摘要
通过对长春市环境气候观测资料分析 ,揭示了长春市环境温度和降水的季节变化分布 ,不同性质地面环境对温度分布的影响及长春城市热岛强度的时空变化特点。结果表明 :长春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 ;而且长春城市热岛强度的年、季变化与我国北方城市的变化趋势比较一致。
Through observe analysis to Changchun city environmental climate , anno unce Changchuncity area environment temperature and seasonal variation of precip itation is distribute, different natureground environmental impact on temperatur e profile and Changchun urban heat island space-time change characteristic of in tensity. The result shows : The urban construction scale in Changchun and specia l ground physical property, have already exerted a more obvious influence on the climate environment, annual, environment warm to is it regard temperature of ci ty center as high to distribute season, reduce gradually to suburb, the obvious phenomenon of 'heat island' of city exists; And the intensity of urban heat is land of Changchun is annual, the change is more unanimous with the variation ten dency of the northern city of our country in season.
