Abstract

The invention relates to a regional soil heavy metal pollution index prediction method and device. The regional soil heavy metal pollution index prediction method comprises the following steps: acquiring heavy metal content data of a soil sample; based on the heavy metal content data, determining the sequence of contribution degrees of various heavy metal elements of the soil sample in different pollution states; and predicting the Meiluo comprehensive pollution index in the soil by taking a preset number of heavy metal elements with the contribution degree ranked in the front as input parameters of the support vector regression model. By adopting the method, the appearance conditions of various heavy metal elements in the soil can be obtained through calculation, so that different treatment schemes are formulated according to the contribution degrees of different heavy metal elements; and in addition, the soil heavy metal pollution condition can be predicted through small sample data, so that the influence of data missing or data insufficiency on pollution prediction is effectively avoided.

Description

technical field [0001] The invention relates to the field of environmental pollution prediction, in particular to a method and device for predicting regional soil heavy metal pollution index. Background technique [0002] Heavy metal elements pollute the soil for a long period of time, and the feasibility of repeated sampling to measure the soil heavy metal content and evaluate the soil heavy metal pollution status is very low. Therefore, it is necessary to establish a relevant prediction model to predict the soil heavy metal Nemerow comprehensive pollution index. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a method and device for predicting regional soil heavy metal pollution index. [0004] According to the present invention, a method for predicting regional soil heavy metal pollution index is provided, and the method for predicting regional soil heavy metal pollution index may include: acquiring heavy metal c...
