| 摘 要： | 利用西安市及周围四个站点1961-2007年的气象观测资料,运用自回归分析方法,分析了西安市的城市气候特征,并在运用相关系数分析法和主成分分析法的基础上建立了回归模型,考察了地表覆盖变化对城市气候的影响。研究表明：1）西安市城市气候具有暖、干的趋势,一定程度上存在＂热岛＂效应和＂干岛＂效应;2）地表覆盖变化对西安城市气...

| Abstract: | According to the meteorological data in Xi'an and four meteorological stations near by 1961 to 2007,we analyzed the urban climate characters in Xi'an by the regression analysis.Then via establishing regression models on the base of correlation coefficient and principle component analysis,the influence of land cover change on urban climate was inspected.The conclusions were as follow : The climate of Xi'an urban area is becoming warmer and drier,having 'urban heat island effect 'and 'urban dry island effect'... |
