广东连南板洞省级自然保护区鸟类多样性初步调查

鸟类多样性研究是自然保护区的重要工作之一。2021年1—12月，采用样线法和样点法，调查了广东连南板洞省级自然保护区鸟类多样，共记录到鸟类15目54科211种。其中国家Ⅰ级和Ⅱ级重点保护鸟类分别为2种和34种；区系以东洋界为主，有129种（61.72%），古北界44种（21.05%）。居留型以留鸟为主，有136种（65.07%），冬候鸟40种（19.14%）。优势种为栗颈凤鹛Staphida torqueola和淡眉雀鹛Alcippe hueti；常见种和少见种分别 为27种和59种。Shannon-wiener多样性指数、Marglef丰富度指数、Pielou均匀度指数和Simpson指数计算结果均为板洞保护站最高。该保护区是每年大批鹭鸟等候鸟迁徙的必经路线，建议加大监测力度，掌握候鸟变化动态等。

A Preliminary Investigation on the Bird Diversity of Bandong Provincial Nature Reserve

Bird diversity research is an important work in nature reserves. From January 2021 to December 2021, the bird diversity in Bandong Provincial Nature Reserve, Liannan County, Guangdong Province, was investigated by using the method of transect and sampling point. The results showed that a total of 211 species were recorded, belonging to 15 orders, 54 family. Among these, 2 species were listed in the first category and 34 species in the second category of the Lists of Wildlife under Special State Protection in China. The fauna was dominated by the oriental bird, with 129 species, and 44 species were palaearctic bird. The resident bird had the advantage, with 136 species and 40 species were winter bird. The dominant species were Staphida torqueola and Alcippe hueti, with 27 common and 59 rare species, respectively. The calculation results of Shannon Wiener diversity index, Marglef richness index, Pielou evenness index and Simpson index in reserve are the highest in Bandong Protection Station. The reserve is a necessary route for the migration of a large number of herons and other migratory birds every year, and it is suggested to strengthen monitoring and timely grasp the change dynamics of migratory birds
