They are the objects of environmental monitoring research. Most environmental pollutants are produced by human production and life activities. Some substances were originally useful substances in production, or even essential nutrients for humans and organisms. Due to underutilization, they are discharged in large quantities, which not only causes a waste of resources, but also may become environmental pollutants.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] like Figure 1As shown, the threshold concentration calculation system for ecotoxicity effects of environmental pollutants includes a concentration calculation platform, which is communicatively connected to a regional monitoring module, a growth analysis module, a comprehensive analysis module and a storage module.

[0031] The regional monitoring module is used to conduct regional monitoring and analysis of pollutant concentrations in ecological monitoring areas: the ecological monitoring area is divided into several monitoring areas, a monitoring cycle is generated, and the atmospheric data DQ, water data ST and soil data TR of the monitoring area within the monitoring cycle are obtained. The process of obtaining atmospheric data DQ includes: setting up several atmospheric monitoring points in the monitoring area, monitoring the atmospheric pollution concentration values ​​of the atmospheric monitoring points in real time during the monitoring cycle, and marking the maximum atmospheric pollution concentration values ​​of all atmospheric monitoring points within the monitoring cycle as atmospheric data DQ; the process of obtaining water data ST includes: setting up several water monitoring points in the monitoring area, monitoring the water pollution concentration values ​​of the water monitoring points in real time during the monitoring cycle, and marking the maximum water pollution concentration values ​​of all water monitoring points within the monitoring cycle as water data ST; the process of obtaining soil data TR includes: setting up several soil monitoring points in the monitoring area, monitoring the soil pollution concentration values ​​of the soil monitoring points in real time during the monitoring cycle, and marking the maximum water pollution concentration values ​​of all water monitoring points within the monitoring cycle as water data ST. The maximum value of the soil pollution concentration value of the soil monitoring point is marked as soil data TR; the pollution coefficient WR of the monitoring area during the monitoring period is obtained by the formula WR=a1*DQ+a2*ST+a3*TR. The pollution coefficient is a numerical value that reflects the overall ecological pollution degree of the monitoring area during the monitoring period. The larger the value of the pollution coefficient, the higher the overall ecological pollution degree of the monitoring area during the monitoring period; a1, a2 and a3 are all proportional coefficients, and a3>a2>a1>1; the pollution coefficient WR of the monitoring area is sent to the concentration measurement platform, and the concentration measurement platform sends the received pollution coefficient WR of the monitoring area to the comprehensive analysis module; regional monitoring and analysis of pollutant concentrations in the ecological monitoring area is carried out, and the accuracy of pollutant concentration monitoring results is improved by regional division. At the same time, a number of ecological pollution parameters are combined for comprehensive analysis and calculation to obtain the pollution coefficient of the monitoring area, so as to feedback the ecological pollution status in the monitoring area through the pollution coefficient, and provide data support for threshold concentration measurement.

[0032] The growth analysis module is used to monitor and analyze the growth status of plants in the ecological monitoring area: take images of plants in the monitoring area and obtain monitoring images, divide the monitoring images into several sub-areas, enlarge the monitoring images into pixel grid images and perform grayscale transformation. Grayscale transformation refers to a method of changing the grayscale value of each pixel in the source image point by point according to a certain target condition and a certain transformation relationship. The purpose is to improve the image quality and make the image display effect clearer. The grayscale transformation processing of the image is a very basic and direct spatial domain image processing method in image enhancement processing technology. It is also an important part of image digitization software and image display software; obtain the variety of plants planted in the planting area and the planting growth time, and retrieve the corresponding grayscale range in the storage module according to the variety of plants planted and the planting growth time. The average value of the maximum and minimum values ​​of the grayscale range is marked as the gray table value, and the grayscale values ​​of the pixel grids in the sub-area are summed and averaged to obtain the gray display value of the sub-area, and the absolute value of the difference between the gray display value and the gray table value is marked as the gray difference value of the sub-area, and the gray difference values ​​of all sub-areas are summed. The gray mean value of the monitoring area is obtained by taking the average value, and a gray difference set is established by the gray difference values ​​of all sub-areas. The gray wave value is obtained by performing variance calculation on the gray difference set. The gray mean threshold and gray wave threshold are obtained through the storage module. The gray mean value and gray wave value of the monitoring image are compared with the gray mean threshold and gray wave threshold respectively: if the gray mean value is less than the gray mean threshold and the gray wave value is less than the gray wave threshold, it is determined that the growth state of the plants in the monitoring area meets the requirements, and the corresponding monitoring area is marked as a normal area; otherwise, it is determined that the growth state of the plants in the monitoring area does not meet the requirements, and the corresponding monitoring area is marked as an abnormal area, and the abnormal area is sent to the concentration measurement platform. After receiving the abnormal area, the concentration measurement platform sends the abnormal area to the comprehensive analysis platform; the growth state of plants in the ecological monitoring area is monitored and analyzed, and the gray mean value and gray wave value of the monitoring area are obtained by image processing of the monitoring image, so that the growth state and growth difference of the plants in the monitoring area are fed back through the gray mean value and the gray wave value, and the standard grayscale range is obtained in combination with the plant variety and growth time, so as to improve the accuracy of the plant growth monitoring results.

[0033] The comprehensive analysis platform is used to measure and analyze the threshold concentration of ecotoxicity effects in ecological monitoring areas: the ratio of the number of abnormal areas in the monitoring period to the number of monitoring areas is marked as the abnormal coefficient of the monitoring period, the abnormal threshold is obtained through the storage module, and the abnormal coefficient of the monitoring period is compared with the abnormal threshold: if the abnormal coefficient is less than the abnormal threshold, the monitoring period is marked as a normal period; if the abnormal coefficient is greater than or equal to the abnormal threshold, the monitoring period is marked as an abnormal period; the minimum value of the pollution coefficient WR of all monitoring areas in the abnormal period is marked as the pollution value of the abnormal period, and the pollution coefficient of all abnormal periods in the last L1 monitoring periods is marked as the pollution value of the abnormal period. The minimum value of the pollution value is marked as the pollution threshold, L1 is a numerical constant, and the specific value of L1 is set by the management personnel; the pollution threshold is sent to the concentration measurement platform, and after receiving the pollution threshold, the concentration measurement platform sends the pollution threshold to the storage module and the mobile phone terminal of the management personnel; the threshold concentration of the ecotoxicity effect in the ecological monitoring area is measured and analyzed, and the pollution value of the abnormal period is obtained by analyzing the pollution coefficient of the monitoring area in the abnormal period, so as to obtain the pollution threshold according to the pollution value of the recent abnormal period, and continuously optimize and update the threshold concentration in combination with the growth status of the plant to improve the rationality of setting the threshold concentration of the toxic effect.

[0038] Step 3: Calculate and analyze the threshold concentration of ecotoxicity effects in the ecological monitoring area: mark the ratio of the number of abnormal areas within the monitoring period to the number of monitoring areas as the abnormal coefficient of the monitoring period, mark the monitoring period as an abnormal period or a normal period according to the numerical value of the abnormal coefficient, and obtain the pollution threshold through the pollution value of the abnormal period.

[0039] The method for calculating the threshold concentration of ecotoxicity effect of environmental pollutants is to conduct regional monitoring and analysis on the pollutant concentration in the ecological monitoring area during operation: the ecological monitoring area is divided into several monitoring areas, a monitoring period is generated, the atmospheric data DQ, water data ST and soil data TR of the monitoring area within the monitoring period are obtained, and numerical calculations are performed to obtain the pollution coefficient WR of the monitoring area within the monitoring period, and the pollution coefficient WR of the monitoring area is sent to the comprehensive analysis module through the concentration measurement platform; the plants in the monitoring area are imaged to obtain monitoring images, the monitoring images are processed to obtain the gray mean and gray wave values ​​of the monitoring area, and the monitoring area is marked as a normal area or an abnormal area according to the values ​​of the gray mean and gray wave values; the ratio of the number of abnormal areas within the monitoring period to the number of monitoring areas is marked as the abnormal coefficient of the monitoring period, the monitoring period is marked as an abnormal period or a normal period according to the numerical value of the abnormal coefficient, and the pollution threshold is obtained according to the pollution value of the abnormal period.
