Agricultural product prohibition area division method and system, electronic equipment and medium

Abstract

The embodiment of the invention provides an agricultural product production forbidding area division method and system, electronic equipment and a medium. The method comprises the steps that n pollutant monitoring values of a target point location of a to-be-divided area are collected; wherein the n pollutant monitoring values comprise n target crop pollutant monitoring values and n soil pollutantmonitoring values which are in one-to-one correspondence; based on the n crop pollutant monitoring values, the to-be-divided area is judged from the human edible part and the livestock and poultry feed part through a comprehensive pollution judgment method, and then the to-be-divided no-farrowing area is obtained by integrating the judgment results of the two parts; based on the n pollutant monitoring values, the complex relationship between the soil and agricultural products of the to-be-delimited prohibited area is comprehensively considered, correlation analysis and enrichment analysis areintroduced, the to-be-delimited prohibited agricultural product prohibited area is comprehensively judged, and the prohibited area division result corresponding to the target agricultural product isobtained, so that the scientificity and accuracy of the division result are improved. Comprehensive and scientific agricultural product prohibition area division is realized, and reference is providedfor subsequent treatment and restoration of cultivated land soil.

Description

technical field [0001] The invention relates to the technical field of agricultural environment, and in particular to a method and system for dividing agricultural product forbidden areas, electronic equipment and media. Background technique [0002] The origin of agricultural products is the source of agricultural product production, which directly affects the quality and safety level of agricultural products, and further affects human health through the food chain. In recent years, with the rapid growth of my country's population and the rapid development of industry, incidents of excessive harmful substances in agricultural products caused by the pollution of agricultural product production areas have occurred from time to time, and the environmental problems of production areas have increasingly attracted the attention and attention of the government and relevant departments. In order to ensure the quality and safety of agricultural products, the Chinese government has p...

Problems solved by technology

However, due to the sparse monitoring points of soil and agricultural products (the density of monitoring points in the research area is often less than 30), when the overall situation of the regional soil environmental quality is unknown, the semivariogram fitting in the kriging interpolation method is the main difficulty. Sparse lower semivariogram fitting error is large

The standard judgment method, such as Hao Ming, etc., based on the "Soil Environmental Quality Standards" and "Limits of Pollutants in Food", based on the heavy metal content of point soil and agricultural products, the key monitoring is divided into 4 types of monitoring units. From a technical point of view, the research area is Suggestions are provided for the division of cut-off areas, but no specific criteria for the division of cut-off areas are given, nor is a set of effective technical methods formed

Based on the principle of division of prohibited production areas of agricultural products, my country has issued normative documents for the division of strict control areas. However, the control area is delineated based on the arithmetic mean value of the single-factor pollution index and the single-factor exceeding rate of target pollutants in the edible parts of specific agricultural products. It is too single and not rigorous enough. When using this standard to delineate the strict control areas of agricultural products, because the complex relationship between soil and agricultural products is not considered comprehensively, the accuracy and sensitivity of the category classification are low, and even all agricultural products have exceeded the standard and are still judged as The phenomenon of non-strictly controlled areas
