【摘要】 贵州瓮福磷肥厂厂区因氟化氢(HF)污染,草坪成坪后3个月内就出现氟化氢污染伤害症状。在比较试验后发现,草坪草对氟污染的反应不同,用草坪植被指数作属性进行聚类分析,将15种试验草坪草划分成了不敏感,较不敏感和敏感3个反应类型,以草坪草叶片含硫量和草坪植被指数作属性进一步聚类,划分出了强抗性,中抗性和弱抗性3个抗性类型。更多还原

【Abstract】 The turf in Wengfu Phosphate Fertilizer Factory in Guizhou shown the damaged symptoms after establishment for 3 months because of hydrogen fluoride(HF) pollution,and it was found that the response of tested turfgrasses to the pollution was different.By using the attribute clustering analysis through turf vegetation index,15 tested turfgrasses could be divided into 3 groups(non-sensitive,medium sensitive and sensitive),and then,by using the sulphur content in leaf and turf vegetation index as grouping factors,the tested turf grasses were further divided into 3 groups(strong tolerance,medium tolerance and weak tolerance)更多还原
