摘　　要：为了解花面狸的活动节律及其生境选择情况,2017年2月—2019年10月,利用红外相机技术对江西省九岭山国家级自然保护区、齐云山国家级自然保护区和桃红岭梅花鹿国家级自然保护区的花面狸进行了监测,分析了其活动节律,并利用占域模型分析了其生境选择特征.研究结果表明:1)除桃红岭保护区外花面狸的年活动节律均存在显著季节性差异,总体上夏季活动最频繁,其次是春季和秋季,冬季活动最少;但九岭山保护区的花面狸春季活动最频繁.2)花面狸呈现出明显的夜行性,活动高峰期为18:00~6:00,且春季和冬季、夏季和冬季的日活动节律存在显著差异;重叠系数在春季和夏季最高.3)占域模型分析结果显示,影响九岭山和齐云山保护区花面狸占域率的主要因素是植被增强型指数(EVI),占域率随EVI的增大而增大;对桃红岭保护区花面狸占域率影响相对较大的是坡度,且占域率随坡度的增加而增大.In order to understand the activity rhythm of masked palm civetcats and their habitat selection,infrared camera technology is used to monitor masked palm civetin three national nature reserves in Jiangxi Province,namely Jiulingshan National Nature Reserve,Qiyunshan National Nature Reserve and Taohongling Sika Deer National Nature Reserve,from February 2017 to October 2019.The activity rhythm and the characteristic of habitat selection are analyzed using the occupation model.The results show that there are significant seasonal differences in the annual activity rhythm of masked palm civetexcept Taohongling.In general,the activity is most frequent in summer,followed by spring and autumn,and least in winter.However,masked palm civetin the Jiulingshan Reserve are most active in spring.The masked palm civetcat shows obvious nocturnal activity,the peak of activity is 18:00—6:00,and there sre significant differences between spring and winter,summer and winter.The overlap coefficient is highest in spring and summer.The results of domain model analysis show that the vegetation enhancement index(EVI) is the main factor affecting the domain percentage of masked palm civet cats in Jiuling Mountain and Qiyun Mountain,and the domain percentage increases with the increase of EVI.Slope has a relatively great influence on thedomain occupancy rate of civet cats in Taohongling Reserve,and the domain percentage increases with the increase of slope.
