Abstract: A gooes-grassland-pool eco-model was established on sandy lands in northern China by growing grass and rearing goose. Matter transference in the grass-goose feces-soil circulation and its effect on soil fertility were investigated.The optimun,goose grazing capacity was determined, and the ecological and ceonomic benefits were evaluated. Soil fertility,and hence, and quality of grass can be improved by goose feces.

Key words: Larix gmelinii, methane flux, nitrous oxide flux, diurnal variation, monthly variation.
