Abstract: In order to study the influence of the disturbance factors of wetland ecosystem on the bird diversity, and protect the wetland ecological balance and bird diversity. The author studied the birds in Longfeng wetland by using transect method and sample point method from March 2009 to June 2012. The results showed that: the bird species in Longfeng wetland decreased from 16 to 13 in families, 33 to 20 in orders and from 142 to 46 in species. The bird species in Longfeng wetland decreased significantly on account of the polluting of the wetland and its natural factors, the excessive utilizing of water resources, the fragmenting of wetland landscape and human disturbance factors, such as noise and electromagnetic radiation pollution. The change of the disturbance factors gave rise to the decrease of wetland birds. It was very urgent that reducing the influence of disturbance factors, and protecting wetland birds.
