Abstract: In this paper, the distribution patterns of domestic aniamls and birds varying with land use and population density in various animal husbandry regions of Anhui province are studied and the grey models of their distribution density are established. From north to south of their province, the upland area decreased from 54 to 2%, forest land area increases from 5.5 to 62%, and low land and water body mainly distribute in hills and plains. Population density has a greater influence on distribution density of domestic animals and birds, the correlation coefficient being 0.65-0.83. The percentage of upland area is the most important factor influencing distribution density of domestic herbivorous animals, with a correlation coefficient of more than 0.9 Water body area has a greater influcuce on domestic bird density than other affecting factors. The fitting error of established models to practieal conditions is about 2%.
