第51卷第1期2023年3月贵州林业科技GuizhouForestryScienceandTechnologyVol.51,No.1Mar.,2023基于红外相机技术的雷公山保护区白颈长尾雉生境利用分析吴必锋,李萍,李登江,郑德谋,余德会,杨宗才,田洪金(贵州省雷公山国家级自然保护区管理局,贵州雷山557199)摘要:生境是动物生存和繁衍的场所,生境的质量及其可利用程度是决定动物种群存亡的关键。本文应用ArcGIS对DEM的海拔和坡向数据进行自然间断点分级(Jenks)和重分类(Reclass),各分为4个梯度后与4个植被类型进行叠加分析(Intersect),系统性抽样64个固定样地,利用红外相机开展白颈长尾雉Syrmaticusellioti监测和生境利用调查。结果显示:雷公山保护区白颈长尾雉对低海拔和中低海拔有选择性,对坡向无选择性,对阔叶林和针阔混交林有选择性。应加大天然林保护力度,丰富植物群落的垂直结构和多样性,为白颈长尾雉等鸟类提供更多的栖息场所及食物来源。关键词:白颈长尾雉;雷公山保护区;红外相机;生境利用中图分类号:S759.9文献标识码:AHabitatUtilizationofSyrmaticuselliotiinLeigongshanNatureReserveUsingInfraredImagingWUBi-feng,LIPing,LIDeng-jiang,ZHENGDe-mou,YUDe-hui,YANGZong-cai,TIANHong-jin(GuizhouLeigongshanNatureReserveAdministrationBureau,Leishan,Guizhou557199)Abstract:Habitatistheplacewhereanimalsliveandreproduce.Thequalityandavailabilityofhabitatareessentialtothesurvivalofanimalpopulation.Inthispaper,asystematicanalysiswasperformedonthehab-itatutilizationofSyrmaticuselliotiintheLeigongshanNatureReserveusinginfraredcameratechnology.FourgradientswerealsoclassifiedintheelevationandslopedirectiondataofDEMusingArcGIS.Fourveg-etationtypeswerethenintersected.Afterthat,64fixedsampledplotsweresystematicallysegmentedtomonitorthehabitatutilizationusinginfraredcamera.TheresultsshowedthatSyrmaticuselliotiinLeigong-shanNatureReservewaspreferredtothelowaltitudeandmiddle-lowaltitude,withouttheselectivitytotheslopedirection.Furthermore,therewastheselectivitytothebroad-leavedforest,orconiferousandbroad-leavedmixedforest.Somesuggestionswereproposedtostrengthentheprotectionfortheverticalstructureanddiversityofplantcommunities.Itisahighdemandtoprovidemorehabitatandfoodsourcesforthebirds,suchasSyrmaticusellioti...
