| 摘 要： | 该文采用线路统计法,于2010年对四川省西昌泸山国家AAAA级风景名胜区鸟类调查,从调查结果计算出泸山风景区内鸟类频率指数,对鸟类频率指数数量进行等级分析。调查发现在泸山景区鸟类有7目18科59种,其中优势种7种,占11.86%,普通种8种,占13.56%,稀有种44种,占74.58%。从调查结果看,稀有种是泸山景区鸟类组成成分中的主要类群,而优势种较少。泸山的4个植被类型中,灌草丛植被中鸟类较集中;针叶林和阔叶林混交林植被中鸟类出现频率居中;阔叶林植被中鸟类出现的频率较低;农田栽培植被中鸟类分布较为广泛。

| Abstract: | Scientific survey on bird population in Lushan Mountain,the national 4As scenic area in Xichang City,Sichuan Province,has been conducted in the year of 2010 by way of spot sampling,data acquisition and statistical analysis.Based on the survey,the frequency index of bird population has been calculated and its quantitative gradation has been further analyzed.The result shows that there are totally 59 species assigned to 18 families in 7 orders,among which there are 7 dominant species accounting for 11.86%,8 normal species accounting for 13.56% and 44 rare species accounting for 74.58%.Rare species of bird population on Lushan Mountain are in the majority while dominant species in the minority.Among 4 vegetation types on the mountain,birds are rich in shrub-grasser vegetation.Bird occurrence frequency is placed in the middle in the mixed plantations of coniferous and broad leaved forests while low in broad leaved forest.Meanwhile birds are found throughout cultural vegetation in fields. |
