摘　　要：本研究选用密度、质地、颜色、盖度、均一性、高度、绿期、草坪组成、成坪速度等9项指标,采用层次分析法(AHP)及模糊数学综合评判方法,对杨凌栽植的4种冷地型草坪草的观赏特性进行了综合评价。将这9项指标作为评价指标进行数量化测定,采用层次分析法(AHP)通过构建权重矩阵,对几种观赏草坪配以指标权重,然后结合模糊数学综合评价方法,给出草坪质量的评价等级。从而在观赏效果方面为杨凌示范区建坪草种的选择提供一些参考。实验结果表明杨凌地区冷地型草坪草观赏效果好坏程度依次是匍匐翦股颖、高羊茅、草地早熟禾、黑麦草。养护管理水平不够是这些草坪普遍存在的问题,影响草坪的观赏效果。Four kinds of cool-season turf grasses were compared in terms of 9 factors：their density,texture,color,coverage,evenness,height,period of green,components as well as the speed of turf formulation.AHP and fuzzy mathematics evaluation were applied for quantity the factors and evaluate the quality of turfs.The experiment showed that Agrostis stolonifera has the best quality of ornamentation,followed by Festuca arundinacea,Poa pratensis and Lolium perenne is the lowest one.The general problems for all kinds of turf is inadequate management and maintenance.
