2005～2009年广州南沙湿地鸟类的群落结构及数量动态

Community Structure and Quantity Dynamics of Birds in Nansha Wetland,Guangzhou(2005～2009)

2005～2009年对南沙湿地鸟类群落开展了监测。2005年发现50种,隶属12目26科,全年记录到总数3548只;2006年发现57种,隶属12目28科,全年记录到总数5488只;2007年发现64种,隶属12目31科,全年记录到总数5063只;2008年发现69种,隶属12目32科,全年记录到总数4251只;2009年发现73种,属12目32科,全年记录到总数4776只。鸟类群落的数量不同月份有显著的变化,说明南沙湿地秋冬季是南迁北徙鸟类重要的觅食地和栖息地。鸟类群落的种类和数量每年有增加的趋势,2008年和2009年比2005年分别增加19种和23种。鸟类群落的多样性每年在增长,2005年为2.9608,2006年为2.9869,2007年为3.1624,2008年为3.2544,2009年为3.2776,2008年和2009年比2005年分别增长了9.91%和10.7%。从2005～2009年鸟类群落的种类和数量来看,目前南沙湿地开放旅游由于限制了游客数量还没有影响到鸟类种类、数量和栖息地。

The bird community of Nansha Wetland in 2005 -2009 was investigated. 3548 birds belonging to 50 species, 26 families, 12 orders were recorded in 2005. 5488 birds belonging to 57 species, 28 families, 12 orders were recorded in 2006. 5063 birds belonging to 64 species, 31 families, 12 orders were recorded in 2007. 4251 birds belonging to 69 species, 32 fam- ilies, 12 orders were recorded in 2008. 4776 birds belonging to 73 species, 32 families, 12 orders were recorded in 2009. The significant variation of the bird community quantity in different months suggests that Nansha Wetland was a feeding site and habitat for migratory birds in autumn and winter. The bird species and quantity increased each year. Compared to 2005, the bird species had an increase of 19 in 2008 and 23 in 2009. The diversity of the bird community also increased every year, which was 2.9608 in 2005, 2.9869 in 2006, 3. 1624 in 2007, 3. 2544 in 2008, and 3. 2776 in 2009. Compared to 2005, the diversity increased by 9.91% in 2008 and 10.7% in 2009. From the perspective of species and quantity of the bird community from 2005 -2009, opening Nansha Wetland to tourism had not yet impacted the bird populations there.
