天目山自然保护区昆虫区系研究

针对天目山4纲30目3729种昆虫，分析了该区的昆虫区系特征、区系联系和区系起源。结果表明，天目山昆虫区系特征为：东亚成分为主体，昆虫模式标本丰富，种类富庶，区系成分古老独特，垂直分布较明显。天目山昆虫与南部邻近地区关系较紧密，尤以与西部、南部的关系密切，而与北方的联系较小，特别是与西北干旱区系的关系极小。天目山昆虫区系起源的主要成分为自晚侏罗纪形成的我国东部高原古昆虫在天目山定居发展起来。昆虫区系从热带属性逐渐演化为亚热带山地区系。

Study on Insect Fauna of Tianmushan National Nature Reserve

From 1998 to 1999, a survey on the insect fauna and their resources of Tianmushan National Nature Reserve was carried out. 3729 insect species of the reserve have been classified into 4 faunistic categories. The results indicate that the East Asia components forming the main part of the insect fauna in the reserve. Similarities to fauna of various provinces and regions of China, of adjacent countries have been analysed. The result indicates that Tianmushan is more similar to southeast and west provinces and regions, and to northeast and southeast countries. The fauna therefore has more relation with the tropical and temperate faunas of China, and little with the dry faunas of Northwest China. So the insect fauna of Tianmushan should belong to the damp and hot monsoon type. Discussion: insect fauna of Tianmushan began middle Jurassic period 150 million years ago. Fauna of insects had undergone fast development, more and more new taxa appeared. The fauna had more relation with east and west. In Tertiary period, the insects of Tianmushan transformed from a plateau tropical fauna into a lower mountain subtropical one.
