我国农田土壤重金属污染及其防治策略研究进展

Research Progress of Heavy Metal Pollution in Farmland Soil and Its Prevention and Control Strategies in China

长期的工业化发展,造成土壤中的重金属不断积累,土壤生态环境不断恶化,给农业生产和生态环境造成极大的破坏。由于重金属元素不能够被降解,当被农作物吸收后,会沿着食物链进入人畜体内并产生毒害作用,已经成为当前非常重视的环境问题。提出土壤重金属污染程度对农作物生长的影响分析研究,通过实验验证不同土壤重金属污染程度对农作物生长各个阶段的影响,依据分析结果,制定科学的、有效的土壤重金属污染治理方案。

Long-term industrialization has resulted in the continuous accumulation of heavy metals in the soil and the continuous deterioration of the soil ecological environment,causing great damage to agricultural production and the ecological environment.Since heavy metal elements cannot be degraded,when they are absorbed by crops,they will enter humans and animals along the food chain and produce toxic effects,which has become an environmental issue that is currently very important.This article analyzes the impact of soil heavy metal pollution on crop growth,verifies the impact of different soil heavy metal pollution on the growth of crops in various growth stages through experiments,and formulates a scientific and effective soil heavy metal pollution control plan based on the analysis results.
