The characteristics of urban green land diversity is an important subject of urban ecosystem research under the background of rapid urbanization and global climate change. In this study, the characteristics of nematode communities were studied under different green land types. Forty-six genera were identified for nematode. Different types of urban green land types significantly changed the indices of nematode biodiversity and nematode function diversity (P<0.05). Scenic area green land had the highest of nematode biodiversity, followed by park green land, and residential green land was the lowest. The maturity index of free living nematode and the channel ration of nematode were the lowest in the road green land, increased in the residential green land and park green land and reached the highest value in scenic area green land.Aphelenchoides, Cylindrolaimus and Epidorylaimus were the indicator species for road green land, Bastiania for park green land, while Leptonchus, Monhystera and Clarkus for scenic area green land. The significance of nematode on the ecosystem of urban green lands was further revealed, and the theoretical basis for the protection of urban biodiversity was provided.
