颐和园夜间照明对雨燕影响的试验研究

Studies of the Influence of Lighting on Swift Behavior in Summer Palace

本文对北京珍稀保护动物——雨燕的光照特性、在颐和园的分布作了较为详细的研究;在此基础上,进行雨燕晨昏数量观测,并选用典型室外照明光源进行现场光照实验,初步得出雨燕受人工照明影响的原因及其光照承受照度阈值,提出相关照明控制建议。

In this paper, behavior under lighting and distribution of Beijing swift which is a sort of famous and rare bird in Summer Palace are detailedly studied; pertinent observations and lighting experimentations were carried on near swifts＇ nests in Summer Palace, using typical outdoor lamps and lanterns. Base on the observational data,the mechanism how illumination affect swifts and the illumination intensity threshold which swift could endure are elementary concluded. It is also proposed a lighting swift protection based on the researches.
