| 摘 要： | 选用咸宁市金沙区域2006年6月至2007年5月可吸入颗粒物质量浓度监测资料，分析了金沙颗粒物质量浓度时间分布特征。分析结果表明：金沙三种可吸入颗粒物PM10、PM2.5、PM1.0质量浓度变化规律基本一致，年季变化表现为秋冬大，夏春小；日变化呈双峰双谷型周期性变化，白天大于夜间，最大值出现在下午16-19时，最小值出现在清晨03-07时，除秋季外第二峰谷表现不明显。且雨雾天气PM10浓度较晴到多云低。且通过与2006年6月至2007年5月的地面气象要素资料相关分析，发现PM10质量浓度与气温、气压呈显著正相关，与降水、风速、湿度呈显著负相关。

| Abstract: | The temporal distribution characteristics of PM mass concentrations are analyzed by using the monitoring data from June 2006 to May 2007 in Jinsha region in Xianning.The results show that the variation features of mass concentrations of PM10,PM2.5 and PM1.0 are in agreement,the seasonal variable characteristic is that the concentrations in autumn and winter are larger than those in summer and spring;the diurnal change is periodic change with two peaks and two valleys,the concentrations in day are larger tha... |
