摘要: 于2011-2019年越冬期采用分区直数法对江西鄱阳湖国家级自然保护区9个子湖泊水鸟进行调查,共记录水鸟6目13科74种,越冬期平均数量为(14.85±6.70)万只。区内有白鹤(Grus leucogeranus)、白头鹤(Grus monacha)、黑鹳(Ciconia nigra)和中华秋沙鸭(Mergus squamatus)4种国家Ⅰ级重点保护鸟类,6种国家Ⅱ级重点保护鸟类。2016-2017年越冬期水鸟物种数(56种)和数量(25.33万只)最多;2012-2013年越冬期物种数(27种)和数量(2.38万只)最少。大汊湖年平均水鸟物种数最多,为24.25种,沙湖次之,为23.75种,梅西湖最少,为9.13种。大湖池年平均水鸟数量最多,为46 875.38只,大汊湖次之,为45 749.63只,梅西湖最少,为2 131.13只。多年平均鸟类多样性指数和均匀性指数均以沙湖为最高,分别为2.18±0.30和0.72±0.08,中湖池最低,分别为1.10±0.68和0.45±0.21。根据研究结果对鄱阳湖保护区提出鸟类多样性保护和管理建议。

Abstract: The diversity of wintering waterbirds in the nine sub lakes of Jiangxi Poyang Lake National Nature Reserve was investigated during the wintering periods from 2011 to 2019 by using direct counting method. A total of 74 species of waterbirds belonging to 13 families 6 orders were recorded and the average quantity was (148.5±67.0) thousand individuals in wintering period. There were 4 species (Grus leucogeranus, Grus monacha, Ciconia nigra, Mergus squamatus), that indexed as the first-class of national protected bird and 6 species indexed as second-class of national protected bird in the study area. During the eight wintering periods, the wintering period of 2016-2017 was the highest with 56 waterbirds species and 253.3 thousand individuals. While the wintering period of 2012-2013 was the lowest with 27 species and 23.8 thousand individuals. Among the nine sub lakes, the number of species at Dachahu Lake (24.25 species) was the highest, followed by Shahu Lake (23.75 species), and Meixihu Lake (9.13 species) was the lowest. The number of individuals at Dahuchi Lake (46 875.38 individuals) was the highest, followed by Dachahu Lake (45 749.63 individuals), and the lowest was Meixihu Lake (2 131.13 individuals). Both of the Shannon-Wiener diversity (H') and the Pielou evenness index (J') of waterbirds at Shahu Lake (H'=2.18±0.30, J'=0.72±0.08) were the highest, and both of them at Zhonghuchi Lake (H'=1.10±0.68, J'=0.45±0.21) were the lowest. Based on the results and current situation, relevant proposals for conservation and management of bird diversity in Jiangxi Poyang Lake National Nature Reserve were offered.
