我们在一个蝙蝠群落周围的78个地点进行了声学调查，以研究大马蹄蝠对栖息地的季节性使用模式。每个季节测定昆虫数量和温度。通过分析粪便成分来评估蝙蝠的饮食。大马蹄蝠倾向于在阔叶混交林和阔叶与针叶林混交林中觅食，很少在针叶林中觅食。6 ~ 9月，阔叶混交林和林间林中的蝙蝠活动明显减少。不同生境的利用频率存在显著的季节差异。日栖距离对蝙蝠活动的影响仅在6月和7月显著。大马蹄蝠的饮食明显以鳞翅目和鞘翅目为主，并随季节有所变化。大马蹄蝠对栖息地使用的季节性变化可能取决于随空间和时间波动的资源可用性。这些结果对该蝙蝠物种的保护具有重要意义。杂乱阔叶林和混交阔叶林是重要的保护对象。应鼓励种植和维持阔叶林或混交林，而不是以非原生纯针叶林重新造林。
Abstract We performed acoustic surveys at 78 sites around one bat colony to examine seasonal patterns of habitat use by greater horseshoe bats. Insect abundance and temperature were determined in each season. Bat diets were assessed by analysing faecal composition. Greater horseshoe bats tended to forage in mixed broadleaved and mixed broadleaved and coniferous woodland and were rarely found foraging in coniferous woodland. Bat activity in mixed broadleaved woodland and woodland glades significantly decreased from June to September. There were significant seasonal differences in the frequency of utilization of different habitats. Distance from the day roost had significant effects on bat activity only in June and July. The diet of greater horseshoe bats was clearly dominated by Lepidoptera and Coleoptera, with some variations with seasons. The seasonal variation of habitat use by greater horseshoe bats probably depended on resource availability that fluctuates over space and time. These results have important implications for the conservation of this bat species. Cluttered broadleaved woodland and mixed broadleaved woodland constitute an important target for conservation. Instead of reforestation with the non-native pure coniferous woodland, planting and maintaining broadleaved forests or mixed forests should be encouraged.
