贵州德江楠杆保护区昆虫种类及区系分析

Species and Faunal Analysis on Insects in Guizhou Dejiang Nangan Nature Reserve

摘要: 为掌握德江楠杆自然保护区的昆虫种类及区系特点， 2016年 4-11月，采用样线踏查法、网捕法、灯诱法对楠杆自然保护区内昆虫进行了三次采集，对其进行室内鉴定，结合相关文献，对该保护区内昆虫种类进行统计与分析。结果表明：楠杆自然保护区昆虫种类有 464种，属 15目；在世界动物地理区划中具有典型东洋界特征，与古北界关系最紧密，与新热带界关系最疏远；在中国动物地理区划中具有典型的华中区特征，与西南区关系最密切，与青藏区关系最疏远；结论符合该保护区的地理位置特征。可针对昆虫种类及区系分布的特点对昆虫进行高效保护，提高对昆虫资源的利用，提高保护区的可持续性发展。
