摘要
根据重庆市永川区2008年7月～2009年7月的PM10质量浓度资料以及同期的气象资料,对PM10平均质量浓度数据在不同时间和空间上进行了分析,并采用逐步回归方法分季节建立了空气污染物PM10与气象因子的回归模型。模型结果表明,春季PM10预测值与实测值有较大的误差,夏、秋、冬预测值与实测值比较吻合,变化趋势一致。结合该课题得到的结论和PM10产生的根源,提出了PM10污染防治措施。
Based on PM10 data and meteorological data of Yongchuan from July of 2008 to July of 2009,PM10 average concentration date was analyzed in different time and space,and the seasonal stepwise regression model between PM10 concentration and meteorological factors was established.The study results showed that it had a big error between the prediction results and monitoring results of PM10 in spring,while the prediction results corresponded to monitoring results well in summer,fall and winter.The pollution control measurements were put forward to control the PM10 on basis of the source of PM10 and coclusion in this paper.
