基于水上智能监测系统的南京长江江豚数量和集群调查与分析

Population size and aggregation investigation and analysis of the Yangtze finless porpoise in Nanjing,based on intelligent monitoring system

该文基于可见光和红外相结合的生物感知手段,准确获取了2020—2021年水上智能监测系统的时点数据,分析了南京长江江豚监测数量的年监测总量、月动态变化以及集群数量,讨论了区域内江豚数量变化走势及影响因素,并初步探讨了提升监测精度范围的手段,为长江江豚种群保护工作提供借鉴。

In this article,with the time point data of the intelligent monitoring system on the water accurately presented from 2020 to 2021,based on the biological sensing technique combining visible light and infrared,the total annual monitoring amount of Yangtze finless porpoises in Nanjing,the monthly dynamic change of the monitoring number,and the number of clusters were analyzed.And the change trend of the number of Yangtze finless porpoises in the region,and the influencing factors were discussed.Furthermore,the means to improve the monitoring accuracy range were preliminarily dealt with,which could provide reference for the protection of Yangtze finless porpoises population.
