南昌城市生态站站点冬季鸟类资源多样性

Diversity of Winter Bird Resources in Nanchang Urban Ecosystem Research Station

为了明确南昌城市生态站城区和近郊监测站点冬季鸟类资源多样性状况,通过样线法对南昌城区和近郊公园冬季鸟类资源开展调查。结果表明:在近郊公园省林科院内调查鸟类有40种,优势种为麻雀(Passer montanus)、珠颈斑鸠(Streptopelia chinensis)2种,艾溪湖湿地公园记录鸟类37种,优势种为白头鹎(Pycnonotus sinensis)、麻雀(Passer montanus)2种。香农-威纳指数(Shannon-Wiener)指数测度江西省林业科学院鸟类物种多样性(H')为3.168,均匀度(J)为0.853。艾溪湖湿地公园鸟类物种多样性(H')为3.249,均匀度(J)为0.914。省级保护鸟类在城郊公园中占本区域调查鸟类种类的26.83%,在城区公园中29.73%。丰富生境类型是提高鸟类多样性的有效措施。因此,在城市鸟类多样性保护的过程中,除了从鸟类栖息地生境考虑,还要结合单个绿地在城市环境中的位置进行考量。

In order to clarify the diversity of bird resources in winter at the urban and suburban monitoring stations of Nanchang Urban Ecological Station,the bird resources in winter in Nanchang urban and suburban parks were investigated by transect method.The results show that:Forty-one species of birds were investigated in the Academy of Suburb Park,among which the dominant species were Passer montanus and Streptopelia chinensis,thirty-seven species of birds were recorded in AiXiHu Wetland Park,of which Pycnonotus sinensis and Passer montanus were the dominant species.The bird species diversity(H')and evenness(J)measured by Shannon-Wiener index in Jiangxi Academy of Forestry were 3.168 and 0.853 respectively.In Aixi Lake Wetland Park,bird species diversity(H')was 3.249,and evenness(J)was 0.914.Provincial protected birds accounted for 26.83%of the surveyed bird species in the suburban parks and 29.73%in the urban parks.Therefore,in the process of bird diversity protection in the city,in addition to the consideration of bird habitat,the location of a single green space in the urban environment should be taken into consideration.
