摘要
采用层次分析法，确定了牧草抗旱性综合评价体系中各类指标及其指标变量的权重系数，并根据甘肃省１４个紫花苜蓿地方品种的抗旱性指标测定资料，对牧草的６类抗旱性指标中的２１个指标变量进行了数学分析，得到牧草抗旱性的综合评价值，对各品种的抗旱性强弱进行了排序。
21 drought resistance indexes variables of 6 drought resistance indexes of forage grass were studied. The relations between several index variables and drought resistance were explained, the weight coefficient of indexes and index variables in comprehensive evaluation of forage grass were gotten through Analatical Hierarchy Process (AHP), the order of 14 Medicago sativa L.in drought resistance was gotten.
