四川海子山自然保护区鸟类资源及区系

2003年10~12月和2004年6~9月,采用样线法和绝对数量法,对四川海子山自然保护区鸟类资源进行了调查,记录到鸟类130种,结合文献共16目48科210种。其中以留鸟和夏候鸟为主,占了总数的82.86%。对繁殖鸟类的区系分析表明:古北界种类占繁殖鸟总数的44.8%,东洋界种类占40.8%,广布种占14.4%,古北界种类稍占优势。保护区内有国家Ⅰ、Ⅱ级保护动物30种,我国特有种11种,占我国特有种的15.9%;列入CITES名录的有20种,IUCN名录的有8种,中国物种红色名录14种。垂直区系分析发现:随海拔高度的增加,古北界、东洋界、广布种的比例并不是呈规律性的增加或减少,而是波浪式的变化;绝大多数分布型的比例也呈波浪式的变化。
