摘　　要：为了研究城市规划对局地气候的影响,以位于天津市滨海新区南部的南港工业区为例,应用区域边界层模式模拟了城市规划前后该区域气候环境要素的变化,同时分析了对该区域石化工业生产的可能影响。结果表明:城市规划对四季温度均有明显的影响,春季主要以降温为主,降幅在13:00最高,可达到0.6℃;城市规划对冬、夏、秋三季温度的影响主要表现为白天降温,而晚间增温,其中冬季气温的变幅高于夏、秋季;城市规划对冬、春、秋三季的水平风速均有明显的增加作用,其中秋、冬两季的风速增加最为明显,最高增加了0.6m.s-1,春季次之,增幅均在0.4m.s-1以上,夏季仅有微弱增加,为0.2m.s-1;气温变化(夜间升高、白天降低)以及风速的提高,有利于该地区石化工业作业生产,增加了夏季作业工人的舒适度,降低了石化工业的风险,同时风速的增加有利于污染物的扩散。总体上,城市规划使该区域气候环境要素发生了明显的改变,有利于石化工业的作业生产。In order to understand the potential effects of urban planning on local climate, the Nangang industrial area in the south Binhai New Area of Tianjin was taken as a case, and a boundary layer model was applied to simulate the variations of climatic environmental elements before and after urban planning, with the possible effects on the petrochemical industry in this area analyzed. The results showed that urban planning had obvious effects on the air temperature in all four seasons. After the planning, the air temperature in spring mostly showed decrease, with the largest decrement of 0.6 ℃ at 1：00 pm, and the air temperature in winter, summer, and autumn showed a pattern of apparent decrease at daytime and the largest increase at night. The variation range of the air temperature was larger in winter than in summer and autumn. Urban planning had obvious effects on the enhancement of wind speed in winter, spring, and autumn, with the amplitude of 0.6 m· s-1 , 0.4 m· s-1 , and 0.6 m · s-1 , respectively. The wind speed in summer after urban planning only had a weak enhancement （0.2 m · s-1 ）. The variation of air temperature and the enhancement of wind speed would benefit the petrochemical industry in this area, because the temperature decrease at daytime, especially in summer, would increase the human comfort and reduce the risks of petrochemical industry, and the enhancement of wind speed would be favorable to the diffusion of pollutants. Overall, urban planning climatic environmental elements have a great change, which would be beneficial to of petrochemical industry. made the local the productionof petrochemical industry.
