目的调查山西省吕梁山地区有瓣蝇类的种数、物种多样性及区系特征。方法采用生物多样性研究方法及昆虫分类学原理与方法。结果山西省吕梁山地区有瓣蝇类有11科131属408种,蝇科和花蝇科无论在属级水平还是在种级水平,均占有较大优势,分别占该地区已知属数和种数的51.79%、40.20%和62.80%、22.30%;其中特有种14种,占该地区分布种数的3.43%;古北界种176种,古北+东洋界种98种,分别占该地区分布种数的43.14%和24.02%;多样性指数在属级水平和种级水平分别为2.03和1.65。结论山西省吕梁山地区有瓣蝇类具有物种多样性、特有种多样性、区系成分多样性的特点,其区系成分以古北界为主,古北+东洋两界成分相互渗透及其他区系成分共存的特征。
Objective To investigate the species, species diversity and floristic characteristics of flies in Luliang Mountain, Shanxi Province. Methods Biodiversity research methods and insect taxonomy principles and methods were used. Results 408 species of 131 genera belonging to 11 families were found in Luliang Mountain, Shanxi Province. Both Muscidae and Muscidae had greater advantages both in genera and in species level, accounting for the number of known genera and The species number is 51.79%, 40.20% and 62.80%, 22.30% respectively, of which 14 species are endemic, accounting for 3.43% of the total number of species distributed in this area; 176 species belonging to Gubei community and 98 species belonging to Gubei and Toyo region, 43.14% and 24.02% of the total number of species distributed in the region. The diversity index was 2.03 and 1.65 at the genus level and the seed level, respectively. Conclusion There are species diversity, endemic species diversity and floristic composition diversity in the Luliangshan area, Shanxi Province. The floristic composition of the flies in the Lüliangshan area of Shanxi Province is dominated by the Gubeiku area, and the Gubei + Toyo both components penetrate each other and other The characteristics of the coexistence of fauna and flora.
