西双版纳地区蝙蝠物种多样性夜间分布模式

Night distribution pattern of bats species diversity in Xishuangbanna

为探究热带蝙蝠物种多样性的夜间变化,对西双版纳热带雨林地区蝙蝠活动进行探测,分析了夜间不同时间段和不同季节相同时间段内蝙蝠物种多样性的变化规律。结果表明,蝙蝠物种多样性夜间分布除18:00-20:00与20:00-22:00、22:00-00:00与00:00-02:00、00:00-02:00与02:00-04:00时间段外差异性显著。在季节变化中,秋冬季蝙蝠物种多样性第一次高峰出现时间早于春夏季1 h。

In order to explore the night variation of bat species diversity in Xishuangbanna,acoustic monitoring detector was used to probe bat activities,analyzed the variation of bat species diversity in different time at night during a year.The results showed that the distribution of bat species diversity at night was significantly different,except 18:00-20:00 and 20:00-22:00,22:00-00:00 and 00:00-02:00,00:00-02:00 and 02:00-04:00.In the seasonal variation,the first peak of bat species diversity in autumn and winter is one hour earlier than that in spring and summer.
