中国快速的经济发展和日益增长的粮食需求引起了人们对污染水平臭氧对作物产量的影响的关注。中国对臭氧对作物产量的影响进行了一些评估。中国研究人员和其他国外研究人员已经确定了臭氧在地理位置上的分布，并估计了由此造成的作物损失。很明显，中国的地表臭氧水平超过了农作物损失发生的临界水平。目前来自臭氧剂量/反应研究的信息水平有限。考虑到中国的规模，现有的臭氧监测点太少，无法提供足够的数据来将臭氧分布扩大到全国水平。在臭氧对作物损失的影响和臭氧分布的数据库中有很大的不确定性。需要做大量的研究，才能准确估计中国臭氧造成的作物损失。
Rapid economic development and an increasing demand for food in China have drawn attention to the role of ozone at pollution levels on crop yields. Some assessments of ozone effects on crop yields have been carried out in China. Determination of ozone distribution by geographical location and resulting crop loss estimations have been made by Chinese investigators and others from abroad. It is evident that surface level ozone levels in China exceed critical levels for occurrence of crop losses. Current levels of information from ozone dose/response studies are limited. Given the size of China, existing ozone monitoring sites are too few to provide enough data to scale ozone distribution to a national level. There are large uncertainties in the database for ozone effects on crop loss and for ozone distribution. Considerable research needs to be done to allow accurate estimation of crop losses caused by ozone in China.
