广西黔江弩滩段鸟类群落结构及其多样性

【目的】掌握广西黔江弩滩段鸟类群落结构的组成特点及其多样性在不同生境和不同季节的变化特征,为后续系统开展广西河流生态系统鸟类群落研究提供参考。【方法】于2015年3月~2016年2月,分春、夏、秋、冬4个季节进行野外调查,在研究区域的固定样带及样点对各季节的鸟类种类、数量、空间分布及其活动情况等进行详细调查,并根据调查记录的鸟类种类、数量、生境状况等信息,计算各生境内鸟类的丰富度、优势度、物种多样性和均匀度等指数。【结果】经野外调查,广西黔江弩滩段现场共记录到鸟类37种,隶属9目22科,其中留鸟24种(占64.9%)、冬候鸟8种(占21.6%)、夏候鸟2种(占5.4%)、旅鸟3种(占8.1%)...

Summary:【目的】掌握广西黔江弩滩段鸟类群落结构的组成特点及其多样性在不同生境和不同季节的变化特征,为后续系统开展广西河流生态系统鸟类群落研究提供参考。【方法】于2015年3月~2016年2月,分春、夏、秋、冬4个季节进行野外调查,在研究区域的固定样带及样点对各季节的鸟类种类、数量、空间分布及其活动情况等进行详细调查,并根据调查记录的鸟类种类、数量、生境状况等信息,计算各生境内鸟类的丰富度、优势度、物种多样性和均匀度等指数。【结果】经野外调查,广西黔江弩滩段现场共记录到鸟类37种,隶属9目22科,其中留鸟24种(占64.9%)、冬候鸟8种(占21.6%)、夏候鸟2种(占5.4%)、旅鸟3种(占8.1%)。鸟类群落的优势种(频率指数RB>10)为矶鹬、金腰燕、白鹡鸰、田鹨、红耳鹎、白头鹎和麻雀,其余为普通种或稀有种。在5种生境中,鸟类多样性指数(H')和均匀度指数(E)均表现为林地生境>农田生境>河漫滩生境>河岸生境>江面生境。广西黔江弩滩段林地生境与农田生境的鸟类相似性指数最高,均为0.68;鸟类种类及数量的季节变化明显,表现为冬季的鸟类种类最多(35种)、夏季最少(26种),春季的鸟类数量最多(4394只)、夏季最少(2334只)。【结论】广西黔江弩滩段鸟类群落结构特点为林鸟所占比例远高于水鸟,留鸟构成鸟类群落的主要成分,鸟类多样性的季节变化明显,以夏季鸟类的种类及数量最少。大藤峡水利枢纽工程建设将对广西黔江弩滩段河流湿地生境依赖性较强的水鸟产生较大影响,但不会对适应农田生境、林地生境的林鸟造成较大影响,库区生境难以吸引游禽栖息活动。
Bibliography:Objective】The purpose of this study was to survey the composition characteristics of avian community structure and its diversity variation characteristics in different habitats and seasons in Nutan section of Qianjiang River inGuangxi,and provide reference for subsequent research on avian community in Guangxi river ecosystem.【Method】The fieldwork was conducted from March,2015to February,2016,and divided into4seasons:spring,summer,autumn,and winter.The species,number,spatial distribution,and activities of birds in different seasons were investigated in the fixed transect and sample sites.The richness,dominance,species diversity and evenness index of birds in different habitats were calculated based on the information of birds,species and habitats.【Result】Through field investigation,37species were recorded in Nutan section of Qianjiang River in Guangxi,which belonged to22families and9orders.Among them,24species were resident birds(accounted for64.9%),8winter migrants(accounted for21.6%),2summer migrants(account
