摘要
我国作为农业大国,实际耕地面积正在逐年减少,其原因有城市化建设、公共基础建设占地等,但最主要的是重金属污染。被重金属所污染过的耕地土壤自净能力逐渐降低,实际的农作物产量逐渐减少,且重金属离子会污染农作物根茎,导致最终的粮食作物影响人体健康。基于此,本文对当前耕地土壤的重金属污染情况进行分析,提出更为有效的防控措施,通过采取修复技术提高来保护耕地资源。
As a large agricultural country,the actual cultivated land area is decreasing year by year.The reasons are urbanization construction and public infrastructure construction,but the most important one is heavy metal pollution.The self-purification capacity of cultivated soil contaminated by heavy metals is gradually reduced,the actual crop yield is gradually reduced,and heavy metal ions can contaminate crop roots,leading to the final food crop affecting human health.Based on this,this paper analyzes the current heavy metal pollution of cultivated land,proposes more effective prevention and control measures,and protects cultivated land resources by adopting restoration techniques.
