基于GIS的卧龙自然保护区大熊猫生境选择与利用
GIS-based Research on Giant Panda Habitat Selection and Use in Wolong Nature Reserve
摘要
Abstract
Used ArcGIS 10.2,we quantitatively analyzed the characteristics of habitat selection (The ratio between the area of wildlife used habitat and home range area) and use (The ratio between the area of a habitat factor in home range of wild life and the type of entire protected area)of giant panda (Ailuropoda melanoleuca) on terrain (e.g.,elevation,slope and aspect) and biological factors (e.g.,vegetation,bamboo) in Wolong Nature Reserve,Sichuan China.The results showed that giant panda prefer to the elevation range of 2 000～3 500 m,accounting for 89.64％ of this elevation in entire protected area,while elevation selection mainly were found at the range of 1 500～3 000 m,accounting for 55.93％ of the total space use area of giant panda.Giant pandas' habitat use on slope were relative unifier,mainly ranging from 20°～50°,accounting for 85.56％ of the distribution.The aspect for panda use ranged from 270°～315°,accounting for 31.88％ of the whole protected area,but on home scale,they more preferred to choose the aspect ranging from 135°～315°.The majority of pandas' habitat utilization were found in the coniferous forest and mixed evergreen and deciduous broad-leaved forest,accounting for 51.04％ and 70.20％ of the total area distribution respectively.The main vegetation types in habitat selection of giant panda were coniferous forest and mixed needle,accounting for 90.23％ of the space use area;51.63％ of pandas' utilization distribution were in arrow bamboo forest,while,pandas more like to choose Fargesia robusta and Bashaniafangiana which accounted for 95.20％ within home range.Our results reveal differentiation among different terrain intervals and biological factors in panda habitat utilization and selection patterns.This research further enriches methods in analyzing panda habitat selection and use characteristics.关键词
