【摘要】：基于楚雄市城区中心气象站和周围9个加密气象站点及南华2010~2014年气象观测资料,利用Excel制作图表等对楚雄市近年来城市气候变化特征及成因进行了分析与研究,得到楚雄市城市气候变化规律,利用灰色关联分析方法对影响楚雄城市气候的自然和人文因子进行了分析。研究结果表明:近年来热岛强度呈先下降后上升波动趋势,热岛强度最大是在2010年,最小是在2013年,3月份热岛强度最强,8月份最弱。近5年间的降水量波动较大,降水量最多在2014年,最少在2012年,城市雨岛效应比较明显,降雨干湿季分明,城市雨岛强度雨季大于干季。城市相对湿度比郊区少,城市干岛效应明显,楚雄市城市干岛强度雨季大于干季。影响楚雄市城市气候的因子既有人文因子也有自然因子,且人文因子的影响大于自然因子。
[Abstract]:Based on the meteorological observation data from the central meteorological station in the city of Chuxiong City and the surrounding 9 encryption meteorological stations and the Nanhua 2010-2014, the paper analyses and studies the characteristics and causes of the urban climate change in the city of Chuxiong in recent years by using the Excel production chart and the like, and obtains the change law of the urban climate in Chuxiong City. The natural and human factors that affect the urban climate of Chuxiong are analyzed by the gray correlation analysis method. The results show that, in recent years, the strength of the heat island has decreased, the intensity of the heat island is the highest in 2010, and in 2013, the intensity of the heat island is the strongest in March and the weakest in August. The precipitation in the past five years has a large fluctuation and the precipitation is the most in 2014. In 2012, the effect of the urban rain island is obvious, the rainfall and the dry season are clear, and the intensity of the rainy island in the city is greater than the dry season. The relative humidity of the city is less than that of the suburbs, the effect of the dry island of the city is obvious, and the intensity of the dry island in the city of Chuxiong is greater than the dry season. The factors that affect the urban climate in Chuxiong City have both the human factors and the natural factors, and the influence of the human factors is greater than the natural factors.
