Dataset for ozone imacts on NPP in the North China Plain

Ozone pollution led to an average 25% decrease in NPP in the North China Plain (NCP). This decline is consistent with previous estimates that ranged from 10% to 25%. Productivity of forest trees, crops, and grasses declined significantly, ranging from 36.7% to 47.1%. These results have implications for Chinese crops, as lower crop productivity can negatively affect crop yields. Our study highlights the urgent need for action to mitigate the detrimental effects of ozone pollution on ecosystem health and productivity.

臭氧污染导致华北平原（North China Plain, NCP）的净初级生产力（Net Primary Productivity, NPP）平均下降25%。这一降幅与此前10%至25%的估算结果一致。林木、农作物与草本植物的生产力降幅显著，区间为36.7%至47.1%。该研究结果对中国农作物生产具有重要启示：作物生产力降低会对作物产量产生负面影响。本研究强调，亟需采取行动以减缓臭氧污染对生态系统健康与生产力的不利影响。
