| 为探究雷公山国家级自然保护区毛冠鹿的活动规律与栖息地选择特征,于2018年12月至2021年4月,采用分层随机抽样方法,在保护区内不同林型和海拔梯度布设红外相机进行监测。共设置有效相机位点133个,累计工作27 725 d,获得毛冠鹿有效独立照片525张。结果表明,保护区内毛冠鹿的RAI指数为7.26;林型、季节与海拔梯度对毛冠鹿活动均具有一定影响,其中季节和海拔的影响达到极显著水平(P<0.01);不同林型、季节和海拔梯度与毛冠鹿拍摄率间均呈负相关(Pearson系数<0),其中季节、海拔与拍摄率间呈极显著负相关(P<0.01),而林型的相关性不显著。在活动节律方面,毛冠鹿在夏季活动强度最高,春季与秋季次之,冬季显著降低;在生境选择方面,毛冠鹿RAI指数随海拔升高呈递增趋势,高海拔区域利用强度高于低海拔,不同林型间以针叶阔叶混交林和落叶阔叶林内的活动频次相对较高。以期为保护区建立毛冠鹿监测体系及制定相应保护策略提供科学依据。 |

| To investigate the activity patterns and habitat selection characteristics of Elaphodus cephalophus in Leigongshan National Nature Reserve, this study conducted infrared camera monitoring using a stratified random sampling method across different forest types and elevation gradients within the reserve from December 2018 to April 2021. A total of 133 effective camera sites were deployed, accumulating 27 725 camera-days of monitoring and yielding 525 valid independent records of E.cephalophus. Data were analyzed using the relative abundance index (RAI), chi-square tests, and Pearson correlation analysis. The results showed that the RAI of E.cephalophus in the reserve was 7. 26. Forest type, season, and elevation gradient all had statistically effects on the activity of E.cephalophus, with season and elevation showing extremely significant effects (P<0. 01). Correlation analysis indicated that forest type, season, and elevation gradient were all negatively correlated with the capture rate of E.cephalophus (Pearson coefficient<0). Specifically, season and elevation exhibited an extremely significant negative correlation with the capture rate (P<0.01), while the correlation with forest type was not significant. In terms of activity rhythm, E.cephalophus exhibited the highest activity intensity in summer, followed by spring and autumn, with a marked decline in winter. Regarding habitat selection, the RAI showed an increasing trend with elevation, with higher utilization intensity in high-altitude areas compared to low-altitude ones. Among different forest types, the activity frequency was relatively higher in coniferous broad-leaved mixed forests and deciduous broad-leaved forests. The findings of this study provide a scientific basis for establishing a monitoring system and formulating conservation strategies for E.cephalophus in the reserve. |
