Study On Landscape Ecological Pattern And Restoration Of Forest Musk Deer's Habitat In Fengxian County, Shaanxi Province

Forest musk deer (Moschus berezovskii), the first-class protected wild animal in China and endangered wild species in the list of the Red book of IUCN and China Endangered Animals, distributed in the region through the Hengduan Mountain to the Southeastern Qingzang Plateau. It is the most popular species among the musk deer lived in China.Applied "3S" technology, the landscape ecological pattern and its dynamics of forest musk deer's habitats were analyzed in Fengxian County, Shaanxi Province. The history and current distribution, the population density of the musk deer also were studied by the field survey and questionnaire from November 2003 to August 2005. Otherwise the relationship between of the density of forest musk deer and their habitat landscape ecological pattern was studiedThe following results have been concluded based on the analysis, and the recommendation for increasing the population of musk deer through the habitat restoration also provided:1. The six forest musk deer's habitats were the natural ecological landscape based on conifer and broadleaf forest. The conifer and broadleaf forest was the dominant patch class and held 60% in all the landscape area. Wuliangshan nature reserve had the highest largest patch index (LPI, 34.88 hm²), the highest mean patch density(PD, 2.6512 个? km^-2), the highest edge density(ED, 30.88 m ? hm^-2) and the smallest mean patch area(21.61 hm²). From the view of landscape area, patch density and edge character, Wuliangshan nature reserve was the largest fragmentation in all of the six forest musk deer habitats in Fengxian County.There were low diversity and heterogeneity, and high dominant patch class in all the six forest musk deer habitats. The highest Shannon's diversity index (SHDI) was 1.1044 only, and the highest Shannon's evenness index (SHEI) was 0.6862. There were high cohesion and aggregation of patches. The patch cohesion index (COHESION) kept high (97.172-98.188) in all the six forest musk deer habitats. Wuliangshan nature reserve had the most complex and smallest self-similarity in geometrical shape. Its perimeter-area fractal dimension (PAFRAC, 1.615) was the largest in all the six habitats. On the contrary, Pingmu habitat had the simplest and highest self-similarity in geometrical shape and PAFRAC only in 1.5156.
