中文摘要：

对如何解决我国土壤污染与农产品安全问题提出了几点意见。首先，应根据土壤污染程度不同采取不同的处置策略，对于中、轻度污染土壤可通过污染物形态的生物可利用性调控原理阻断、降低其生物可利用性，对于严重污染程度的土壤则要采取化学淋洗等方法，同时要注意修复过程中二次污染问题。其次，应加强土壤缓解机理、污染土壤对生物早期伤害的生态毒理学诊断和致毒机理方面研究，并在此基础上系统开展土壤修复基准及土壤生态安全评价体系研究。

英文摘要：

Several guidelines were proposed in this paper regarding the issue of soil contamination and safety of agro-products in China. First, appropriate remediation technologies and management policies should be developed in consideration of the soil contamination level. For soils with low- to middle-level contamination, bioavailability of pollutants can be inhibited or decreased by control or adjustment of the species distribution; for soils with high-level contamination, washing can be applied in remediation, however, re-contamination due to the use of washing agents should be avoided. Furthermore, studies in self-recovery, diagnosis of early damage to biomass, and mechanisms of toxicity of contaminated soils are needed in order to develop a systematic methodology for regulating remediation standards and evaluating the ecological safety of soils.
