[0002] Soil pollution refers to the entry of certain substances into the soil due to human factors. The substances can be inorganic or organic. When a substance causes the soil to be contaminated by inorganic pollutants or organic pollutants, the properties of the soil itself will change. When the soil is polluted, it will affect the effective utilization of the soil. When the soil is polluted, it will even endanger public health and damage the ecological environment.

[0003] Inorganic pollutants mainly include acids, alkalis, salts (such as perchlorates) and heavy metals (such as copper, mercury, chromium, cadmium, nickel and lead), etc. Organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum and synthetic detergents, etc. These pollutants will seriously endanger public health and damage the ecological environment after entering the soil.

[0004] Currently, there are two types of soil pollution remediation technology: physical remediation technology: reducing the content of heavy metals in the soil by removing contaminated soil or mixing contaminated soil with uncontaminated soil; chemical remediation technology: adding chemical substances (such as lime, phosphates and biochar) to the soil to cause chemical reactions between heavy metals and chemical substances to form insoluble compounds, thereby reducing the soil's absorption of heavy metals; and biological remediation technology: utilizing the heavy metal accumulation characteristics of certain plants (such as landscape trees) to absorb the heavy metals in the soil and accumulate them in the plants, and then removing the heavy metals by harvesting the plants.

The number of cloth points in each cloth-point area may be the same or different. If the number of cloth points is the same, the areas of all the cloth-point areas are the same. If the number of cloth points is different, the areas of all the cloth-point areas are different, and the areas of all the cloth-point areas are determined according to the situation.

[0084] Example 4;

[0085] Based on Embodiment 2 and Embodiment 3, in step B), the vector depth method is as formula (3) below:

[0086] (3);

[0087] Wherein, is the depth at which the soil can be collected, is the set depth at which the soil can be collected; is that the set soil collection direction is first from the ground towards the underground direction and then from the underground towards the ground direction; represents the operation combining the depth at which the soil can be collected with the soil collection direction; is that data collection is performed on the soil under the condition of combining the depth at which the soil can be collected with the soil collection direction;

The detection module emits ultrasonic waves, and the ultrasonic waves pass through the point. The path of the ultrasonic waves is perpendicular to the ground. The ultrasonic waves detect the soil below the point. After the ultrasonic waves reach a certain depth below the point, the ultrasonic waves return along the original path to the point and the detection module. In this way, the depth at which the soil can be collected can be determined, and the soil collection direction is that the ultrasonic waves first go from the ground towards the underground and then from the underground towards the ground for collection. In this way, the regional sampling soil collection model below the point is constructed , the regional sampling soil collection model below the includes the soil data below the point. Similarly, the regional sampling models for the soil below each sampling point are all constructed by formula (3). Therefore, each regional sampling model for the soil includes the collection of the soil data below each respective sampling point.

[0091] Example 5;

[0092] Based on Examples 2 to 4, in step C), the method of equal-height stacking is as follows in formula (4):

[0093] (4);

[0094] wherein, is the soil height of the m-th section from underground towards the ground, is the height value for detecting the soil height of a certain section, is the set height value of a certain section of the soil height, is the soil data of the m-th section of the soil height detected. Further explanation is that through and the height values of each section of the soil height are set and detected. For example: sets and detects the soil height value of the first section and detects the soil data in the soil height of the first section. Similarly, sets and detects the soil height value of the m-th section and detects the soil data in the soil height of the m-th section, sets and detects the soil height value of the P-th section and detects the soil data in the soil height of the P-th section; the height values of each section can be set to be equal or unequal. Generally, the height values of each section are set to be equal and then the height values of each section and the soil data in each section are detected;

[0097] Formula (4) of this example is based on Soil data below the point or Area sampling soil collection model below the point For, the collection From a certain depth below the point to Soil data on the straight line formed between the points. From a certain depth below the point to The straight line between the points is divided into multiple segments, and the soil data of each segment is analyzed.

[0098] Based on formula (4), in step D), the high scatter point method is as follows in formula (5):

[0099] (5);

[0100] Wherein, Is the soil data of the Point, Is to detect the soil data of the Point, Is the operation of detecting the soil data at a point;

[0101] Is the category of the calibrated soil pollutant (i.e., setting the substance type of the soil pollutant), Is to detect and judge whether there is a soil pollutant at a point, Is the operation of calibrating the soil pollutant category;

[0103] Is to record whether there is a soil pollutant at each point, and evaluate the accumulation degree of soil pollutants in height of an area sampling soil collection model according to the soil pollutant conditions of each point.

[0104] Formula (5) is, for example: From a certain depth below the point to A straight line is formed between the points. Randomly select at least two or more points on the straight line, calculate whether there is soil pollution at each point. If there are more points with soil pollution among the points selected on the straight line, then The pollution of the area sampling soil collection model below the point is serious.

[0105] Therefore, for the degree of soil pollutant accumulation in height of a soil sampling model for regional site layout, the following method is adopted for evaluation:

[0106] Calculate the points with soil pollutants at the height of a soil sampling model for regional site layout; if the number of points with soil pollutants is greater than the set threshold number of points (i.e., the set threshold number of points can be 10 for the number of points with soil pollutants), then the degree of soil pollutant accumulation of a soil sampling model for regional site layout is large; if the number of points with soil pollutants is less than or equal to the set threshold number of points, then the degree of soil pollutant accumulation of a soil sampling model for regional site layout is small.

[0107] Example 6;

[0108] Based on all the above embodiments, in combination with Figure 3 and Figure 4 shown, in step E), the method of the proportion of the connection of the site layout in the area is as the following formula (6):

[0114] If the ratio is greater than 0.5, the treatment effect of the fixed area is poor; if the ratio is less than or equal to 0.5, the treatment effect of the fixed area is good.

[0115] As Figure 3 shown, the fixed area is set as the outer circle, and there are multiple inner circles inside the outer circle. Each inner circle is the area for laying out points. Figure 4 It is based on Figure 3 , and irregular areas are respectively added inside each inner circle. Each irregular area is the area for soil sampling of the contaminated area layout points.
