REGIONAL GRIDDING CUMULATIVE ENVIRONMENTAL RISK EVALUATION SYSTEM AND METHOD BASED ON RISK FIELD

摘要

A regional gridding cumulative environmental risk evaluation system and method based on a risk field, which belong to the fields of environmental sciences and environmental risks. The cumulative environmental risk evaluation system comprises a data collection unit, a data storage unit, an evaluation analysis unit and a risk visualization unit, and can evaluate a cumulative environmental risk and generate a visual environmental risk map via an evaluation result. In the evaluation method, a cumulative environmental risk index evaluation model is built on the basis of a cumulative environmental risk field intensity index, a cumulative environmental risk control mechanism index and a cumulative environmental risk receptor index, and a cumulative environmental risk is evaluated via the built model so as to determine a cumulative environmental risk level of an evaluation region. In conjunction with the cumulative environmental risk evaluation system and evaluation method, a cumulative environmental risk can be scientifically and accurately evaluated, so that strong technical support is provided for management work of the cumulative environmental risk.
