摘　　要：鸟类是自然生态系统的重要组成部分。广西位于重要的候鸟迁徙途径区域,候鸟资源丰富,识别出鸟类迁徙通道区域对于进一步做好候鸟保护工作具有重要意义。研究重点考虑秋季10月、11月气流对候鸟迁徙路径的影响;考虑1000 m以下高度飞行的候鸟易在广西停留,气流轨迹密度计算设置H+300、H+900两个计算模式;综合考虑地形、自然生态环境等因素影响,以地理信息技术为支撑,对广西秋季候鸟的迁徙通道进行划分研究,识别出广西陆域风电开发建设应重点关注候鸟迁徙通道县域,以期地方在大力发展风电的同时,能协调好风力资源开发与候鸟资源保护的关系。Birds are an important part of natural ecosystem.Guangxi is located in an important migratory routes area with abundant migratory bird resources.Identifying the area of bird migration passage is of great significance for further protection of migratory birds.The study focused on the effects of airflow on the migration path of migratory birds in October and November in autumn.Considering that migratory birds flying at altitudes below 1000 m are likely to stay in Guangxi,the airflow trajectories density calculation was set to two calculation modes:H+300 and H+900.Considering the influence of topography,natural ecological environment and other factors,and supported by geographic information technology,this paper divided and studied the migration routes of autumn migratory birds in Guangxi,and identified that the development and construction of land wind power in Guangxi should pay more attention to the county areas of migratory birds.It is expected that while vigorously developing wind power,local governments can coordinate the relationship between the development of wind resources and the protection of migratory birds resources.
