摘要：

开展耕地地力评价是测土配方施肥补贴项目的一项重要内容，是摸清耕地资源状况，提高耕地利用效率，促进现代农业发展的重要基础工作。在景泰县县域耕地地力评价结果的基础上，依据农业分区的理论及原则，运用分区单元与中低产田分区对应的方法对景泰县耕地进行了农业适宜性分区。将全县耕地划分为景电（一、二期）特色经济作物区、黄河沿岸粮食作物与经济林区和高扬程提灌干旱畜牧农林区。农业适宜性分区结果不但扩充了县域耕地地力评价的应用范围，而且从农、林、牧三方面科学的、系统的、直观的为景泰县农业生产合理布局、因地制宜及决策制定提供了可靠参考。

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.
