辽宁中部城市群;城市热岛;城市发展指标;影响因子
摘  要：
利用辽宁中部城市群沈阳、鞍山和本溪3个城市气象站及其周围各县气象站1960~2006年年均气温资料,分析了辽宁中部城市群城市热岛效应的年季动态,以及城市热岛与城市发展指标如城市人口数量和绿地面积的关系。结果表明:辽宁中部城市群城市热岛均表现为冬季热岛强度最强、夏季最弱,但沈阳热岛强度秋季最弱。沈阳市和鞍山市城市热岛的年际变化呈增加趋势,增幅分别为0.25℃/10 a和0.16℃/10 a,而本溪市则呈下降趋势,下降幅度为0.44℃/10 a。城市热岛与城市发展指标如城市人口数量和绿地面积的关系是复杂的,只有城市发展指标达到一定的阈值后,才会对城市热岛强度产生影响。

摘  要：
Based on the annual average air temperature data from 1960 to 2006 from weather stations and surrounding weather stations in city groups of middle Liaoning Province including Shenyang,Anshan and Benxi,the annual and seasonal variations of urban heat island effect in city groups of middle Liaoning Province and the correlation between the urban heat island and the urban development indices such as urban population quantity and green area were analyzed.The results indicated that the urban heat island of city groups in middle Liaoning Province all showed the characteristics of the strongest heat island intensity in winter and the weakest heat island intensity in summer.But the heat island intensity in Shenyang was weakest in autumn.The annual changes of urban heat island in Shenyang City and Anshan City showed an increasing trend,with the increasing amplitude of 0.25 ℃/10 a and 0.16 ℃/10 a resp.And that in Benxi City showed a decreasing trend,with the decreasing amplitude of 0.44 ℃/10 a.The correlation between the urban heat island and the urban development indices such as urban population quantity and green area was complex.When the urban development index reached a certain threshold,the urban island intensity would be affected.
