Abstract

The invention discloses a test method and system of suitability of soil heavy metal of an agricultural regional plot of land, belonging to the technical field of soil test. The method comprises the following steps of: S1, according to a random sampling way, selecting preset number of sampling nodes, obtaining the multivariate data of each sampling node, and recording the coordinate data of all sampling nodes; S2, respectively carrying out data processing for data of each attribute in the multivariate data to eliminate abnormal data; S3, respectively interpolating and fitting the data of each attribute to obtain a multi-index evaluation data set for representing an range of an agricultural regional plot of land to be tested; S4, and determining the soil pollution degree of the range of the agricultural regional plot of land to be tested according to the multi-index evaluation data set. The invention provides a data processing flow method relative to improving the reasonable test for soil heavy metal of the regional plot of land. The data quality can be effectively ensured, meanwhile the data processing accuracy is increased, and therefore the test accuracy of the heavy metal soil of the agricultural regional plot of land is increased.

Description

technical field [0001] The invention relates to the technical field of soil testing, in particular to a method and system for testing the suitability of soil heavy metals in an agricultural area plot. Background technique [0002] my country's agricultural production environment has changed with the transformation of farming models, the adjustment of rural industrial structure and the continuous increase in the amount of fertilizer used in agricultural production. The environmental pollution of agricultural products is getting worse day by day, especially heavy metal pollution has affected the output and quality of agricultural products, and will have unpredictable and serious impact on people's life and health. Therefore, it is more important to monitor the pollution of the environment of agricultural products, especially the pollution of heavy metals in the soil and test the suitability of the soil. [0003] At present, foreign countries and my country have not yet formul...
