摘要
湘黔桂三省区交界地带27县市的年平均气温17℃,降水量达1500mm,植被丰富,调查其茧蜂种类,计13亚科44属84种。分析该地区的茧蜂区系成份,发现属以世界分布属和以纯东洋界分布或东洋界与其它陆地动物区系共有分布为主,种则以古北界分布(14种)或古北界和古北界共有分布(47种)为多,特有种20种,东亚分布型8种。从该特殊小区的温度、植被、地型地貌等因子分析了此类区系成份的成因。
The border area of Hunan, Guizhou and Guangxi is a well-known mountainous region (26° 40"N to 24° 45"N). This region has an annual average temperature of approximately 17°C and abundant rain fall ( 1,500 mm) throughout the year. Due to these conditions, many plant varieties are found in this region. Thirty years of systematic studies on the 13 Braeonidae subfamilies, which encompass 44 genera and 84 species, were recorded. Among the border area of Hunan, Guizhou and Guangxi, the geographical distribution pattems of Braeonidae species were categorized into 4 groups: the Palearctic Region distribution patterns (14 species), the distribution patterns in the Palearetie and Palearctic Regions (47 species), the east distribution patterns (8 species), and the endemic distribution patterns (20 species). Additionally, the causes for these patterns of distribution are presented.
