In addition, the methods and process used for calculation of carrying capacity reported in this study should be useful for total quantity control of air pollution emission and system for environmental control assessment. At First, the study used Rollback method to estimate the carrying capacity of five types of air pollution in Tanshui River, and each average carrying capacity of PM10,SO2,NO2,CO and NMHC were 20,711 ton/yr(remaining 28%), 237,248 ton/yr(remaining 85%), 90,693 ton/yr(remaining 53%), 288,277 ton/yr(remaining 57%)and1,575,063 ton/yr(remaining 89%).Then, this study used Genetic programming method in four kinds of meteoric situation to calculate remaining carrying capacity of the air pollutions in Tanshui River. The remaining carrying capacity of the PM10 was 57,863 ton/year in the low temperature and low wind velocity, and 185,741 ton/year in the high temperature and highwind velocity. The remaining carrying capacity of the SO2 was 200,291 ton/year in the low temperature and low wind velocity, and 464,189 ton/year in the high temperature and highwind velocity. The remaining carrying capacity of the NO2 was-7,924 ton/year in the low temperature and low wind velocity, and 120,387 ton/year in the high temperature and highwind velocity. The remaining carrying capacity of the NMHC was 113,360 ton/year in the low temperature and low wind velocity, and 1231,252 ton/year in the high temperature and highwind velocity. Moreover, the least average carrying capacity of PM10, SO2, NO2, and NMHC in the low temperature and low wind velocity. However average carrying capacity of PM10, SO2, NO2, and NMHC have the maximum in the high temperature and high wind velocity. From Rollback method and Genetic programming method, PM10 and NO2 have less carrying capacity, therefore, PM10 and NO2 have the higher priority to be considered as control targeta than NMHC.
