摘要
该文介绍了Ｏ＿３浓度变化对农作物的影响机制，如Ｏ＿３对作物光合与呼吸、生理生化过程和代谢物质、细胞透性、体内各类醇、组织器官以及其它功能的影响，根据美国ＮＣＬＡＮ近１０年的试验资料建立的Ｏ＿３浓度与作物产量的准线性关系，推算和评价了Ｏ＿３浓度变化对我国主要作物产量的可能影响。
A brief introduction of mechanlsrn of the effects of O_3 concentration change oncrops, for instance,the effects of O_3 on photosynthesis and respiration,chemophysiological courses and metabolic material, penetrative features of cells,allkinds of inner enzymes,organs of crops and other functions is given in the paper.Basedon the quasilinear relationship between O_3 concentration and yield of crops by theAmerican NCLAN using the experiment data for nearly ten years the potential effects ofO_3 concentration cliange on yield of main crops in China are studied and evaluated。
