四川省鸡形目鸟类及分布

研究使用了从1997~2005年四川省58个生物资源综合科学考察的鸟类野外调查记录、国内外从1908年到2005年有关四川省鸡形目鸟类野外物种调查公开发表的60篇文献,以及四川大学、西华师范大学、四川农业大学标本馆共386号鸡形目标本,共1103条记录,对四川省鸡形目的资源及分布进行了研究。结果如下:①四川省鸡形目鸟类计2科18属25种,占全国鸡形目(63种)的39.68%,其中,国家I级保护鸡形目5种,国家II级保护鸡形目11种,分别占全国保护鸡形目总数(I级21种、II级21种)的23.81%、52.38%;特有种7种,占全国鸡形目特有种(14种)的50%,分布型以喜马拉雅-横断山区型居多,以东洋界成分占绝对优势。②物种丰富度最高的地区为平武县、松潘县、九寨沟县、绵竹县、冕宁县、康定县、青川县和宝兴县,保护物种丰富度最高的地区为平武县、九寨沟县、宝兴县、松潘县、青川县、冕宁县;③四川省159个县(市)中有鸡形目调查记录的有73个,没有记录的县86个,这86个空白区域有待进一步调查。

Distribution and Conservation of Galliformes in Sichuan

Sichuan is one of the most important habitats of Galliformes in China.A study was conducted to research the distribution and conservation of Galliformes in Sichuan.The data are based on the results of 58 provincial field surveys in recent 10 years,and reports and literatures collected from 1929 to 2005 by both Chinese and foreign researchers and the samples of three museums in Sichuan.The results show that: 1) 25 species of Galliformes are recorded,among them 16 species are national protected birds,and 7 species are endemic to China.2) According to the analysis of the richness of Galliformes by GIS,Pingwu,Songpan,Nanping,Mianzhu,Yele,Kangding,Qingchuan and Baoxing are the richest counties in Galliformes in Sichuan.Pingwu,Songpan,Nanping,Yele,Kangding,Qingchuan and Baoxing are the richest counties in protected Galliformes in Sichuan.3) There are 86 counties(of 159 in total) which are short of records of Galliformes.These counties need more field works on Galliformes distributions.
