摘要: 为评估臭氧(O3)污染对山西省冬小麦的相对产量损失、产量损失和直接经济损失,利用2017年冬小麦生长期间山西省各地市O3浓度逐时监测数据,分析O3浓度的时空分布情况,计算冬小麦O3暴露浓度M7指数和暴露剂量AOT40指数,研究O3污染对山西省冬小麦产量的影响。研究结果显示:在冬小麦的生长期(3-5月),山西省O3平均浓度为37 nmol·mol-1,温度上升导致全省O3浓度呈明显上升趋势。山西省M7指数和AOT40指数的空间分布与O3的平均浓度分布情况基本一致,全省M7指数平均值为50 nmol·mol-1,AOT40指数平均值为18 μmol·mol-1。O3污染对山西省冬小麦相对产量损失的影响为7.87%(M7指数法)~24.28%(AOT40指数法),相对产量损失影响最大出现在晋城市。O3污染导致山西省冬小麦产量损失为236 943.07 t (M7指数法)~889 176.97 t (AOT40指数法),带来的直接经济损失为55 918.57万元(M7指数法)~209 845.77万元(AOT40指数法),其中运城市由于产量高导致产量损失和直接经济损失最大。研究表明,O3污染导致山西省冬小麦产量损失较大。为提高冬小麦的产量,需重视大气环境中的O3污染问题。

Abstract: In order to evaluate the relative yield loss rate, yield loss and direct economic loss of winter wheat caused by ozone (O3) pollution in Shanxi Province, the temporal and spatial distribution of O3 concentration was analyzed based on the hourly monitoring data of O3 concentration in each city of Shanxi Province during the growing period (from March to May) of winter wheat in 2017, and then the M7 (O3 exposure concentration) index and AOT40 (O3 exposure dose) index of winter wheat were calculated to study the effect of O3 pollution of ambient air on the yield of winter wheat in Shanxi Province. The average O3 concentration in Shanxi Province was 37 nmol·mol-1 during the growing period of winter wheat (from March to May), and the temperature rise could lead to a significant rise of O3 concentration. The spatial distribution of M7 index and AOT40 index was basically consistent with the average O3 concentration distribution in Shanxi Province. The average value of M7 index was 50 nmol·mol-1, and the average value of AOT40 index was 18 μmol·mol-1. The relative yield loss rate of winter wheat in Shanxi Province caused by O3 pollution was 7.87% (M7 index method) -24.28% (AOT40 index method), and O3 pollution had the greatest effect on the impact of relative yield loss of winter wheat in Jincheng City. The yield loss of winter wheat in Shanxi Province caused by O3 pollution was 236 943.07 t (M7 index method) -889 176.97 t (AOT40 index method). And the direct economic loss was 559.185 7 million yuan (M7 index method) -2 098.457 7 million yuan (AOT40 index method). And as the yield of winter wheat in Yuncheng city is usually higher than that in the other areas of the province, so that the yield loss and direct economic loss of this area are also higher. The results show that O3 pollution could cause a great yield loss of winter wheat in Shanxi Province. It is recommended that more attention should be paid to the yield loss of winter wheat in Shanxi Province caused by O3 pollution, and efforts should be made to alleviate the ambient O3 pollution.

Key words: ozone pollution, Shanxi Province, winter wheat, yield loss, direct economic loss
