采用"生产力衰减法",计算了安乡县的土地资源生产潜力和人口承载力.结果表明,安乡县3种主要农作物水稻、油菜、棉花的生产潜力指数分别为66.82%、88.06%和89.06%,尚有2/3～4/5的生产潜力可开发.在温饱型、小康型、宽裕型和富裕型粮食消费水平下的土地资源人口承载力分别为88.54万人、77.48万人、68.87万人和61.98万人;土地资源能够保障全县人口小康水平的粮食消费量,但若要实现富裕型社会发展目标,则必须提高土地生产力水平、并控制人13增长速度.

This research attempted to study systematically the issues of potential land productivity and population carrying capacity in Anxiang county by applying environmental elements step up method. The results showed that there was still 2/3 to 4/5 of the potential land productivity can be developed in Anxiang county. At the current level of land productivity, land resource of Anxiang can satisfy the food grain consumption of whole county population at the level of well-off standard.
