针对目前绿色农产品规划布局中存在的问题,以元素在岩—土—水—植物系统间的迁移转化规律为出发点,探讨了绿色农产品的安全、品质与地质地球化学背景之间的关系。研究认为:地质地球化学背景不仅影响其安全,而且影响其品质的优劣。在生产布局时,不仅要考虑现时地质地球化学背景,还要考虑外界环境对地球化学背景的影响,对土壤的未来质量进行预警、预测。
In view of the existing problems in the planning and layout of green agricultural products, the relationship between the safety and quality of green agricultural products and the geo-geochemical background was discussed based on the migration and transformation rules of elements in the rock, soil, water and plant systems. The study suggests that: the geo-geochemical background not only affects its safety, but also affect the quality of its pros and cons. In the production layout, not only to consider the current geological and geochemical background, but also consider the external environment on the impact of geochemical background, the future quality of the soil warning and forecast.
