摘要：为了解广州南沙湿地鸟类迁徙规律,揭示鸟类整体迁徙动态变化,于2014年1月至2018年12月,连续在每月下旬日落前3 h采用样点法和样线法对南沙湿地公园鸟类群落多样性进行调查。结果显示:1)2014—2018年共记录到鸟类139种,以冬候鸟为主。2)鸟类物种数年际波动较大,丰富度年际变化不明显,即鸟类种类在逐渐增加的同时,个体数量趋于稳定。3)鸟类月度变化呈现明显的候鸟迁徙规律,越冬期急速上升,繁殖期平缓。越冬水鸟迁飞时间有提前的趋势,且在富有食物来源的浅水滩涂地和在无瓣海桑等高大茂盛的红树林群落有更多种类与数量的水鸟分布。最后,建议在注重绿化连续性和整体性的同时,保护和管理鸟类的栖息环境,适当扩大滩涂地面积,增加红树林种植面积以及合理地围垦,科学维持浅水滩涂和红树林种植面积比例,吸引更多越冬候鸟。
As an important land and water transition zone on Earth,wetlands are good places for birds to breed and roost.Bird monitoring has become an important index for assessing the biodiversity and ecological environment of a region.Nansha Wetland Park in Guangzhou is rich in biological resources and provides an important resting and wintering ground for global migratory birds as it is located on their migration route from East Asia to Australasia.To understand the migration patterns and annual dynamic changes of birds in the Nansha Wetland Park,line-and point-transect surveys were conducted to collect bird species and abundance data from January 2014 to December 2018.First,our results showed that 139 birds were recorded during the study period,of which migrant species were dominant.Combined with the available literature,a total of 186 bird species were recorded,belonging to 17 orders and 49 families.Of these bird species,165 are under various levels of protection.Second,while the interannual changes in bird abundance were substantial,those of bird species richness were not,indicating that bird species tended to reach maximum abundance in bird communities.When compared to bird abundance in 2015,the number of individuals was relatively stable in other years of investigation,and the number of investigated species was the highest in 2017.Finally,monthly changes in bird species were in accordance with the annual rhythms of migration.Specifically,bird species richness increased rapidly during the wintering period,but remained constant during the breeding period.In addition,the migration time of waterbirds tended to increase over time.This may be related to a warming climate that prompts birds to migrate earlier.Differences in habitat patches are important influencers of bird feeding habits,and thus bird distribution and habitat.Among the habitat patches investigated,birds were primarily distributed in shallow tidal flats with rich food sources and in tall and lush mangrove communities,such as those containing the species Sonneratia apetala.Notably,the number of Platalea minor,a key indicator bird species,has increased steadily,with an increase of 346.15% from 26 in 2014 to 116 in 2018.The annual and monthly dynamic changes of birds in different areas showed subtle changes in individual numbers but generally showed a stable trend,which may be related to the environmental capacity of the habitat.The number of species and individuals that can be sustained by the environment tended to be saturated;that is,the maximum number of species that can be accommodated by the Nansha Wetland Park.Taken together,these findings suggest that bird species diversity could be promoted by expanding the area of tidal flats,increasing the planting area of mangroves,reasonably reclaiming wetlands,and maintaining the proportion of shallow water tidal flats and mangroves.
