【摘要】 健康的土壤是维持人体健康以及国家粮食安全的重要保障。中国部分地区土壤重金属污染较为严重,因此采用合理的预测模型对土壤中的重金属污染状况进行分析和预测,对于土壤的健康管理具有重要意义。聚焦土壤中重金属累积预测模型研究现状,简要分析土壤中重金属的累积行为,阐述不同重金属累积预测模型原理以及实际应用,总结影响预测模型准确度的因素,指出土壤中重金属累积预测模型存在的不足,并对未来发展趋势进行展望。更多还原

【Abstract】 Healthy soil is an important guarantee for maintaining human health and the food safety. Soil heavy metal pollution in some areas is prominent. Therefore, application of an available model to predict the soil heavy metals pollution is of great significance to the soil health management. Focusing on the research status of prediction models for the accumulation of heavy metal in soil, this review firstly given a comprehensive analysis for the accumulation behavior of heavy metal in soil, summarized the principles and application of the prediction model for the accumulation of heavy metal in soil, evaluated the factors affecting the accuracy of the prediction models, pointed out the possible shortcomings of prediction models, and finally forecasted the development of soil heavy metal accumulation prediction models in the future.更多还原
