摘　　要：为了更好地开发利用蛇莓、委陵菜、紫花地丁、红花酢浆草4种观花地被植物,采用人工践踏法进行试验处理,以不践踏为对照,测定践踏处理下4种观花地被植物的SOD、POD、MDA、叶绿素、叶面积、根长、根重等生理生化指标。采用主成分分析法和隶属函数加权法对4种观花植物进行耐践踏性指标的选取和耐践踏性综合评价。结果表明,各生理指标反映耐践踏性能力从高到低为根长>根重>SOD>叶面积>POD>MDA>叶绿素。4种观花地被植物的耐践踏性为蛇莓>红花酢浆草>委陵菜>紫花地丁。For better development and utilization of 4 flower plants of ground cover Duchesnea indica,Potentilla chinensis,Viola philippica,Oxalis corymbosa,artificial trampling was used for the experimental treatment,with no trampling as the controlled trial to measure the change values of 7 morphological and physiological indexes of 4 flower plants of ground cover under trampling treatment,including superoxide dismutase(SOD),peroxidase(POD),malondialdehyde(MDA),chlorophyll,leaf area,root length,and root weight.Principal component analysis and weighted subordinate function was used to select 4 flower plants of ground covers trampling resistance index and comprehensive evaluation of trampling resistance.The results showed that the order of correlation between the selected 7 physiological indicators and tramp resistance was root length>root weight>SOD>leaf area>POD>MDA>chlorophyll.The order of tramp resistance was Duchesnea indica>Oxalis corymbosa>Potentilla chinensis>Viola philippica.
