Obtained the calculation formulas of stripe—pillar size of two and three dimension in the pillar containing joints by analysing it. Studied the effect of joint trace, angle, density and tension strength on the stability of stipe—pillar. Obtained the upper—limit value of joint angle that has no effect on the stability of stripe—pillar.

为了克服林带声衰减量计算过于简化而引起的公路交通噪声预测精度降低的不足，基于植物内部结构及吸声、散射机理的分析，建立了高速公路林带声衰减量计算公式，公式中包含了林带宽度、密度、平均灌幅、高度和林带近路侧距公路中心线距离等特征参数。

The results showed that coverage, tiller density, turf quality, leaf chlorophyll and water content declined markedly along with turgidity under the persisting stress of heat and drought. Compared with mid-June, turf quality and leaf water content in mid-August had declined about 12.1%-49.8% and 14.2%-27.6%, respectively. Similarly, the activities of SOD and POD in leaves declined 36.5%-55.0% and 46.9%-65.7%, respectively, while the MDA content increased from 19.8% to 88.7%.

结果表明，随着夏季高温伏旱强度的增加和持续时间的延长，各品种的草坪盖度、密度、综合质量、叶片叶绿素含量和组织含水量均持续显著下降，8月中旬的草坪综合质量和叶片组织含水量分别比6月中旬降低了12.1%~27.6%和14.2%~27.6%；8月中旬叶片组织的SOD和POD活性分别比6月中旬下降了36.5%~55.0%和46.9%~65.7%，而MDA含量则增加了
