灌区水生态环境风险评估研究进展

Research progress on risk assessment of water ecological environment in irrigation districts

系统梳理了灌区水生态环境污染物来源及类型、污染物迁移转化过程和风险评价方法,从地表水生态环境风险评估、地下水生态环境风险评估、土壤生态环境风险评估和人体健康风险评估4个方面,系统总结了灌区水生态环境风险评估的研究进展,提出今后应加强灌区水生态环境污染治理及相关管理制度研究、加大灌区水生态环境风险评估机理研究、加强灌区水生态环境和农产品质量安全风险预警技术研究以及加强生态灌区建设与评估。

The sources,types,migration and transformation process and risk assessment methods of water ecological environmental pollutants in irrigation districts were systematically reviewed.This paper systematically summarized the research progress of water ecological environment risk assessment in the irrigation districts from four aspects,such as the surface water ecological environment risk assessment,groundwater ecological environment risk assessment,soil ecological environment risk assessment and human health risk assessment.In the future,it is necessary to strengthen the research on the pollution control of water ecological environment and related management system,increase the research on the risk assessment mechanism of water ecological environment,strengthen the research on the risk early warning technology of water ecological environment and agricultural product quality and safety,and strengthen the construction and assessment of ecological irrigation districts.
