Abstract: Conducting biodiversity monitoring is the premise of conservation and management. The monitoring of Coleoptera insect
diversity in campus green forest ecosystem can provide support for further scientific management and maintenance of green forest. From
January to November 2018, a survey of Coleoptera insects was conducted in eight typical green space plots in the Ancient City Campus
of Dali University using pitfall traps. A total of 1 615 Coleoptera insects were collected, belonging to 12 families. Among them, the
families Tenebrionidae （42.17%）, Nitidulidae （15.17%）, Melolonthidae （12.07%） and Curculionidae （10.46%） were the dominant
families, while Histeridae （0.25%）, Geotrupidae （0.68%）, Silphidae （0.06%） and Lathridiidae （0.06%） were rare families. The
composition of Coleoptera insect groups among the eight types of green forests showed medium to very high similarity at the family level
（0.64≤q≤1.00）, and the overall diversity of Coleoptera families was relatively low （H = 1.55± 0.23）. The overall abundance of Coleoptera
insects exhibited a bimodal pattern, with peaks occurring in April and September. This bimodal pattern was primarily driven by the
dynamic changes in the abundance of dominant groups. The heterogeneity among different types of green spaces was low, and it is
recommended to increase habitat complexity to enhance the spatial heterogeneity of community habitats.
