Abstract:

In order to probe the wintering habitat selection of Mergus squamatus. The methods of fixed-spot observation, GPS positioning, plot sampling measurement, factor analysis, and χ2 test were used to investigate Merganser’s wintering habitat in Jiangxi Province. The results showed that: the habitat type choice had the characters of universality and particularity. The key elements for the wintering habitat selection were vegetation cover, water environment, terrain factor, human disturbance factor. The wintering habitat selection of Mergus squamatus was prior to the area which have low altitude (50-60 m, 78.6%), low gradient (<0.36, 98.6%), low noise distribution (<40 dB, 89.2%), and far away from village ( 6-12 km, 71.9%), middle far away from village( 6-12 km, 71.9%), road (1-2 km, 79.4%), and forest edge (<50 m, 85.4%).
