中文摘要	结合GIS空间化技术，对中国近50年平均气温数据进行定量化的分析，并分析其时空演变规律。采用空间化气候值十年际距平空间插值法生成中国1951-2001年分辨率为10km*10km的年、季平均气温空间化数据，通过对近50年空间化数据的分析，认为近50年中，年、季的全国平均气温都表现出显著增温趋势，冬季增幅最大，为0．313℃／10a，夏季增幅最小，为0．152℃／10a，年平均气温增幅为0．208℃／10a。1980年代中期以后增温趋势更加明显。从空间分布看，我国西南地区及西藏东南部和新疆西天山中段在不同季节都是主要的降温区域：而北方大部和西藏中西部地区在不同季节都表现为较强的增温趋势，我国东南地区在不同季节温度变化并不稳定，增温或降温的幅度都很小。暖冬事件在北方发生比较频繁，四川及云南部分地区较少，全国发生面积呈逐渐增大的趋势，增幅为国土面积的8．6％／10a。冷夏在新疆南部、西藏西北部和东南部以及江淮一带发生次数较多，辽宁南部、新疆沙漠地区、西藏中部、青海东部、四川太部分地区以及长江以南广大地区最少。全国发生冷夏的面积不断减小，50年平均减幅约为国土面积的5．8％／10a。
英文摘要	Spatialization technique is used to quantificationally analyze the mean surface air temperature data in China in recent 50 years. Spatial-temporal evolvement rules of climatic factors are accurately found out. The spatializated climatic value integrating with the multi-annual deviation from normal interpolation methods is used to build annual and seasonal spatializated datum in China from 1951 to 2001 with a resolution of 10 km*10 km. By the analyzing, the conclusions are as follows： Firstly, the annual and seasonal mean air temperature indicate an increasing trends in China during 50 years, with a maximum rising of 0. 313℃/10a and a minimum rising of 0. 152℃/10a in winter and summer, respectively, besides an annual rising of 0. 208℃/10a. It is much more evident for increasing trends after middle of 1980＇s. Secondly, as far as space scale is concerned, the areas of decreasing temperature in every season include Southwest China, Southeast Tibet and the West of Tian mountain. On the contrary, the most area of North China and midwest of Tibet indicate a strong increasing trends. At the same time, in Southeast China, mean air temperature does not indicate evident change trends. Thirdly, the warm winter events happen frequently in North China and infrequently in partial area of Sichuan and Yunnan provinces. Besides, the area of happening warm winter is constantly expanding, with a rising range of country area of 8.6%/10a in the past 50 years. Additional, the south of Xinjiang province, the northwest and southeast of Tibet and the areas between Changjiang River and Huaihe River are the area where cold summer happen frequently. Furthermore, the south of Liaoning province, the desert area of Xinjiang province, the central Tibet, the most area of Sichuan province and the south of Changjiang River are the area where cold summer happen infrequently. The area happening cold summer is constantly decreasing, with a decreasing range of country area of 5.8%/10a in the past 50 years.
