Determining the appropriate number of civil airports is an important topic in Chinese civil airport planning and development. Qualitative estimation of the number of airports cannot meet the requirement of future planning, thus appropriate quantitative methods are needed for providing sound support for decision making. According to the different accessibility requirements of various demand points, this paper defines different accessibility thresholds for different levels of airports, sets the minimum number of population that an airport should serve, and utilizes the revised Location Set Covering Problem (LSCP) and Maximal Covering Location Problem (MCLP) models for the stratified estimation of the total number and location of Chinese civil airports. The result reveals that to cover 95% of the total population within 100 km rectilinear distance, the required number of airports is 370~385. In the central and western regions, city-and county-level airports are all required. City-level airports need to be constructed in northeast China and there should be a number of new county-level airports in Heilongjiang Province. In the eastern region, seldom any city-level airports but some county-level airports are demanded. The result that some cities do not need new airports in the city-level estimation but the counties under these cities need one or more new airports in the county-level estimation may seem counter intuitive, but this research found that this result is reasonable. The result is heuristic for future civil airport planning.
