Abstract: In this paper, the main factors affecting the habitat selection of red-crowned crane were grouped into water body, food, shelter, and disturbance, which were classified into several classes to determine the habitat type. The survey was conducted in two seasons, i.e., migration (from mid October to late November) and wintering (from first December to late January). The sampling sites were chosen based on red-crowned crane’s living behavior, and their location was designated by GPS to ensure the uniformity of their distribution. The results showed that in migration season, the main factor affecting habitat selection was disturbance, and the optimal habitat of red-crown crane had the characters of non-disturbance, shallow water body, and low vegetation cover. In wintering season, the main factor affecting habitat selection was food, and the optimal habitat of red-crown crane had the characters of non-, light- or mid-disturbance, shallow water body, abundance of flesh-food, and low vegetation cover.
