吉林省左家自然保护区鸟类组成及其多样性研究

对吉林省左家自然保护区40年来鸟类组成的动态变化及变化原因进行了分析.结果表明,至2006年全区共见鸟类190种,隶属于17日、49科、103属,其中繁殖鸟(夏候鸟和留鸟)113种,占全区鸟类种数的59.5%.记录到国家二级保护种类30种;吉林省二级保护种类12种、三级保护种类21种.按照鸟类栖息的生境及植被特点,将自然保护区分为4个不同类型的群落,并对每个群落的多样性、均匀性及相似性进行了比较.其中次生林群落多样性指数最高(2.980),均匀性指数也最高(0.611);次生群落与灌丛群落的相似性指数相对高一些,为0.339.

The study of composition and diversity of birds in Zuojia nature preserved area,Jilin Province

This paper compared birds composition and dynamic changing before and after 40 years in Zuojia nature conservation area in Jilin Province,then analyzed the reason for dynamic changing.The results showed that,there were 190 species of birds in 2006,which belonged to 17 orders,49 families,103 geneses.Among 190 species of birds,there were 113 species of breeding birds(summer migratory birds and resident birds),which was 59.5 percent of the total number.There were 30 species of birds listed as the national secondary grade wildlife of China for protection.There were 12 species and 21 species listed as the national secondary and third grade wildlife of Jilin Province for protection,respectively.According to the habitats of birds and vegetation characteristics,we divided the nature conservation area into four different types of communities,and compared each community's grade diversity of birds and the index of homogeneity and similarity.The diversity and index of homogeneity were the highest in the secondary forest community(2.980) and(0.611),respectively.The index of similarity was much higher in secondary forest and brush community(0.339).
