摘要: 本文采用灰色系统理论与方法,研究了安徽省及其各畜牧区的家畜(禽)分布随土地利用类型及人口密度的变化规律,建立了家畜(禽)分布密度的灰色静动态模型。结果表明,安徽省由北向南旱地面积从54%下降到2%;林地则由5.5%上升到62%;水田和水面主要分布在江淮丘陵和沿江平原区。人口密度对各类畜禽的分布密度有较大的影响,关联度为0.65-0.83;旱地比率是影响草食动物分布密度的最主要因素,并联度高达0.9以上;水面的比重对家禽密度的影响高于其它因子。用土地利用类型因子及人口密度所建立的模型,对家畜的实际分布密度及其变化规律的拟合误差在2%左右。

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%.

Key words: Land use pattern, Animal distribution density, Grey model
