摘　　要：采用层次分析法对草坪品种耐盐能力进行综合评价。结果表明 ,供试草种综合耐盐能力可分为 4组。总评分低于 2 .0属极不耐盐草种 ,2 .0～ 3.0属不耐盐者 ,3.0～ 4.0者属中等耐盐者 ,高于 4.0者属较耐盐草种。在供试草种中 ,草地早熟禾属极不耐盐类 ,高羊茅属中等耐盐类 ,结缕草和匍匐剪股颖的部分品种则属较耐盐类。The result of evaluation on general salt tolerance of 9 turfgrass cultivars by AHP (Analytic Hierarchy Process)showed,the general salt tolerance capacity of experimental turfgrass cultivars can be divided into 4 groups.The general score under 2.0 cultivars belongs to salt very sensible species; the general score between 2.0 to 3.0 cultivars belongs to salt sensible species; the general score between 3.0 to 4.0 cultivars belongs to salt mid-tolerance species,and the general score up to 4.0 cultivars belongs to salt extremely tolerance species.Among the experimental turfgrass cultivars,Kentucky blue grass belongs to very sensible to salt stress type, Tall fescue belongs to salt mid-tolerance type,Zoysia japonica and some cultivars of Bentgrass belongs to salt extremely tolerance type.
