Abstract: In order to clarify the types and dynamic regularity of moths in Xixi Wetland Park of Hangzhou， and screen indicative insects that indicate wetland status and the dynamic， the moth population in Xixi Wetland Park was monitored by using light trap method， and speciesabundance curve， diversity index， number of individuals， species richness， and the relationship between the evenness and diversity in the moth community were analyzed from July to October， 2011，and from June to November，2012.The results showed that， there were known 385 species in 27 families， among which Noctuidae， Crambidae and Geometridae were the most. The species abundance relationship served the niche preemption models. Diversity index was not consistent with evenness， but was consistent with species richness. The species of moth in the Xixi National Wetland Park were less， and the community was not stable， which indicated the ecological environment of Hangzhou Xixi National Wetland Park where the moth survive was not stable. Some suggestions of rational utilization and protection of wetland were also put forward in this study.
