摘　　要：阐述了氯气的性状、来源和危害。如果氯气逸散于大气中达到一定浓度,不仅直接危害人类健康,而且也伤害农作物,给农作物生产造成巨大损失。对农作物的损伤有急性危害和慢性危害两种。提出了防止或减少氯气对农作物危害的根本措施是加强对污染源的控制,其次是采取绿化措施、农业措施。控制污染源技术措施:吸收法(碱液吸收、二氯化铁吸收、四氯化碳吸收及水吸收)、氧化还原法(铁法)、综合利用法、改进工艺(间接冷却法、用催化剂消除含氯废气)。The characters,sources and harm of chlorine gas are expounded.If chlorine gas escapes in the atmosphere to a certain concentration,it will not only directly harm human health,but also damage crops,causing huge losses to crop production.There are two kinds of acute and chronic hazards to crops.The fundamental measure to prevent or reduce the harm of chlorine to crops is to strengthen the control of pollution sources,followed by greening measures and agricultural measures.Measures to control the source of pollution includes absorption（absorption of alkaline solution,absorption of ferrous chloride,absorption of carbon tetrachloride and water absorption）,oxidation reduction（iron process）,comprehensive use and improved process（indirect cooling method,elimination of chlorine containing waste gas with catalyst）.
