Abstract: Based on the longterm monitored data on birds and shortterm field observation, in combining with the environmental characteristics of Yancheng National Rare Waterfowls Nature Reserve, this paper analyzed the influence of wind power field on the birds in the Reserve. Owing to the occupation of avian habitat, the establishment of wind power field had indirect effects on the inhabiting behaviors and foraging of birds, but the impact was relatively small. The slow fan speed and the higher altitude at which the birds fly led to a lower collision risk between fan and birds. In order to protect the safety of birds and their normal life, some countermeasures such as rational distribution of wind power fields, establishment of bird observation stations, and coordination of developing and constructing regional beach and adjacent areas were proposed.
