[Method] The upland rice seeds were sowed in pots, in which the soil was previously mixed with a certain amount of Glomus mosseae and 0, 100 and 200 张旭 红 1 ，王 丽 明 1 ，张 莘 2, 林 爱 军 3* （1.北 mg/kg Cu, or 0, 300 and 600 mg/kg Pb. In the control treatment, Glomus mosseae 京 城市学院 ，北京 100083 ； 2.中 国科学院生态 was inactivated before mixed into the soil. Then, the physiological and chemical 环境研究中心城市与区域生态国家重 点实验 properties of the aboveground parts of rice plants were measured at mature stage. 室 ，北 京 100085 ；3.北 京化 工大学 环境 科学 与 [Result] Compared with the control treatment (NM), Glomus mosseae (GM) treat鄄 ment inhibited the POD, CAT and SOD activity while increased the soluble protein 工程系 ，北京 100029） content under 100 mg/kg Cu and 300 mg/kg Pb treatment, improved the POD and
