黑龙江省老爷岭南部黄喉貂栖息地适宜性评价与廊道构建OACHSSCDCSCDCSTPCD
Habitat suitability evaluation and corridor construction of yellow-throated marten in southern Laoyeling,Heilongjiang Province,China
黄喉貂(Martes flavigula aterrima)为典型的林栖兽类,对栖息地干扰和破碎化极为敏感,被视为森林生态系统的指示物种.为了科学有效保护该物种,于2020-2021年在黑龙江省老爷岭南部区域布设红外相机642台收集黄喉貂活动位点信息,利用最大熵(MaxEnt)建模方法开展黄喉貂栖息地适宜性研究,探究影响种群生存的关键环境因素,并利用最小成本路径方法构建潜在的种群扩散生态廊道,探讨研究区域黄喉貂种群的栖息地连通性.研究结果表明:(1)MaxEnt模型的受试者工作特征曲线(ROC曲线)评价结果的平均曲线下面积(AUC)值为0.861,能够较好的反映研究区域黄喉貂栖息地适宜性的实际分布情况;(2)本研究利用的13个变量中,距东北虎(Panthera tigris altaica)、东北豹(Panthera pardus orientalis)距离12 km黄喉貂出现概率最高,且贡献率达20.6％,是影响黄喉貂栖息地选择的关键变量,其次坡向(9.9％)、农田(9.5％)、草地(9.0％)、常绿针叶林(8.9％)、道路(7.0％)、河流(6.6％)、居民点(6.1％)和海拔(5.9％)是影响黄喉貂栖息地质量的次要变量;(3)研究区域黄喉貂适宜栖息地面积为793.54 km2,占研究区域总面积的21.4％,主要分布在黑龙江省绥阳林业有限公司的柳桥沟、青山和万宝湾林场.黄喉貂栖息地破碎化严重,因此通过栖息地适宜性分布图获得15块总面积为401.61 km2的核心栖息地,并构建14条生态廊道利于黄喉貂栖息地生态恢复管理.研究综合分析了黑龙江省老爷岭南部黄喉貂栖息地现状及连通性,促进黄喉貂扩散、栖息地的连通性和适宜性.
Yellow-throated marten(Martes flavigula aterrima)is a typical forest dweller that is extremely sensitive to human disturbance and habitat fragmentation,and is regarded an indicator species of forest ecosystems.Aiming to scientifically and effectively conserve the yellow-throated marten,642 infrared cameras were set up in southern Laoyeling,Heilongjiang Province from 2020 to 2021 to collect datasets on the activity locations.The habitat suitability of the yellow-throated marten was analyzed by the MaxEnt method,and the key environmental factors affecting the survival of the yellow-throated marten population.In order to explore the habitat connectivity of the yellow-throated marten's population in the study area,we conduced ecological corridor study using the least-cost path method,and the results of this study showed that:(1)The average AUC(Area under ROC curve)value of Receiver Operating Characteristic(ROC)curve evaluation results of MaxEnt was 0.861,which could better reflect the actual distribution of habitat suitability of the yellow-throated marten in the study area.(2)Among the 13 variables included in this study,the yellow-throated marten had the highest probability of occurrence at about 12 km from Amur tiger(Panthera tigris altaica)and Amur leopard(Panthera pardus orientalis),and the variable contribution rate was 20.6％,which was considered as the key variable affecting the habitat selection of the yellow-throated marten.It was proved that the yellow-throated marten avoided Amur tigers and Amur leopards.In addition,Slope(9.9％),farmland(9.5％),grassland(9.0％),evergreen coniferous forest(8.9％),road(7.0％),river(6.6％),settlement(6.1％)and altitude(5.9％)were the secondary variables affecting the habitat quality of the yellow-throated marten.(3)The suitable habitat area of the yellow-throated marten in the study area was 793.54 km2,accounting for 21.4％of the total area of the study area,which was mainly distributed in the Liuqiaogou,Qingshan and Wanbaowan forest farms of Suiyang Forestry Company of Heilongjiang Province.Although the area of suitable habitat in the study area was large,highly fragmented.Therefore,15 core habitats with a total area of 401.61 km2 were obtained through the habitat suitability distribution map.Finally,14 ecological corridors were constructed to facilitate the ecological restoration and management of the yellow-throated marten habitat in the study area.This study provides a comprehensive analysis of the habitat status and connectivity of the yellow-throated marten,so as to formulate corresponding conservation plans,which can effectively promote the spread,connectivity,and suitability of the habitat in the southern of Laoyeling,Heilongjiang Province.
