摘 要：
基于卫星遥感数据及统计数据实现城郊分类的方法,利用赤壁、通城的1960~2014年及1979~2014年两个时段气温观测数据(OBS)以及美国国家环境预测中心(NCEP)和大气研究中心(NCAR)1979~2014年NCEP/NCAR再分析资料,采用UMR方法(Urban Minus Rural)和OMR方法(Observation Minus Reanalysis)计算了城市化对咸宁地区温度变化的影响。研究结果表明:1979~2014年与1960~2014年相比,咸宁地区城郊站气温观测数据(OBS)中呈显著增温趋势的是春、夏、秋及年的平均最低气温、平均最高气温、平均气温观测数据,城郊站冬季平均气温、平均最高气温增温趋势变小,UMR方法计算城市化对冬季平均最高气温贡献率从26%上升至55%。本文应用UMR方法与OMR方法计算的春、秋、年平均气温城市化贡献率基本一致,特别是冬季平均气温(OMR方法)、冬季平均最高气温(UMR方法)增暖影响均非常明显,但UMR方法表明城市化进程对夏季气温增暖影响在逐渐减弱,OMR方法下城市化对夏季平均气温增暖为负值。

摘 要：
In this study,the suburban classification was achieved by the satellite remote sensing data and statistical data. According to the air temperature observation data( OBS) of Chibi station( as urban station) and Tongcheng station( as suburb station) during 1960 ~ 2014,and the reanalysis data( R1) of NCEP and NCAR during 1979 ~ 2014,we used UMR( Urban Minus Rural) method and OMR( Observation Minus Reanalysis) method to calculate the contribution of urbanization to the air temperature variability in Xianning area. The results showed that: through the comparison of OBS during 1979 ~ 2014 with OBS during1960 ~ 2014,the average minimum air temperature,average maximum air temperature and average air temperature in spring,summer,autumn and whole year in OBS revealed a significant increasing trend; while the increasing trend of the average air temperature and average maximum air temperature in winter was little in Xianning area. The contribution rate of urbanization to the average maximum air temperature in winter increased from 26% during 1960 ~ 2014 to 55% during 1979 ~ 2014 through UMR method. The contribution rates of urbanization to the average air temperature in spring,autumn and whole year calculated by UMR method and OMR method were basically the same. The urbanization had a very significant effect on the average air temperature in wither( OMR method) and the average maximum air temperature in winter( UMR method),but it had a weak( UMR method) or negative( OMR method) effect on the average air temperature in summer.
