| 摘 要： | 城市化极大地改变了城市下垫面的性质，这有可能增加灰霾天气发生的概率和强度.利用Landsat-7 ETM+和HJ-1A卫星多光谱遥感数据，通过人工解译获得2002年和2012年武汉市土地利用情况，并对武汉市土地利用规划图进行数字化和尺度转换.在此基础上，针对武汉市典型灰霾天气过程，对不同土地类型（历史、现状和规划）利用WRF-NAQPMS空气质量数值模式进行了不同情景的模拟.同时，对比分析和揭示了不同情境下，大气风场和主要大气污染物浓度场的变化，解析了下垫面对灰霾天气的影响.可为从灰霾天气防治的角度完善城市土地规划和建设提供科学依据.

| Abstract: | Urbanization has greatly changed the nature of the urban underlying surface,which may increase the probability and intensity of haze weather.Using Landsat-7 ETM+and HJ-1A satellite multispectral remote sensing data,land use characteristics in Wuhan in 2002 and 2012 were analyzed by manual interpretation,and the land use planning map of Wuhan city was digitized and scaled.According to the typical gray haze weather process observed in Wuhan,different land types (history,present situation,and future) were simulated using the WRF-NAQPMS air quality numerical model.Simultaneously,the variations of the atmospheric wind field,temperature field,and concentration field of the main atmospheric pollutant in different situations were assessed,and the influence of the cushion on the haze weather was analyzed.The results provide a scientific basis for perfecting urban land planning and construction from the viewpoint of prevention and mitigation of gray haze weather. |
