摘要
在本省地形、温度、湿度和植被资源影响下,给多种白蚁的生存提供了良好的生态环境.目前我省共有2种8属38种(其中8种未正式定名).其总的分布趋势为:自北往南呈逐渐递增,分布范围较广,种类亦较丰富,区域性特征明显,能反映出动物地理区划中的古北区和东洋区两大区系的种类分布特点.影响其分布的主要因素为:温度的高低和湿度状况对家白蚁属Coptotermes wasmann的分布关系密切;而降雨量的年均分配量和土壤PH值都制约了散白蚁属Reticulitermes holmgren的分布范围;土壤中的PH值、类型和土层的深度是影响大白蚁属Macrotermes holmgren和土白蚁属Odontotermes holmgren的分布;而象白蚁属Nasutitermesdudly的分布则主要是受到了植被的影响.
There are 38 species of termites recorded in Anhui Province so far. From north to south, the number of species increases, the distributive area extends, and shows regional characteristic. This distributive trend demonstrates the characters of geographical location, humiture, physical and chemical properties of soil and vegetative resources of this province.
The termite fauna in Anhui includes both oriental and paleoarctic species. To the south of Huaihe River oriental species are dominant, with some paleoarctic species mixed. There is a clear northern boundary for each genus or species, it is related to humiture, soil and vegetation factors, but their distributive areas often overlap in southern Anhui and shows a complexity. According to their distributions, the main factors affecting the distribution of Coptotermes is humiture, for Reticulitermes are the amount of mean annual precipitation and PH of soil, for Odontotermes and Macrotermes are PH, structure and depth of soil, and for Nasutitermes, their hosts-vegetations.
