摘要
21世纪以来,中国野生鸟类物种数持续增长。特别是1947年《中国鸟类名录》出版之后,到2018年,又产生较多新记录,但各省份鸟类新纪录的时空分布、影响因素尚未研究。基于各省份鸟类新纪录的鸟类种类、分布状况,结合可能影响其分布的环境因子,探索新纪录鸟种出现的原因。研究发现,各省份鸟类新纪录主要分布于我国北部地区(新疆、内蒙古、黑龙江)、东部沿海以及南部沿海地区。其中,内蒙古鸟类新纪录最多,广东次之,而新纪录较少的为上海(3种)和天津(2种)。结合2000—2018年各省份鸟类总数、生境类型和新纪录鸟种数据进行回归分析,结果发现新纪录鸟种数分别与耕地、林地、草地和水域面积呈显著正相关。
Since the 21st century,the number of wild bird species in China has been increasing constantly.From 1947 when the publication of“Checklist of Chinese Birds”to 2018,new bird records have been growing rapidly.However,the spatial and temporal distribution of new recorded birds is unclear.The classification and distribution of these records are summarized and the reasons for the appearance of these new recorded bird species are also explored.The results show that the new recorded bird species are mainly distributed in north China(including Xinjiang,Inner Mongolia and Heilongjiang),east coast and south coast.Inner Mongolia Autonomous Region recorded the highest number of new bird species,followed by Guangdong Province,while Shanghai and Tianjin recorded the least.Combined with the data of the total number of birds,habitat types in each province and the new recorded bird species from 2000 to 2018,we found that the newly recorded bird species had a significant positive correlation with cultivated land,woodland,grassland and water area.
