铅山县鸟类繁殖期多样性动态观测研究

Bird diversity dynamic observation research during breeding period in Yanshan County

鸟类多样性研究一直是生物多样性保护的重点工作。采用样线法调查,于2016-2019年在铅山县选择3个典型观测亚区,共设12条样线,样线总长度28.0 km。每年繁殖期前后各观测一次,共记录到繁殖鸟15目43科163种7549只次,占江西省鸟类物种总数的33.89%。种数最多的目为雀形目,种数最多的科为画眉科,只数最多的为烟腹毛脚燕Delichon dasypus。记录到国家重点保护鸟类6种,样区新记录种9种。观测到种数最多的是2018年,只数最多的是2017年。3个亚区种数为保护区亚区>河口镇亚区>武夷山镇亚区,种数和只数繁殖后>繁殖前。通过单因素方差分析结果表明:2016-2019年样区鸟类种数、只数以及Shannon-Wiener多样性指数(H)、Pielou均匀度指数(E)均呈差异不显著,繁殖前后方差结果亦如此。而各观测亚区间种数、只数和指数E呈显著性差异,仅指数H差异不显著。

Bird diversity research has always been a priority for biodiversity conservation.Three typical observation sub-regions were chosen for sample line method in Yanshan County from 2016 to 2019,twice a year before and after breeding period.12 sample lines were set with a total length of 28.0 km.A total of 7549 breeding birds were recorded including of 15 orders 43 families 163 species,accounting for 33.89%of the total bird species in jiangxi province.The most species order was Passeriformes,and the most species family was Timaliidae.The largest individuals were Delichon dasypus.6 species national key protection birds and 9 new records were surveyed.The most species observed in 2018 and the largest individuals observed in 2017.The species of the three sub-areas were the reserve>Hekou town>Wuyishan town,and after breeding period>before breeding period with the species and individuals.The results of one-way analysis of variance showed that there were no significant difference in the species or individuals and Shannon-Wiener diversity index H or evenness index E during 2016-2019,and so did the variance before and after breeding period.However,the three sub-regions showed significant difference in the species or individuals and index E,but the index H.
