【摘要】 通过对郑州城市环境气候观测资料分析 ,揭示了郑州市区环境温度的季节分布、不同性质地面环境对温度分布的影响及郑州城市热岛强度的时空变化特点。结果表明 :郑州城市建设规模及其特殊的地面物理性质 ,对气候环境已产生较明显的影响 ,年、季环境温度分布都以市中心温度为高 ,向郊区逐渐降低 ,存在着明显的城市“热岛”现象 ;郑州城市热岛强度的年、季变化与我国北方城市的变化趋势比较一致 ,具有冬强夏弱的特点更多还原

【Abstract】 By analyzing the environmental temperature data of Zhengzhou, the seasonal distribution of the environmental temperature and the effects of different surface environment conditions on the temperature are revealed.The feature of heat island intensity of Zhengzhou varies with time and space is also discussed. The results show that the urban construction scale and the specific surface physical feature of the city have obviously affected the environment temperature distribution in time and space. The urban environmental temperature is higher than that in the suburb. The annual and seasonal variation of heat island intensity of Zhengzhou is coincident with the cities in North China. Heat island intensity in winter is also higher than that in summer.更多还原
