[Distribution of Formica cunicularia mound and related affecting factors on mobile dune in Horqin sandy land].
Taking the typical mobile dune in Horqin sandy land as test object, the density, diameter, and coverage of Formica cunicularia mounds on different land forms were investigated by quadrate method, with the spatial distribution of F. cunicularia mounds and the effects of topography and soil property on F. cunicularia nest-building activities discussed. The results showed that the density of F. cunicularia mounds decreased in the order of ridge > leeward slope > windward slope, while the diameter and coverage of the mounds were in the order of ridge > windward slope > leeward slope and conditioned by mound density. The spatial distribution of F. cunicularia mounds was in random pattern. Topography and soil property co-affected the nest-building activities of F. cunicularia.
