摘　　要：以水溶性钾为示踪元素 ,解析秋收季节秸秆焚烧对玉溪市大气PM10的贡献。结果表明 ,2 0 0 1年秋收季节 (10月 )水溶性钾浓度 (7 68μg/m3 )比夏季水溶性钾浓度 (2 38μg/m3 )高 3 2倍 ,与 7月至 12月份PM10浓度变化呈显著相关 ,相关系数为 0 810。很显然 。We take water soluble potassium as tracer element, analyze the effect of burning crop stalks to PM10 in Yuxi air environment in harvest season. The results show that the concentration of water soluble potassium (7 68mg/m3) in harvest season (in October) is 3 2 times to that (2 38 mg/m3) in summer. The changes of concentration of PM10 from July to December is significance correlation, the correlation coefficient is 0 810. Obviously, the burning crop stalks in harvest season had bad effect on PM10 of Yuxi air environment.
