| 摘 要： | 针对山西省阳泉市平定近年日照时数异常减少的情况,利用阳泉市3个地面气象站资料,从影响日照时数的气象因素和社会发展因素出发,比较分析了阳泉市各地城市化发展对日照时数影响的差别,找出平定日照时数异常减少的原因。结果表明:在霾日数、总云量、降水量、相对湿度等相关的气象要素中,平定日照时数的变化与霾日数相关性最强;平定、阳泉日照时数与霾日数显著负相关,日照时数的大幅减少与霾日数的大幅增加相伴;平定、阳泉主要城市发展因子与霾日数显著正相关,与日照时数显著负相关,城市化发展使平定、阳泉大气污染物增加、霾日数增加、大气透明度下降、日照时数减少。城市化发展对日照时数的影响与城市化发展速度及地理地形形成的大气污染扩散条件有关。平定城市化急剧发展与山间盆地地形的共同因素导致平定日照时数异常减少。

| Abstract: | In the case of sunshine hours of Pingding of Shanxi Province decreased abnormaly in recent years, the data of 3 meteorological observation was used to analyze the differences of influence of urbanization development on sunshine hours in Yangquan from the meteorological factors and social development factors affecting sunshine hours. The reasons for decrease abnormaly of sunshine hours in Pingding was found out. The results showed that sunshine hours was correlated best with haze days among related meteorological elements such as haze days, total cloud cover, precipitation and relative humidity in Pingding. Sunshine hours significantly negative correlated with haze days and reduced greatly accompanied with a increase of haze days by a big margin in Pingding and Yangquan. The major urban development factors significantly positive correlated with haze days and negative with sunshine hours in Yangquan and Pingding. Urbanization development could increase the atmospheric pollutants, increase haze days, decrease atmospheric transparency and reduce sunshine hours in Yangquan and Pingding. Urbanization development impact on sunshine hours related to the atmospheric pollution diffusion conditions formed by geography and topography. Sunshine hours decreased abnormaly in Pingding was caused by rapid development urbanization and the intermountain basin terrain. |
