Decision-making system and method for heavy metal pollution of farmland soil

Abstract

The invention provides a decision-making system and method for heavy metal pollution of farmland soil. The method is based on monitoring data of heavy metal pollution of farmland soil in a monitoringarea, constructs a farmland soil heavy metal pollution risk comprehensive assessment index system, a graded early warning model, an emergency disposal model and a crop planting adjustment model to assess the risk of heavy metal pollution in the farmland soil and quickly make an emergency response, and at the same time, can also adjust the planting structure of crops in a heavily polluted area. Thesystem includes data collection, data management, risk assessment, graded early warning, emergency disposal, planting adjustment and information visualization modules which are used for monitoring, assessing and responding quickly to heavy metal pollution in the farmland soil. The decision-making system and method for the heavy metal pollution in the farmland soil according to the invention can significantly improve the automation and intelligence levels of management decision making of the heavy metal pollution in the farmland soil.

Description

technical field [0001] The present invention relates to farmland heavy metal pollution prevention and control technology, more specifically, relates to a kind of farmland soil heavy metal pollution decision-making system and method. Background technique [0002] Heavy metal pollution is the environmental impact caused by heavy metals or their compounds, mainly caused by human factors such as mining, waste gas discharge, sewage irrigation and excessive use of heavy metals. [0003] Soil is the carrier of crop growth, and farmland soil safety is closely related to the quality and safety of agricultural products. Heavy metal pollution in farmland soil has become an important factor leading to the quality and safety of agricultural products. In 2016, the State Council issued the "Action Plan for Soil Pollution Control" (referred to as "Soil Ten"). Pollution census, prevention or monitoring work, the relevant census or monitoring data is growing exponentially. [0004] However,...
