人类活动对三江平原东北部湿地鸟类的干扰

Effects of Human Disturbance on Wetland Birds in the Northeast of Sanjiang Plain

人类的开垦和开发活动使湿地鸟类遭到严重干扰和破坏。三江平原湿地鸟类的主要人为干扰方式有农业开垦、城市开发、水利工程、采矿、道路与桥梁的修建和旅游等,利用层次分析法来定量分析人类活动的主要干扰方式对湿地鸟类的影响。研究结果表明,研究区内人类活动对湿地鸟类的干扰是由东向西、由北向南逐渐增强,鸟类丰富度与干扰度之间呈抛物线关系。

Wetland birds in Sanjiang Plain were severely disturbed and destroyed because of blindly reclamation and exploitation of wetland resources. The main types of disturbances include agricultural reclamation, urban exploitation, water conservancy, mining, building of road and bridge, tourism, and so on. Effects of the main types of human disturbances on wedand birds were analysed by the analytic hierarchy process. Result showed that wetland bird richness presented a parabola relation with disturbance degree. The disturbance degree gradually increased from east to west and from north to south in San-jiang Plain.
