摘　　要：在参阅国内外有关环境累积效应文献的基础上,总结和提出了金属矿集区地球化学环境累积效应的概念、影响因素、类型和工作方法。将矿集区地球化学环境累积效应划分为时间拥挤、空间拥挤等8种类型,识别土壤环境重金属累积效应背景值的方法有对比法和地球化学基线法,累积效应的研究内容包括累积因子、累积速率等8个方面。研究成果对于开展矿山地质化学环境累积效应具有借鉴和指导意义。In this study, the concept of geochemical environmental cumulative effects of soil heavy metal pollution in the ore concentration area is proposed, and the influencing factors, types and research methods are systematically summarized based on consulting numerous papers concerning the cumulative environmental effect published both in China and abroad. The definition includes overall effects of comprehensive reactions between heavy metal elements which are harmful to the environment and the transference and precipitation of these elements in the special environment before, during and after mining . The influencing factors of cumulative effects are composed of premining ore scale, ore-bearing rock, ore texture and structure, geographical environment, hydrological conditions, weathering conditions and mining methods and techniques. The types of cumulative effects are classified into eight types, such as time-crowded and space crowded effects. The results obtained by the authors have a great reference and guiding significance for the study of geochemical environmental cumulative effect.
