Abstract: It is of important practical significance for effectively assessing the functions of atmospheric ecological services and strengthening the construction of ecological environment to study the inversion of atmospheric water vapor and understand its spatiotemporal change. Based on the CE-318 observed atmospheric vapor data,sounding data and surface vapor pressure data,the traditional regression model,CE-318-based atmospheric water vapor inversion model and seasonal model were constructed by traditional regression analysis and improved regression analysis. The optimal inversion model of atmospheric vapor over the study area was selected by the accuracy evaluation analysis. The main conclusions are as follows: The inversion results of the three models constructed were all relatively satisfactory,and the inversion results of the atmospheric water vapor inversion model based on CE-318 were the most accurate. Its item inspection indexes were the best values in the accuracy tests of the three models,and the atmospheric water vapor inversion models were optimal for the study area.
