扰动因子对龙凤湿地鸟类影响的研究

The Research of Effects of Disturbance Factors on Birds in Longfeng Wetland

为了研究湿地生态系统的扰动因子对生活其中的鸟类种类多样性的影响,进而保护湿地生态平衡和保护湿地鸟类多样性,于2009年3月—2012年6月,采用样线法和样点法对龙凤湿地鸟类进行了研究。结果显示,龙凤湿地的鸟类种类由16目33科减少到13目20科,种数由142种减少到46种。随着城市湿地自然因子和湿地污染、湿地水资源利用过度、湿地景观破碎化、噪声和电磁辐射污染等人为扰动因子的变化加剧,龙凤湿地的鸟类种类明显减少。扰动因子的变化,是湿地鸟类减少的重要诱因。减少扰动因子对龙凤湿地鸟类的影响,保护湿地鸟类,任务非常紧迫。

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.
