摘要
利用楚雄市 1997年、 2 0 0 2年道路交通噪声的例行监测资料进行了多元对数线性回归分析 ,用建立的对数线性模型对 1996~ 2 0 0 2年各类车流量平均值预测等效声级 ,并与实际值比较 ,结果表明 :全城测点在作重大调整后 ,必须重新建立模型。运用 2 0 0 2年监测数据进行了聚类分析 ,以期找到几类测点特性 。
A multivariate logarithm regression analysis is made with the regular monitoring data of traffic noise in 1997 and 2002 in Chuxiong city, and the established logarithm linear model is used to predict the equivalent sound level of average vehicle flux during 1996 to 2002. Compared to actual sound level, the predicted level for 1996-2000 is ok, but not ok for 2001 and 2002, due to the great change in acoustic environment. A cluster analysis is done for monitoring data in 2002 to try to find the features of testing points and hence to provide reference for acoustic environmental planning.
