Seawater invasion and soil salinization integrated real-time monitoring and evaluating system

Abstract

The invention discloses a seawater invasion and soil salinization integrated real-time monitoring and evaluating system. According to the system, a symmetrical quadrupole sounding method is adopted tomeasure the vertical apparent resistivity of soil at a monitoring point; seawater invasion and soil salinization conditions are monitored according to the relationship between the apparent resistivity and the content of chloride in underground water and the functional relationship between the apparent resistivity and the total salt content in the soil; seawater invasion and soil salinization evaluation are automatically completed according to a measurement result, and an evaluation report is generated. Therefore, the seawater invasion and soil salinization integrated real-time monitoring andevaluation system can simultaneously complete monitoring and evaluation of seawater invasion and soil salinization, greatly reduce the workload, and improve the monitoring efficiency; a laboratory analysis link is omitted, so that a monitoring result can be conveniently and quickly obtained; measurement points are not limited to existing water wells and the like, and therefore, representativenessof the monitoring points and correctness of results are guaranteed.

Description

technical field [0001] The invention relates to the field of environmental monitoring and evaluation, in particular to an integrated real-time monitoring and evaluation system for seawater intrusion and soil salinization. Background technique [0002] Seawater intrusion disasters pollute underground freshwater resources, resulting in deterioration of the ecological environment. People and animals drink poor-quality water, leading to increased disease. Industrial and agricultural production uses polluted groundwater to accelerate the corrosion and aging of industrial pipelines and equipment. In addition, seawater intrusion increases the mineralization of deep soil. High, soluble salts in seawater will also be brought to the soil surface with the use of groundwater, causing salinization of the entire surface, resulting in soil compaction, vegetation decline, and crop yield reduction, and eventually the entire piece of soil degrades, causing damage to coastal areas. production ...

AI Technical Summary

Problems solved by technology

On the one hand, groundwater samples and soil samples at monitoring points need to be collected separately, and most groundwater samples use existing agricultural water wells or residential drinking water wells, which greatly limits the scope of monitoring; Complexity, slow analysis speed, and certain requirements for operators

The evaluation of seawater intrusion and soil salinization requires professional technicians to process and analyze the data according to the relevant evaluation technical regulations after obtaining the monitoring data. The workload is heavy and it takes a long time to obtain the evaluation results.
