摘要: 掌握鹅喉羚活动规律和适宜生境分布,有助于理解鹅喉羚适应环境变化的生存策略,可为制定物种保护对策提供科学依据。本研究利用红外相机技术和物种分布模型开展了中卫沙坡头国家级自然保护区及周边鹅喉羚活动规律和适宜生境分布研究,评估了保护空缺。结果表明: 2022年10月—2024年5月,安装在沙坡头保护区的136台红外相机累计工作67456个相机日,共记录到5520张鹅喉羚独立照片。其中,春季1154张,夏季712张,秋季1343张,冬季2311张。沙坡头保护区鹅喉羚种群日活动呈现昼行性规律,活动高峰呈明显的晨昏双峰模式。在BIOMOD2平台的6种模型中,最大熵模型模拟效果最好,表面分布区分室模型评分最低;真实技巧统计值(TSS)和受试者工作特征曲线下面积(AUC)分别为0.996和0.940,表明模型预测结果优秀。BIOMOD2模型结果表明,沙坡头地区鹅喉羚适宜生境总面积为47493 hm2,其中,高适宜生境面积为35751 hm2,中适宜生境面积为11742 hm2。当前沙坡头保护区保护了15.8%的鹅喉羚适宜生境,将长流水区域整合优化纳入保护区范围后,可提高保护比例至43.3%。本研究掌握了沙坡头地区鹅喉羚活动规律和适宜生境分布,丰富了对其行为生态学的认知,可为沙坡头保护区制定鹅喉羚保护对策提供科学依据。

Abstract: Understanding the activity pattern and distribution of suitable habitats of Gazella subgutturosa can help reveal its survival strategy under changing environments, and provide a scientific basis for formulating the conservation countermeasures. In this study, we used infrared camera technology and species distribution model to analyze the activity pattern and distribution of suitable habitats of G. subgutturosa in Zhongwei Shapotou National Nature Reserve and its surroundings, aiming to assess the conservation gaps. The results showed that, from October 2022 to May 2024, the 136 infrared cameras installed in the Shapotou Reserve worked for a total of 67456 camera days and recorded a total of 5520 independent photographs of G. subgutturosa. Among them, 1154 photographs were taken in spring, 712 in summer, 1343 in fall, and 2311 in winter. The daily activity of G. subgutturosa in the Shapotou Reserve showed a diurnal pattern, with activity peaks in morning and evening. Out of the six models from BIOMOD2 platform, the maxent simulation performed the best and the surface distribution differentiation chamber model performed the worst. The model provided satisfactory results, with the TSS value of 0.996, and the AUC value of 0.940. The model results showed that the total area of suitable habitat for G. subgutturosa was 47493 hm2 in the Shapotou, of which 35751 hm2 was highly suitable habitat and 11742 hm2 was moderately suitable habitat. Shapotou Nature Reserve had protected 15.8% of the suitable habitat for G. subgutturosa, and the value would increase to 43.3% after Changliushui area being included into the reserve. This study grasped the activity pattern and distribution of suitable habitats of G. subgutturosa in Shapotou area, enriched the knowledge of its behavioral ecology, which would provide scientific basis for the formulation of G. subgutturosa conservation strategies and the adjustment of the protected area boundary in Shapotou Nature Reserve.
