摘　　要：通过选取兰州中川机场2008—2010年的地面气象观测资料，利用箱模型，在A值法的基础上，加入了环境变动量，对规划中的兰州新区大气环境容量的年际变化、年变化、日变化等进行了分析。该模型在计算大气环境容量时体现了污染因子在大气环境中的迁移转化规律，能够反映污染物在大气环境中的动态变化过程。结果得到兰州新区SO2全年大气环境容量为15．03×10^4t，PM10为18．03×10^4t，NO2为15．16×10^4t。基本揭示了该地区大气环境容量的特征，将对新区规划建设及污染物排放限额制定起到了一定的指导作用。The atmospheric environmental capacity refers to the atmospheric environment pollution of a kind of pol- lutants. Simply speaking, it refers to a pollutant carrying capacity which a regional environment can accept. Envi- ronmental capacity is the basis to confirm the index of the pollutant discharge capacity. It will ensure the realization of environmental protection which means that the discharging capacity is smaller than environmental capacity. The Lanzhou New District of 806 km2 area will be located in the Qinwangchuan basin between Gaolan County and Yong- deng County. It is one of major projects which are supported by the State Council of China, the provincial party committee and the government of Gansu Province. The study and the checking of the atmospheric environmental ca- pacity are the precondition and base of atmospheric pollution total amount control. The accurate calculation of at- mospheric environmental capacity can provide scientific basis for the regional atmospheric pollution control and en- vironmental planning. At the same time, the limited resources entificity and systematization of the environmental management. can also be fully utilized, and then promote the sci- After summarizing and analyzing some domestic and overseas studies on the atmospheric environmental capacity calculating methods, A-value method, which is the sim- plest mode, is adopted in this paper to account the atmospheric environmental capacity in Lanzhou. The SO2, PM10 and NO2 are selected as the influence factors. By using the observation data in Zhongchuan airport station from 2008 to 2010, A-value method was adopted to count the atmospheric environmental capacity in Lanzhou New Dis- trict. In the process of calculating the atmospheric environmental capacity, the transportation and diffusion, dry deposition, wet deposition and chemical transformation courses were considered in this thesis. Thus the model can reflect the transference and transformation of atmospheric environmental pollutants, and the dynamic changing proces
