摘　　要：为了探明泉州地区丘陵红壤中金属污染状况,对茶园土壤进行采样,分析Ba、Ca、Al、Fe四种金属含量并进行污染评价。结果表明,泉州地区丘陵红壤可能受到的外源污染物主要来自于含Al、Ba等金属污染源。Fe含量基本呈正态分布,Fe和Al呈显著相关。采用地质累积指数法评价,普通茶园中Al存在污染累积。采用内梅罗综合污染指数法评价,普通茶园中Al、Ba存在污染,生态茶园中仅Al存在污染,前者处于轻度污染以上级别的点位占比高。采用生态风险预警指数法和污染负荷指数法进行评价,普通茶园和生态茶园均属无污染。To investigate the metal pollution status in the hilly red soil of Quanzhou area,soil sampling was carried out in tea gardens,and the content of four metals,Ba,Ca,Al,and Fe,were analyzed,and the pollution level was evaluated.The results indicated that:The possible exogenous pollutants in the hilly red soil in Quanzhou area mainly came from metal pollution sources such as Al and Ba.The content of Fe was basically normal distribution,Al and Fe showed significant correlations.While using the Geoaccumulation index method to evaluate,the pollution accumulation of Al in ordinary tea gardens were happened.While using Nemerow synthetic pollution index method to evaluate,the pollution phenomenon of Al and Ba in ordinary tea gardens were happened,and only Al in ecological tea gardens were happened.The proportion of sampling points with mild pollution of the former was higher.While using the potential ecological risk index method and the environmental risk index method to evaluate,both ordinary tea gardens and ecological tea gardens were pollution-free.
