摘要:

近年来我国风力发电发展迅速, 已有研究发现风电工程会对鸟类多样性产生不同程度的影响。然而, 过去的研究多以区域内鸟类常规调查为主, 未直接对风机致死鸟类进行长期系统的调查监测, 也未进一步探究风机致死可能的方式和原因, 从而难以根据风机致死鸟类的实际情况提出有针对性的防范措施和应对方法。本文以江苏盐城滨海地区风电场为例, 基于2020年10月至2021年9月共22次连续的调查监测, 应用尸体搜索法调查了研究区域内风机致死鸟类的情况。结果表明: (1)风机下发现的死亡鸟类有8目10科12种, 死亡鸟类主要为留鸟或已在研究区域内繁殖的种类, 占死亡鸟类种类的66.7%; (2)风机下共发现死亡鸟类41只, 环颈雉(Phasianus colchicus)死亡数量最多, 有19只, 大部分位于农田及农田防护林中; 夜鹭(Nycticorax nycticorax)和白鹭(Egretta garzetta)死亡数量也较多, 共11只, 主要位于鱼塘中; (3)通过对风机下死亡鸟类的情况分析发现, 在风机基座比风机扇叶造成的碰撞致死情况多。最后, 本文提出了减缓风机对鸟类影响的措施和建议, 包括持续开展鸟类监测, 及时开展风机下生境的治理, 加强鸟类相关驱避技术装备研发等, 为我国风电与生态环境保护之间的协调发展提供参考。

Abstract

Aims: In recent years, wind power generation has been developing rapidly in China, and studies have found that wind power projects have varifying degrees of impact on bird diversity. However, previous studies primarily adopted traditional survey methods of birds in the region, without conducting long-term systematic monitoring of birds killed by wind turbines. Little is known about the possible causes of wind turbine mortality. Thus, it is difficult to propose targeted mitigation measures based on the actual causes of birds being killed by wind turbines.

Methods: In this paper, our study area was the wind turbines factory in the coastal area of Yancheng, Jiangsu Province. The carcass search method was applied to investigate the wind turbine mortality of birds in the study area. We conducted a total of 22 consecutive surveys from October 2020 to September 2021 to explored bird mortality from wind turbines.

Results: (1) There were 12 species in 8 orders and 10 families that were found dead under the wind turbines. The dead birds were primarily native birds or species that breed in the region, accounting for 66.7% of the dead bird species. (2) A total of 41 dead birds were found under the wind turbines. The most common were ring-necked pheasants (Phasianus colchicus) at 19 individuals, which were generally found in farmland or agricultural protection forest. Dead night herons (Nycticorax nycticorax) and egrets (Egretta garzetta) were also common, with 6 and 5 individuals found, respectively, and were generally found in near fishponds. (3) Based on the injuries of the dead birds, it was concluded that the bases of the wind turbines caused more collisions resulting in death than the fan blades.

Conclusion: According to our study, we proposed the following suggestions to mitigate the impact of wind turbines on birds. These suggestions include continuous bird monitoring, controlling habitats under wind turbines, and strengthening the research and development of bird-related repellent technology and equipment. We hope this study can provide a reference for the coordinated development between wind power and ecological environmental protection in China.
