重金属污染对土壤一作物系统的影响研究

近年来，粮食安全问题已得到国家的高度重视，其中重金属污染对粮食安全的影响显得尤为突出，所以针对重金属污染对土壤～作物系统的影响研究也显得更加重要。该文在重金属对作物生长发育、作物吸收累积重金属、重金属在土壤中的运移积累、重金属复合污染和重金属污染修复等方面，对国内外的相关研究进行了一定的归纳总结。

Study of Heavy Metal Pollution Influence to the Soil-Crop System

In recent years, food safety has received national attention, the influence of pollution of heavy metals to commissariat appears highlight particularly, studying the effect appears more important. This article through analysing heavy metals on crop growth and development, crop uptake of heavy metal, heavy metal accumulation in soil, accumulation of compound pollution of heavy metals and heavy metal pollution etc, the relevant research at home and abroad were summarized.
