中文摘要	本文利用2006年2月17日3月2日在南京市区和郊区测得的辐射、湍流通量和脉动风速资料，定量分析了城、郊不同下垫面辐射收支、热量平衡特征及各分量的变化，结果表明：（1）不同天气条件下辐射平衡特征城、郊有一定差异，在晴天时差异最大，在下雪天时差异最小，但多云时更接近各辐射分量城、郊差异的平均特征；（2）城、郊下垫面感热和潜热分布不均，尤其是潜热城、郊对比有较大差异；（3）观测期间平均波文比（Qh／Qe）市区为7．8，与荒漠干旱地区接近，郊区为1．8。
英文摘要	The radiation, turbulence flux, fluctuation wind velocity data observed using the eddy correlation method on the urban and suburban sites in Nanjing from 17 February to 2 March 2006 are used in this paper to analyze the characteristics of the radiation and heat budget over different urban and suburban underlying surfaces, and the changes of each component, as well as the differences of urban and suburban. The results show：（1） the diurnal variation patterns of various radiation components accorded with the generally observed patterns, the urban and suburban difference of net short and long wave radiation, and net radiation varied with different weather conditions, with a largest difference in sun-shining days, a least difference in snowing days, and a medium, representative difference in cloudy days. Among various radiation components, the net short wave radiation dominated the ground surface radiation budget. （2） Characteristics of the heat budget change over the different urban and suburban underlying surfaces were significantly different. The Bowen ratio （Qh/Qe） in the observation period was 7. 8 （about equivalent to that in desert/arid areas） in the urban area, but only 1.8 in the suburban area. （3） The surface net radiation, sensible heat and latent heat fluxes over the urban and suburban areas showed large differences, in fact, the latent heat fluxes showed the largest difference.
