摘　　要：通过观察8份链荚豆种质草坪密度、均一性、颜色、耐践踏性、草坪盖度等5个坪用价值相关指标,根据草坪不同功能确定指标权重后评分,按照分值进行坪用价值综合评价。结果表明:8份链荚豆种质中,评分最高的是湛江圆叶,得分最低的是儋州尖叶。参照综合坪用价值,湛江圆叶、儋州圆叶、儋州高种、海口圆叶适合作观赏草坪和休憩草坪,湛江圆叶和儋州圆叶适合作运动草坪,湛江圆叶和儋州高种适合作保土草坪。The plant density, uniformity, color, trampling tolerance and coverage were used as indexes to assess the turf quality of eight accessions of Alysicarpus vaginalis germplasm. The weight of the indexes was determined according to different functions of the indexes in the turf, and the assessment scores were used for comprehensive evaluation of the accessions in the turf. The results showed that among the 8 accessions of A. vaginalis the accession Zhangjiang Yuanye （round leaf） was scored highest while the accession Danzhou Jianye （acute leaf） the lowest. According to the overall value of the turf quality the accessions Zhanjiang Yuanye, Danzhou Yuanye, Danzhou Gaozhong （tall）, Haikou Yuanye were suitable for planting in the lawn or turf for aesthetic and recreational purposes, the accessions Zhanjiang Yuanye and Danzhou Yuanye for sport purpose, and the accessions Zhanjiang Yuanye and Danzhou Gaozhong for soil conservation purpose.
