摘要
将草坪植被的表观特征(盖度、密度、频度)、色泽(叶绿素含量)、质地(受力作用)5项指标进行定量分级,通过加权平均法所求得分,确定质量标准。
Quality standards were determined through five index grades including apparent characteristics (cover, density, frequency), color (chlorophyl content), texture (resistance to mechanical stress), the grades were calculated with weighted means.
