摘要: 近年来被动声学监测技术被广泛应用于陆生哺乳动物的监测,它能以较低的价格和非侵入的方式在特定区域进行野生动物无人值守监测,面临的主要问题是需要人工收回数据和后期数据分析整理较为困难。本研究设计了一套被动声学监测系统用于西黑冠长臂猿监测,监测系统在野外由太阳能供电,使用自研的指向性拾音器阵列采集鸣声数据,并通过无线网桥实时传输数据至管护局办公楼的服务器进行存储,通过后台的鸣声数据管理系统辅助研究人员识别鸣声和辨认鸣声来源方向,简化数据采集和处理流程。该系统在哀牢山国家级自然保护区枇杷箐科研监听点对两个西黑冠长臂猿群体进行了351天的连续监测,特点为:系统运行长期稳定,数据通过无线方式传输便捷高效且不受季节天气影响。指向性拾音器阵列能有效分辨长臂猿鸣声来源方向,弥补了传统监测设备难以分辨鸣声方向的缺陷。该系统与现有人工监测方法相比在数据采集的持续性、连续性、完整度以及鸣声数据处理智能化和监测成本方面均具有一定优势,符合西黑冠长臂猿持续长期监测需求,未来可作为西黑冠长臂猿自动化监测的解决方案进行推广应用。

Abstract: Passive acoustic monitoring technology has recently been widely used in the monitoring of terrestrial mammals. Such technology enables the unattended monitoring of wildlife in specific areas at low cost and in a non-invasive manner. The main problem, however, is the need to retrieve data manually. Moreover, the subsequent data analysis and sorting are more complicated. In this study, a passive acoustic monitoring system was designed for monitoring the western black crested gibbon (Nomascus concolor). The monitoring system is powered by solar energy in the field. Sound data are collected by the directional pick-up array. The data are transmitted through a wireless network to a server in the management office building. Researchers are assisted in identifying the sound and the direction of the sound by the sound-data management system, which simplifies the data collection and processing. The system has continuously monitored two groups of western black crested gibbons for 351 days at the scientific monitoring site of Pipaqing in the Ailao Mountain Nature Reserve. Results showed that the system had a long continuous run-time and was not affected by the weather conditions; data transmission was convenient and efficient; the directions of sound source could be well determined by the directional pick-up array, overcoming the shortcomings of traditional monitoring equipment; the system had advantages over manual monitoring methods in terms of data continuity and integrity, intelligence in data processing, and monitoring costs. This system meets the continuous long-term monitoring needs of western black crested gibbons, and may be improved and applied in the future as an automated solution for the monitoring of this primate species.
