2005～2012年山东中南部四大城市大气环境质量状况分析

根据济南、淄博、泰安、济宁4市2005～2012年空气质量日报数据，运用统计分析的方法，对4市空气污染指数（API）月、季节变化特征与年变化趋势、首要污染物及空气质量等级等进行了统计分析对比．研究结果表明：（1）泰安空气质量总体优于淄博、济宁和济南，济南空气质量最差；（2）4城市具有明显相似的APl月、季节变化特征，具体表现为7，8月份APl月均值相对较低，1，2，11，12月份APl月均值相对较高；API季节变化特征为冬季空气质量最差，其次是春季和秋季，夏季空气质量最好，其API季节均值最低；（3）泰安、济宁APl年均值呈上升趋势，说明空气质量在逐渐恶化；济南APl年均值整体下降，空气质量改善；淄博APl年均值呈现倒u型变化，其年际变化最大；（4）4城市首要污染物均为可吸人颗粒，在8年时间序列中所占比例均达78％以上，次要污染物为二氧化硫，主要出现在冬季．

The Spatio-Temporal Comparative Analysis of Coordinated Development Between Urbanization and Eco-Environment in Shandong Province During the Period of Rapid Urbanization

According to the connotation and characteristics of urbanization and ecological environment, the spatio- temporal characteristics of coordinated development between urbanization and eco-environment in Shandong Province during the period of rapid urbanization were analyzed by constructing evaluation index system and using the model of coordinated development degree. The results showed that the coordinated development degree between urbanization and ecological environment experienced three stages i. e. ＂rising antagonistic-undulated developing-steady improving＂. Shandong is at the medium level now with great differences between the east and the west. The highest coordination degree of Weihai City is nearly about 2 times than the lowest Heze City. Not only speeding up the urbanization process but also protecting and governing ecological environment should be concerned in the future. Carrying out differentiated regional policies and taking new road of urbanization can further improve the coordinated development between urbanization and eco-environment, which is helpful in re- alizing the regional sustainable development finally.
