the average DBH is 21-30cm(57.6%),the tree height is 20-29cm(51.5%).They are sensitive to the human disturb,they select the area far away from kinds of human activities(84.8%).Therefore,the target habitat of restoration is setted.By using the Fuzzy Comprehensive Evaluation Method to evaluate the habitat,the quality of habitat is classified into four grades,they are:most suitable,suitable,marginally suitable,unsuitable. There are three ways of rehabilitation,depending on the practical situation of habitat quality after the earthquake.The author develope the desk application program "The Rhinopithecus roxellanae's habitat restoration system".It makes the process of analysis and evaluation routinely and automatically,and provides the data,graphs and the suggestions for rehabilitation of Golden Monkey.The system not only improve the efficiency and quality for rehabilitation work,but also enhances the scientificity,rationality,availability.This study provides a scientific basis for post-quake restoration and reconstruction of Golden Monkey's habitat.
