Abstract

The invention discloses a regional gridding cumulative environmental risk assessment system and method based on a risk field, and belongs to the field of environmental science and environmental risks.The cumulative environmental risk assessment system comprises a data acquisition unit, a data storage unit, an assessment analysis unit and a risk visualization unit, and can assess cumulative environmental risks and generate a visual environmental risk map according to assessment results. According to the evaluation method, an accumulative environmental risk index evaluation model is establishedbased on an accumulative environmental risk field intensity index, an accumulative environmental risk control mechanism index and an accumulative environmental risk receptor index, accumulative environmental risks are evaluated through the established model, and the accumulative environmental risk level of an evaluation area is determined. In combination with the cumulative environmental risk assessment system and assessment method, the cumulative environmental risk can be scientifically and accurately assessed, so that a powerful technical support is provided for the management work of the cumulative environmental risk.

Description

technical field [0001] The invention belongs to the field of environmental science and environmental risk, and specifically relates to a regional gridded cumulative environmental risk assessment system and method based on a risk field. Background technique [0002] Taking regions as units, carrying out environmental risk assessments and drawing gridded environmental risk maps can support my country's environmental risk priority identification, classification, and zoning management. [0003] Environmental risks include sudden environmental risks and cumulative environmental risks. For regional grid-based sudden environmental risk assessments, my country has issued the "Recommended Method for Risk Assessment of Environmental Sudden Environmental Events in Administrative Regions" as a regional emergency assessment method based on risk fields. Technical basis for environmental risk assessment. In terms of cumulative environmental risk, the existing assessment methods are mainly ...
