Problems solved by technology

Although the sampling analysis method is simple to operate, it consumes time and manpower and is destructive to the sampling site. The modeling method can simplify the research process, but its applicability to specific conditions is poor
TDR is easy to use, high in precision, and fast in measurement. However, due to the limitation of its probe, it can only measure the water and salt content in a certain place, and cannot dynamically monitor the migration of soil water and salt.
3S technology can analyze the distribution of water and salt, but it cannot monitor the dynamic movement of water and salt, and it needs perfect remote sensing data

Embodiment

[0058] Example: Select Dongying seashore as a sample point, first carry out risk exploration and assessment of salinization-prone locations and select sample points, measure the resistivity of the sample point at different salinities, and establish the salinity-resistivity corresponding curve and correlation formula :y=0.565x -1.06 , R 2 =0.952 as Figure 7 shown. According to the geological conditions of the sample point (groundwater buried depth is about 1m), the length of the resistivity measuring device 9 is designed to be 1m. Prepare a circular cylindrical mold with an outer diameter of 50 mm, an inner diameter of 40 mm, and a height of 10 mm, cast nylon to form a nylon module 3, and forge a copper electrode ring 2 with an outer diameter of 51 mm, an inner diameter of 47 mm, and a thickness of 0.5 mm. Select 101 nylon modules 3 to form the probe rod, 100 copper electrode rings 2 are evenly installed between the nylon modules 3, and are sealed with vulcanized rubber. Th...

Abstract

The invention relates to an in-situ, real-time and automatic monitoring system and an in-situ, real-time and automatic monitoring method in the soil water and salt transport process. The system comprises an upper computer, an acquisition and emission device with a general packet radio service (GPRS) module, and a resistivity measurement device consisting of pluggable nylon modules and copper electrode rings among the pluggable nylon modules, wherein each copper electrode ring is connected with a central control unit in the acquisition and emission device through a wire. The method comprises the following steps of: selecting a sample point; measuring the resistivity values of a soil sample at the sample point under different salinity and drawing a salinity-resistivity curve; and receiving a signal from the resistivity measurement device in real time and determining the water and salt transport process according to the preset corresponding curve by using the upper computer. The system has a simple structure, is convenient to use and can be combined according to the specific condition of a monitored place to reduce monitoring cost, a wireless transmission technology is combined, and the acquisition and emission device is remotely controlled by the upper computer, so that the remote, in-situ, real-time and automatic monitoring process is realized, and the system can be widely applied to various soil conditions and is particularly suitable for monitoring the water and salt transport process.

Description

technical field [0001] The invention relates to a system and method for remote in-situ real-time automatic monitoring of soil salinization disasters, in particular to an in-situ real-time automatic monitoring method and system for soil water and salt migration process, belonging to the field of early warning of geological disasters. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with the capillary water, and after the water evaporates, the salt accumulates in the surface soil. Soil salinization will cause the imbalance of soil ecosystem, the degradation of cultivated land resources, and the deterioration of natural ecological environment, which will affect industrial and agricultural production, population quality and social stability. In the salinization research work, the process of soil water-salt migration and the mechanism of water-salt migration are the core issues of resear...
