An evaluation method for the environmental risk of agricultural product origin

Abstract

The invention discloses an evaluation method for the environmental risk of the production area of ​​agricultural products, which comprises the following steps: Step 1: establishing an evaluation index system for the environmental risk of the production area of ​​agricultural products; (1) consulting data to determine the hierarchical structure of the environmental risk evaluation index system for the production area of ​​agricultural products; (2) ) to conduct primary selection of evaluation indicators, and initially construct an index system framework; (3) use Delphi expert consultation method to screen indicators and establish an evaluation index system framework; (4) adopt analytic hierarchy process to determine the weight of each evaluation index; (5) Determine the classification reference value of each evaluation index, and complete the construction of the environmental risk evaluation index system; Step 2: Apply the comprehensive evaluation method to determine the environmental risk level of the agricultural product origin. The method disclosed in the invention is suitable for environmental risk assessment of different types of agricultural product production areas, and has a complete method system, simple and convenient evaluation process, intuitive evaluation results and good 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
