| Abstract: | Taking Harbin and its surrounding areas as the study area,the air quality index data and the burning point data of straw from 2015 to 2018 were selected.The relationship between the air quality index and the number of burning points in autumn,winter and spring under moderate or above polluted weather conditions was analyzed by using geographic information system spatial analysis method and Pearson correlation system statistical method.The results show that there is a strong positive correlation between the two factors. |
