摘要：于2015—2019年5月和6月采用样线法结合样点法对内蒙古图牧吉国家级自然保护区繁殖期鸟类进行实地调查观测,并分析鸟类群落多样性和均匀性年际和月份变化,以确定鸟类种群动态变化规律。结果表明,保护区繁殖期鸟类共观测到99种,隶属15目33科,以雁形目(Anseriformes)和鸻形目(Charadriiformes)鸟类为数量优势种,大鸨种群动态呈显著时空变化。保护区鸟类物种种数和种群数量呈显著空间差异,鸟类群落多样性呈显著年际差异和空间差异,湿地鸟类多样性高于草地,以农田为主的栖息地最低;保护区鸟类群落多样性平均值为2.39±0.39。鸟类均匀度指数平均值为0.33±0.05,且存在显著空间差异。关注繁殖期鸟类可确定重点保护时段和保护区域,提高自然保护区保护力度,确保繁殖期鸟类免受人为干扰。同时,应加强保护区生物多样性保护与监测,为自然保护区管理成效评估和保护政策优化提供科学支撑。
Birds are important indicative organisms of habitat changes.Through continuous monitoring and analysis of birds in a given area,we can objectively understand the trend of bird species diversity.Inner Mongolia Tumuji National Nature Reserve is well known for conserving the iconic endangered species,such as great bustard(Otis tarda dybowskii)and red-crowned crane(Grus japonensis),as well as the important bird breeding area,stopover site and wintering ground in China.Due to long-term farmland reclamation and overgrazing,the grassland and wetland in this reserve had been degraded,and bird habitats had been suffered from fragmentation,which had influences on the bird population dynamics.However,the inter-annual and monthly variability of bird population dynamics is not yet clear.The aim of this study is to analyze the temporal and spatial changes of bird diversity in Tumuji Nature Reserve,and determine the dynamics of bird populations.By combining line transect and point count surveys,the birds were field monitored and surveyed during the breeding season for five consecutive years on May and June from 2015.Based on the monitoring data,the population dynamics,bird diversity and bird evenness index were analyzed in Tumuji nature reserve for the past 5 years(2015-2019).A total of 99 species of birds were detected belonging to 15 orders and 33 families,of which Anseriformes and Charadriiformes are the dominant species,and the population size of great bustard showed a spatial and temporal change.There were significant spatial differences in the number of bird species and population size.The average bird community diversity was 2.39±0.39 across all surveying sites,with wetland being higher than that in grassland,and farmland-dominated habitat diversity the lowest.The average evenness index was 0.33±0.05,and birds distribution varied among geographical sites.Conservation practice should be directed to the breeding season,and surveying intensity should focus on determining the key protection area,and ensure that the bird breeding is free from human interference.Meanwhile,it will facilitate the protection and monitoring of biodiversity,and provide scientific support for evaluating the effectiveness of protected area management and optimizing protection policies.
