摘  要:
遗鸥(Larus relictus)在国际上是濒危鸟种,繁殖地在内蒙古盐沼湿地,繁殖地的选择与觅食行为密切相关。从2005年至今连续多年对该盐沼湿地遗鸥进行调查,结果表明:在内蒙古沙漠盐沼湿地,豆娘成虫和幼虫是遗鸥整个繁殖季的主要食物,摇蚊幼虫起重要的食物补充作用,由于当地生态环境恶化,水体p H值9.59已临近豆娘生存的p H值上限9.62,豆娘濒临消失,遗鸥将失去其在繁殖地的主要食物。

摘  要:
In the world Larus relictus is an endangered species. It's breeding ground is in the salina wetland in Inner Mongolia. The choice of breeding ground is closely related to the foraging behavior. We have studied Larus relictus in the salina wetland for many years since 2005. Results showed that the Caenagrion imagoes and larvae are the main food of Larus relictus in the breeding season in Inner Mongolia desert salina wetland. Chironomidae larvae is an important food supplement for Larus relictus. Because of the local ecological environment deterioration,the water p H value 9. 59 will reach the limit of Caenagrion survival9. 62. If Caenagrion disappears,Larus relictus will lose its main food in breeding ground.
