Agricultural product origin environment risk evaluation method

Abstract

The invention discloses an agricultural product origin environment risk evaluation method. The method comprises the following steps: step 1, establishing an agricultural product origin environment risk evaluation index system; (1) consulting data and determining a hierarchical structure of an agricultural product origin environment risk evaluation index system; (2) carrying out primary selection of evaluation indexes, and preliminarily constructing an index system framework; (3) screening the indexes by adopting a Delphi expert consultation method, and determining an evaluation index system framework; (4) determining the weight of each evaluation index by adopting an analytic hierarchy process; (5) determining a classification reference value of each evaluation index, and completing the construction of an environmental risk evaluation index system; and 2, determining the risk grade of the agricultural product origin environment by applying a comprehensive evaluation method. The methoddisclosed by the invention is suitable for environmental risk evaluation of different types of agricultural product production places, and the method is complete in system, simple and convenient in evaluation process, visual in evaluation result and good in applicability.

Description

technical field [0001] The invention relates to an evaluation method for the environmental risk of agricultural product origin. Background technique [0002] The current soil environment is generally not optimistic. Some areas have serious soil pollution, and the quality of cultivated land soil environment is worrying. In addition, although the quality of the air environment has improved in recent years, there are still several times of severe pollution every year. At the same time, some rivers have exceeded the standard, resulting in varying degrees of pollution to the soil irrigated with sewage. The total discharge of waste gas and wastewater pollutants remains high, solid waste management is not standardized, soil pollution is serious in some areas, and there is even a trend of aggravating pollution. The risk of soil environment has increased, posing a serious threat to the quality and safety of agricultural products and human health. [0003] At present, there are no r...

[0002] The current soil environment is generally not optimistic, the soil pollution in some areas is serious, and the soil environment quality of cultivated land is worrying

In addition, although the quality of the atmospheric environment has improved in recent years, there are still several severe polluted weather every year.

At the same time, some rivers have exceeded the standard, resulting in varying degrees of pollution to the soil irrigated with sewage

The total discharge of waste gas and wastewater pollutants remains high, the management of solid waste is not standardized, and soil pollution in some areas is serious, and there is even a trend of aggravating pollution. The risk of soil environment has increased, posing a serious threat to the quality and safety of agricultural products and human health.

[0003] At present, there is no report on the environmental risk assessment indicators and assessment methods of agricultural product origin, and there is no disclosure of objective, effective and comprehensive assessment indicators and assessment methods in the implementation of environmental risk management and control
