The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

Sympegma regelii community, a rangeland desert vegetation, has the highest Shannon-Winner species diversity indices (1.706); the communities of Haloxylon ammodendron and Ephedra przewalskii, which have obvious feature of desert vegetation, are in the middle in species diversity indices (0.875-0.890); the communities of Calligonum mongolicum, Populus euphratica, Tamarix ramosissima and Glycyrrhiza inflata, characterized by desert forest of which saline desert bushes and saline meadows are scattered in the communities, have lowest value of the species diversity indices (0.079-0.495). 3 The structure of desert plant community is dominated by the bush layer. The species diversity indices of bush layer (0.769-1.451) is much higher than that of herb layer (0.193-0.254), and the diversity in herb layer is strongly influenced by bush layer. 4 The species diversity of desert plant communities shows a gradient of change with respect to longitude, latitude and elevation. For example, rangeland plant Sympegma regelii, with a high level of diversity indices (1.706), is in transition to desert plants Haloxylon ammodendronn community (with a low level of diversity indices of 1.379) in a longitude gradient and to saline Tamarix ramosessima community (with a low level of diversity indices of 0.376) in a latitude gradient. Calligonum mongolicum community, with a low level of species diversity (0.819), is in transition to Ephedra przewalskii (with a low level of diversity indices of 0.890) and Haloxylon ammondendron community (with the diversity indices of 0.645) in an elevational gradient.

群落Shannon-Wiener物种多样性水平表现为合头草群落最高(1.706)，具有草原化荒漠植被类型的成分；梭梭群落、膜果麻黄群落居中(0.875~0.890)，荒漠植被类型特征明显；沙拐枣群落、胡杨群落、多枝柽柳群落、胀果甘草群落较低(0.079~0.495)，荒漠林、盐地沙生灌丛及盐化草甸植被均有零星分布。3荒漠植物群落结构层次中，灌木层占居主导地位，群落灌木层物种多样性水平(0.769~1.451)远远大于草本层(0.193~0.254)，且草本层物种多样性受灌木层影响较大。4荒漠植物群落物种多样性分布格局表现为经向、纬向和海拔梯度的变化，经向、纬向变化为物种多样性水平较高的草原化植物合头草群落(1.076)向物种多样性水平较低的荒漠植物梭梭群落(1.379)和盐化植物多枝柽柳群落(0.376)的过渡，海拔梯度则呈现低水平的沙拐枣群落(0.819)到高水平的膜果麻黄群落(0.890)向低水平的梭梭群落(0.645)变化。
