中文摘要：

2016年8月,对江西省贵溪市境内的阳际峰国家自然保护区鸟类群落结构进行了调查,共记录到鸟类56种611只,隶属于10目、26科。其中雀形目鸟类在个体数量和种类上都占据了优势地位,树麻雀是其中的优势种。在居留型组成上,留鸟无论在个体数量还是种类数量上都占据优势,分别为83.6%和80.3%。阳际峰国家自然保护区鸟类群落多样性指数为3.36,均匀度指数为0.83。在调查的6中鸟类生境中,阔叶林群落鸟类多样性最高,为3.08,而混交林的均匀性指数最高,达到0.92。分析结果表明,各群落之间相似性较低。其中阔叶林生境与村落生境之间的相似性指数最高,达到0.43;混交林生境与灌丛生境的相似性指数最低,为0.09。总之,栖息地的相似性则决定了鸟类群落结构组成的相似程度,包括生产力的不同、种间竞争、不同程度的人为干扰在内的诸多因素决定了鸟类分布的不同。在这些因素当中,栖息地的生产力高低是决定不同生境鸟类分布数量的最大影响因素。在保护区内的6个不同生境中,阔叶林生境和村落生境拥有最大的生产力,两者也拥有最多的鸟类数量和种类。

英文摘要：

The avian community was conducted in August 2016 at Yangjifeng Nature Reserve of Jiangxi Province. The results showed that there were 56 species totally,which belonged to 10 orders,i, e, 26 fami- lies. Of these birds, Passeriformes dominated both in quantities and species. Tree sparrow was the most predominant species in this community. Among the bird population, the residents owned the highest per- centages of quantities and species,and they reached 83.6% and 80.3o//oo respectively. The indices of the spe- cies diversity and the species evenness were 3.36 and 0.83 respectively. Among the six bird habitats, the broad-leaf forest owned the highest value of bird diversity index （3.08） ,while the mixed forest owned the highest value of bird evenness index （0.92）. The results also indicated a low similarity among the different habitats. The highest value of similarity index was found between broad-leaf forest and village, which reached to 0.43. But the lowest value of similarity index occurred between the mixed forest and bush,which was 0.09. Generally,the habitat similarity determined the species similarity. The level of productivity,the bird competition and the human disturbance determined the diversity of species. Among them, the level of productivity of a habitat contributed largely to the bird population there. It was reported that the habitat of the broad-leaf forest and villages had higher productivity and bigger bird population than other habitats.
