摘　　要：乐安河流域的历史遗留污染与近年来开发活动的排放给当地土壤环境带来相当大的压力,但该区域的土壤空间风险分布底数并不清楚。以乐安河为例,结合区域人群活动特征、污染物空间分布与风险,建立了土壤环境空间健康风险评估技术。研究发现,该区域的历史矿渣堆存区为高风险区,且镉为主要风险源。因此,建议将这些区域列为禁止开发区,并作为优先生态修复区。研究探索建立的空间尺度的健康风险评估技术,有望为土壤生态空间划分与综合整治提供依据。Historicalpollution and emission resulted from economic development demands has lead to serious soil environment in Le'an River basin.The situation is laden by unclear baseline data of soil risk spatial distributions.This research combines the characteristics of regional population activities,spatial distribution of pollutants and risks,and establishes a soil environmental spatial health risk assessment technology.The results reveal that some historical slag storage areas are proved the high-risk areas,and cadmium containment is the prior risk.Accordingly,these areas should be assigned as the prohibited zone and the prior ecological restoration areas.The spatial scale health risk assessment technology presented in this study is expected to provide a basis for the division and comprehensive management of soil ecological space.
