The Impact On The Avian Community Of Human Disturbance During The Restoration Period In Zhalong Wetland

According to the disturbance status of Zhalong Wetland, we had classified four regions were: severe disturbance intensity,intermediate disturbance intensity, light disturbance intensity and non-disturbance intensity.Field surveys were conducted in the Zhalong Wetland from April to May in 2006 and 2007. The results shows that there are 54 avian species, belonging to 20genera, 7 families, 21 species of Iosmopolitan, and 33 species of Palaearctic realm,36 species of summer breeders, 9 species of migrants and 9 of residents among them.The significance testing results of the avian community composition characteristics index among 4 areas,showed that different index of 4 areas have different impacts on the human disturbance intensity. Biomass in the different areas had the largest significance(P<0.05), there was significant relationgship between the avian community with the intensity of human disturbance. The significance of species richness had taken second place(P < 0.05).The Shannon-Wiener index and Pielou evenness index was not evident significance among the 4 groups of the avian community,which had relatively less relationship with the intensity of human disturbance.The differences testing results for the avian community composition among the different habitat types with the 4 intensity showed that different habitats types have different impacts on the human disturbance intensity. The impact degrees are as following: reed marshes > sedge marshes >meadow grassland> lakes.
