In order to understand the occurrence status,population structure and distribution of longicorn beetles in Lishan National Nature Reserve in south of Shanxi province,China.Four habitat types(Broad-leaved forest belt.Co-niferous and broad-leaved forest belt.Sparse forest shrub belt.Shrub farming belt.)were selected from four pre-cincts(Xiachuan precincts.Ligeda precincts.Lishan precincts.Dahe precincts.)in the nature reserve to investigate the diversity of longicorn beetle.The results of the diversity analysis show that the reserve of the longicorn beetle in-sects belonging to 120 species of 81 genera,in 6 subfamilies,accounting for 12.16%and 3.05%of the known gene-ra and species in China respectively,among which Cerambycinae has the largest number of species and Lepturinae has the largest number of individuals,and fifty-six species are newly recorded to Shanxi province.According to the coefficient of genus-species ratio,single-species genera account for a large proportion,implying that single-species are dominant within the genus of Cerambycidae in this reserve.Diversity analysis shows:Lishan precincts has the highest richness index,The order from high to low values in the Pielou's eveness index and Shannon-Wiener index is Ligeda precincts>Dahe precincts>Lishan precincts>Xiachuan precincts,the Simpson index is Xiachuan precincts>Lishan precincts>Dahe precincts>Ligeda precincts.Sparse forest shrub belt has the highest richness index,The or-der from high to low values in the Pielou's eveness index and Shannon-Wiener index is Shrub farming belt>Sparse forest shrub belt>Coniferous and broad-leaved forest belt>Deciduous broad-leaved forest belt,the Simpson index is Deciduous broad-leaved forest belt>Coniferous and broad-leaved forest belt>Sparse forest shrub belt>Shrub farm-ing belt.The faunal distribution pattern is mainly characterised by species shared by the Palearctic and Oriental,ac-counting for 84.17%of the species in the region.There are a total of 30 zone types belonging to the geographical di-vision of insects in China,with North China and Central China as the main body,and closely related to Southwest China.
