摘　　要： 为了建立适用于农村的土壤重金属污染监测与评价方法,以广东省典型农村耕地土壤监例,通过对比总体评价与分类型评价的不同结果,提出分类型开展农村土壤重金属监测的方法和性。结果表明,在工业型、种植型、生态型和其他型4类试点农村中,工业型农村土壤受污染程度最重。不同类型农村土壤特征污染物不同,种植型农村土壤以镉超标为主,工业型和其他型以砷为主。分类型开展农村土壤重金属监测与评价,能有效评估农村土壤污染特征,是深入进行污染分析的基础。 In order to establish the applicable method to monitor and evaluate the rural soil heavy metal pollution, the method and its importance of distinguishing the rural type were proposed, which were based on the study of typical rural cultivated land in Guangdong through comparing the difl!erence between the overall evaluation and the classified evaluation. The results showed that： in 4 types of pilot villages, the soil in industrial village was polluted the most heavily. Different type of villages had the different particular soil heavy metal pollutants, the soil in planting-village was polluted by Cd more frequently, the soil in industrial village and the other type village was polluted by as more frequently. By means of this method, the particular pollutants in different type of rural soil could be revealed easily. It＇s helpful to analyze the pollution source.
