1999年1月—2000年4月和2006年7月—2007年6月，用路线法对广州市中心城区5个公园的鸟类组成及多样性进行了调查，共记录到鸟类64种。暗绿绣眼鸟(Zosterops japonica)、白头鹎(Pycnonotus sinensis)和夜鹭(Nycticorax nyctinorax)是优势种。留鸟、冬候鸟和夏候鸟分别占鸟类种数的64.1%、26.6%和7.8%。以9月份记录到的鸟种最多（31种）、7月份和11月份记录到的鸟种最少（均为20种）。公园鸟类的平均遇见率为[(65±5)ind./h]，3月份鸟的遇见率最高[（98±29）ind./h]，1月份鸟的遇见率最低[（35±11）ind./h]，但各月鸟类的遇见率无显著性差异（F ,56=1.35, P= 0.226）。在4、9和12月，迁徙鸟种类最多，迁徙鸟遇见率季节变化明显（F 11，48=3.098，P=0.003）。各公园鸟类的丰度不同，鸟种数与公园总面积显著相关（R=0.905, P=0.035; S=11.02 A0.28，S：鸟类种数，A：公园总面积），即鸟种的数量随公园面积的增大而增加。从鸟类多样性保护和城市用地的角度考虑，广州市公园面积在65 hm2左右较佳。
Bird diversity was surveyed in five urban parks of Guangzhou from January 1999 to April 2000, and from July 2006 to June 2007, using a transect line method. A total of sixty-four bird species were recorded. Japanese White-eye (Zosterops japonica), Chinese Bulbul (Pycnonotus sinensis), and Black-crowned Night Heron (Nycticorax nyctinorax) were dominant species. Residents, winter visitors and summer visitors accounted for 64.1%, 26.6% and 7.8% of recorded bird species, respectively. The greatest number of species was recorded in September (31), the least was recorded in July (20) and November (20). The mean encounter rates of birds was 65±;5 ind./h (±SE), with the highest in March (98±29 ind./h) and lowest in January (35±11 ind./h). There was fluctuation, but it did not differ significantly between months (F 11,48=1.35, P= 0.226). There were a greater number of migratory species in April, September and December. Encounter rates of migratory birds significantly differed between months (F 11，48=3.098，P=0.003). Bird richness differed among the five parks and significantly and positively correlated with the park area (R=0.905, P=0.035), with S=11.02 A0.28 (S：bird species richness, A：park area). This meant that a greater number of bird species occurred in larger parks. Parks with an area of about 65 hm2 were better for avian diversity conservation and land use in Guangzhou.
