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.
中国快速的经济发展以及对粮食日益增长的需求，已使人们关注到污染水平的臭氧对作物产量的影响。中国已开展了一些关于臭氧对作物产量影响的评估。中国研究人员及国外其他人员已根据地理位置确定了臭氧分布，并据此估算了作物损失。显然，中国地面臭氧水平超过了导致作物损失的临界水平。目前来自臭氧剂量/反应研究的信息有限。鉴于中国幅员辽阔，现有的臭氧监测站点太少，无法提供足够的数据将臭氧分布情况推广至全国范围。关于臭氧对作物损失影响及臭氧分布的数据库存在很大的不确定性。需要开展大量研究，以便准确估算中国臭氧造成的作物损失。
