Based on the arable land fertility of Jingtai County and agriculture partition theories and principles, this research used the method that corresponds partition unit and low-yielding fields partition to partition the agricultural suitability area of the farmland of Jingtai County. The county was divided into five areas, "JingDian first-period" and "JingDian second-period" special economic crops area, Yellow River coastal grain crops l area and economic forest zone, high-lift irrigation dry stock-rearing agriculture and forest area. As a consequence of enlarging the range of using the results of evaluating county farmland fertility, which accordingly provide a possible reference of reasonable layout and land-according suitability of agricultural production of Jingtai County more scientific, systematic and intuitive from three sides containing agriculture, forest and animal husbandry.
