摘要
确定野生动物适宜栖息地分布及其影响因子是有效的物种及其栖息地保护和管理的重要基础。本研究于2022年8月至2023年7月间在天马国家级自然保护区内布设240台红外相机对勺鸡(Pucrasia macrolopha)进行监测,确定44个勺鸡分布位点,结合14种环境因子构建MaxEnt模型,对区内勺鸡栖息地适宜性进行评价和分析。结果表明:保护区内勺鸡适宜栖息地面积59.46 km^(2),次适宜栖息地面积145.29 km^(2),主要位于马鬃岭保护站南部、天堂寨保护站北部;勺鸡栖息地适宜性受气候和人为干扰因子影响较大,最冷季平均温度<2.5℃、远离居民点的区域为勺鸡的适宜栖息地。基于野外调查和模型预测结果,表明保护区内勺鸡的适宜栖息地面积较大且质量较高,勺鸡对气候因子和人为干扰因子较为敏感。为遏制保护区内勺鸡栖息地退化,提出了控制人为干扰、开展定期监测以及规划生态廊道的保护建议。
Determining the suitable habitat distribution of wild animals and its influencing factors is a crucial foundation for the effective conservation and management of species and their habitats.This study is based on the deployment of 240 infrared cameras in Tianma National Nature Reserve from August 2022 to July 2023 to monitor Pucrasia macrolopha.It identified 44 distribution sites of Pucrasia macrolopha and employed 14 environmental factors to construct a MaxEnt model for evaluating and analyzing habitat suitability within the reserve.The results show,first,the suitable habitat area of Pucrasia macrolopha in the reserve is 59.46 km~2,and the sub-suitable habitat area is 145.29 km~2,mainly located in the south of Mazongling and the north of Tiantangzhai;Second,the suitability of Pucrasia macrolopha is significantly influenced by climate and anthropogenic disturbance factors,with suitable habitats characterized by an average temperature during the coldest season of temperature below 2.5 ℃ and located away from residential areas.Based on field surveys and model prediction results,it is shown that the suitable habitat area for Pucrasia macrolopha in the reserve is large and of high quality,and Pucrasia macrolopha is more sensitive to climate factor and human interference factor.In order to mitigate the degradation of the habitat in the reserve,protection suggestions were put forward to control human interference,carry out regular monitoring and plan ecological corridors.
