摘要

Grey heron (Ardea cimerca) is one kind of the great birds which are often seen in the northeast marsh area of P.R. China, and there are many grey herons to reproduce in Zhalong Nature Reserve from March to August annually. In this paper, through the investigation of the grey heron's nesting habitat and according to the water depth, vegetation type, cover density and plant height of the nesting place, the grey heron's nesting habitat suitability index models are established. The main model is s = (s_1 x s_2 x s_3 x s_4)~(1/4)), where s_1 is the water depth suitability index, s_2 is the vegetation type suitability index, s_3 is the cover density index, s_4 is the plant height suitability index. These models provide a kind of reliable method for evaluating the habitat quality of the grey heron's nesting.
