摘　　要：利用RAMS大气动力模式模拟的气象场驱动中尺度大气扩散模式HYPACT的方法,模拟出TSP的浓度分布及每个污染单元对于地面浓度的分担率,然后根据TSP的国家质量标准,用线性规划的原理与方法计算了兰州市冬季典型日条件下TSP的大气环境容量.计算结果表明,兰州市全年的主要污染物TSP的大气环境容量远小于排放量,削减率达41.99%左右(2000年12月24日),需要削减的排放量很大.Using meso-scale atmospheric dispersion model HYPACT technique drived by meteorologic field simulated with atmospheric kinetic model RAMS, the distribution of TSP concentration and the surface concentration sharing rate for each pollution unit were simulated. Then, using linear programming principle and method, the atmospheric environment capacities of TSP of representative days in Lanzhou City winter were calculated based on the state quality standard. The calculation results show that the year-round atmospheric environment capacity of TSP, the main pollutant in Lanzhou City, is far less than the emission quantity and the cut-rate is about 41.99% on December 24 of 2000. So much discharge amount of TSP is desired to be cut.
