昌都市土壤重金属镉污染防范治理措施及建议

Prevention and Control Measures and Suggestions for Cadmium Pollution in Soil of Changdu City

  • 摘要: 重金属镉对土壤的污染危害在我国部分地区长期存在,随着含镉农药、化肥的长期施用,生态环境较好的西藏自治区昌都市也开始出现土壤镉污染问题。结合高原地区农业发展实际,以昌都市农业发展中重金属镉污染治理为例,探索昌都市耕地镉污染防治主要措施,如优化调整种植结构和耕作方式、调节土壤pH值、科学施肥及控制污染物源头等,为充分利用有限耕地资源、保障粮食安全和农牧民群众身体健康、改善昌都市农业生态环境提供参考。

     

    Abstract: Pollution hazard of heavy metal cadmium on soil has long existed in some regions of China.With long-term application of cadmium containing pesticides and fertilizers, Changdu City of Xizang Autonomous Region, which has a good ecological environment, has also begun to suffer from soil cadmium pollution.Based on actual development of agriculture in plateau areas, taking treatment of heavy metal cadmium pollution in development of agriculture in Changdu City as an example, main measures for prevention and control of cadmium pollution in farmland in Changdu City were explored, such as optimizing and adjusting planting structure and cultivation methods, adjusting soil pH, scientific fertilization, and controlling pollutant sources, to fully utilizing limited arable land resources, ensuring food security and health of farmers and herdsmen, and improve agricultural ecological environment in Changcheng City.
