[0006] Preferably, the environmental medium includes air, soil and water; the first detection data set includes an air first detection data set, a soil first detection data set and a water resource first detection data set.

[0007] Preferably, the physical and chemical components of the first detection data set of each environmental medium are identified to determine the substances present in the corresponding environmental medium, and each substance component is marked as a corresponding component index item; Based on the physical and chemical properties of the substances, pollutant identification is carried out on the component index items, the substance components determined to be pollutants are marked as pollutant index items, and the index data of the corresponding pollutant index items are obtained; Based on the physical and chemical properties of the substances, a hazard judgment is carried out on the pollutant index items to obtain a first hazard assessment index; Based on the first hazard assessment index and the index data of the corresponding pollutant index items, the harmfulness of the content of the pollutant in the corresponding environmental medium to the environment is determined to obtain a second hazard assessment index.

[0008] Preferably, in step S31, when it is determined that there are pollutants, continuous physical and chemical index collection is carried out on each environmental medium to obtain a second detection data set; In step S32, according to the collection time sequence of the data in the second detection data set, the data at two adjacent time points are compared in terms of substance components and pollutant contents to determine the component changes of the substances and the pollutant data changes in each environmental medium; In step S33, if the substance components of any one environmental medium change, the changed substances are marked as variable items, and the variable items are compared with the pollutant data changes in each environmental medium to determine the relationship between the pollutant data changes and the component changes of the corresponding environmental medium, and the impact of the pollutant on the environment is determined according to the change relationship and the harmfulness of the pollutant.

[0009] Preferably, based on the time data, a judgment is made on the variable items of the same environmental medium to determine whether the variable items are new substances. The variable items of new substances are marked as substance increase items, and the variable items of non-new substances are marked as conventional substance items; Based on the molecular chemical formula of the substances, the variable items at the same time point are matched in terms of substance elements to determine whether the substance increase items have the same pollutant element as the conventional substance items. The substance increase items and the conventional substance items with the same pollutant element are marked as a substance transformation group; Based on the molecular chemical formula, a comparison judgment is made on the change amounts of the substances in the substance transformation group at the same time point to determine whether the quantitative relationship between the reduction amount of the substances in the conventional substance items and the increase amount of the substances in the substance increase items satisfies the conversion relationship of the molecular chemical formula to obtain a comparison result; Determine the conversion efficiency of the substance based on the comparison result, and determine the environmental impact of the pollutant based on the comparison result and the harmfulness of the pollutant.

At the same time, by judging the pollutants for the detected substance components and the harmfulness of the pollutants themselves to the environment, and combining with the environmental treatment methods for different substances, finally determine the environmental impact of the pollutants, and then determine the evaluation coefficient of the corresponding index item in the evaluation equation according to the impact, so that the evaluation result is more accurate and effective when evaluating the environmental health quality according to the collected detection data set; With the help of the molecular chemical formulas of different substances, trace the pollution elements of the pollutants, determine the continuous existence form of the pollution elements in this environment, and then determine the purification and conversion conditions of the current environment for the pollutants. At the same time, because the same pollution element has different harms to the environment in different forms of existence, by determining the environmental impact when the pollutant is stable in this environment, the accuracy of the evaluation according to the built - in evaluation equation is higher. Description of the Drawings

[0015] Figure 1This is the flowchart of the steps of the ecological environment health quality assessment method for this embodiment. Detailed implementation manners

[0016] The following further elaborates on this application in conjunction with the attached Figure 1 drawings.

[0017] An embodiment of this application discloses an ecological environment health quality assessment method.

[0018] Embodiment: As Figure 1 shown, an ecological environment health quality assessment method of the present invention includes: S1. Detect the physical and chemical indexes of various environmental media to obtain the first detection data set of the corresponding environmental media; wherein, the first detection data set includes detection index items and detection index data; wherein, the environmental media include air, soil, and water; the first detection data set includes the air first detection data set, the soil first detection data set, and the water resource first detection data set.

[0019] By collecting the relevant data of the environment through three environmental media of air, soil, and water, the finally evaluated data can more accurately reflect the environmental health quality of the region, making the evaluation result more accurate.

[0020] By collecting in multiple regions and ranges for each environmental medium, the first detection data set collected can more accurately reflect the real situation of the environment, improving the data quality, and further making the evaluation result more accurate and true when evaluating the environmental health quality of this data.

[0021] S2. Based on the environmental media, judge the pollutants and evaluate the harmfulness of the pollutants for the first detection data set of each environmental medium to determine the harmfulness of the pollutants; Specifically: S21. Identify the physical and chemical components of the first detection data set of each environmental medium to determine the substance components present in the corresponding environmental medium, and mark each substance component as the corresponding component index item; S22. Based on the physical and chemical properties of the substances, identify the pollutants for the component index items, mark the substance components determined to be pollutants as pollutant index items, and obtain the index data of the corresponding pollutant index items; S23. Judge the harmfulness of the pollutant index items based on the physical and chemical properties of the substances to obtain the first harm assessment index; S24. Based on the first harm assessment index and the index data of the corresponding pollutant index items, determine the harmfulness of the content of the pollutant in the corresponding environmental medium to the environment to obtain the second harm assessment index. Among them, the first harm assessment index and the second harm assessment index are collectively referred to as the harmfulness of the pollutants.

[0022] When evaluating the environmental health quality, it is first necessary to determine whether there are pollutants in the corresponding environmental medium. Therefore, it is necessary to confirm the pollutants. By identifying the material components of the first detection data set collected, determine the material components contained in the corresponding environmental medium, and then judge the harmfulness of the material components to determine which substances among all the material components in the environmental medium will have an impact on the environment, and mark the material costs. When judging the harmfulness of pollutants, not only the harmfulness of the substance itself but also the harmfulness caused by the content of the substance should be considered. For example, a grain of salt placed in a water cup may not affect the taste of the water in the cup, while if it is a spoonful of salt, it will affect the taste of the water. By judging the harmfulness of various pollutants once, the harm to the environment caused by various pollutants can be uniformly quantified, and then by determining the content of the pollutants contained in the environment, the harm that the pollutant can cause under the current environment can be further clarified, making the evaluation result more accurate and effective during the process of evaluating the environmental impact of pollutants, and thus making the evaluation of environmental health quality more accurate.

[0023] S3. When it is determined that there are pollutants, collect data of each environmental medium for multiple time periods, and determine the impact of the pollutants on the environment according to the harmfulness of the pollutants and the data collected in multiple time periods in each environmental medium; Specifically: S31. When it is determined that there are pollutants, continuously collect physical and chemical indicators of each environmental medium to obtain a second detection data set; S32. According to the time sequence of data collection in the second detection data set, compare the data at adjacent two time points in terms of material components and pollutant content to determine the component changes of substances and pollutant data changes in each environmental medium; S33. If there is a change in the material components of any environmental medium, mark the changed substance as a variable item, compare the variable item with the pollutant data changes in each environmental medium, determine the relationship between the pollutant data changes and the component changes of the corresponding environmental medium, and determine the impact of the pollutants on the environment according to the change relationship and the harmfulness of the pollutants.

[0024] It also includes: S331. Based on time data, judge the variable items of the same environmental medium to determine whether the variable item is a new substance, mark the variable item of the new substance as a substance addition item, and mark the variable item of the non - new substance as a conventional substance item; S332. Based on the molecular chemical formula of the substance, match the changed items at the same time point with the substance elements, and determine whether the substance increase item has the same pollutant element as the conventional substance item. Mark the substance increase item and the conventional substance item with the same pollutant element as the substance conversion group. For example, the molecular chemical formula of water is H 2 2 2 O, and the molecular chemical formula of oxygen is O

[0025] 2, both of which contain oxygen element (O).

[0026] S333. Based on the molecular chemical formula, compare and judge the change amounts of the substances in the substance conversion group at the same time point, and determine whether the quantitative relationship between the decrease amount of the substance in the conventional substance item and the increase amount of the substance in the substance increase item satisfies the conversion relationship of the molecular chemical formula to obtain the comparison result. The comparison results include: 1. The data relationship between the actual decrease amount and the increase amount is greater than the conversion relationship, indicating that more is converted and less is consumed. Furthermore, it indicates that there is a continuous output source in the conventional item, and the output efficiency of this continuous output source is lower than the conversion efficiency. 2. The data relationship between the actual decrease amount and the increase amount is less than the conversion relationship, indicating that less is converted and more is consumed. Furthermore, it indicates that the environment not only has a conversion effect on the increase item / conventional item but also has a purification effect, and at least one purification efficiency can be determined according to the chemical formula. 3. The data relationship between the actual decrease amount and the increase amount is equal to the conversion relationship, indicating that the converted and consumed are converted according to the molecular chemical formula 1:1. Therefore, there is no purification efficiency, and the conversion efficiency can be determined according to the conversion amount.

[0027] When there are changes in the substance composition or pollutant data in an environmental medium, judge the changes in the substance composition and pollutant data in the other environmental media at the same time point. When there are also changes in the substance composition or pollutant data in other environmental media, based on the chemical relationship, determine whether the pollutants in the multiple environmental media with simultaneous changes in the substance composition or pollutant data are the same pollutant element. If it is determined to be the same pollutant element, then according to the increase amount of the substance in one environmental medium and the decrease amount of the substance in another environmental medium, and the molecular chemical relationship, determine the conversion relationship of the same pollutant element among the multiple environmental media, and determine the impact on the environment according to the harmfulness of the converted substance.

[0028] When it is determined that there are pollutants in the environmental medium, continuous data collection of the environmental medium is carried out to clarify the change in the quantity of pollutants. By comparing the data collected at multiple time points of the same environmental medium for adjacent time points, the change in the material composition and the change in the pollutant content in the environmental medium are determined. When a new substance is added or a new substance is reduced or the content of pollutants increases or decreases in an environmental medium, it indicates the presence of the production or elimination of the substance in the environmental medium. Therefore, by making the same judgment on the material changes in other environmental media, it is determined whether the increase in the substance in one environmental medium is caused by the reduction of the substance in another environmental medium, so as to clarify the reasons for the change in the material composition and the change in the pollutant data in the environmental medium, and then determine the impact of the change result on the environment according to the reasons. For example, for sulfides, when it changes from a weak acid to a strong acid, the harmfulness increases, so the impact on the environment increases. On the contrary, when it changes from a strong acid to a weak acid, the harmfulness decreases and the impact on the environment decreases. Similarly, if a substance changes from a gas to a liquid and then to a solid, the impacts brought by different forms are also different, and then the impact of the substance on the environment is comprehensively judged.

[0029] S4. If the pollutants do not affect the environment, then the environmental health quality is judged according to the first detection data set collected, and the environmental health quality is determined and output; specifically: the first detection data set collected at the current time point is input into the evaluation equation of the corresponding environmental medium to determine the corresponding environmental health quality and output. Since there are no pollutants in the environment, that is, there is no environmental damage source, the data collected currently is the stable data of the current environment. Therefore, by analyzing and judging according to the collected data, the health degree of the current environment can be evaluated. Among them, the evaluation equation can be: , where y is the evaluation data of the corresponding environmental health quality, (M1, M2,..., Mn) are the material composition index items in the environmental medium, (a1, a2,..., an) are the initial weights of the corresponding substances, (b1, b2,..., bn) are the increase efficiencies of the corresponding substances, (c1, c2,..., cn) are the purification efficiencies of the corresponding substances, and (d1, d2,..., dn) are the conversion efficiencies of the corresponding substances.

[0030] S5. If the pollutant has an impact on the environment, then judge the pollution source, and comprehensively judge the detection data set collected at the current time point according to the characteristics of the pollution source to determine and output the environmental health quality. Similarly, since there are pollutants in the environment, it indicates that the pollution will damage the environment. Therefore, it is necessary to judge the pollution source to determine whether the pollution will cause continuous damage to the environment. If it causes continuous damage to the environment, then when evaluating the environmental health quality, the continuous damage of the pollutant, that is, the vicious cycle, needs to be considered. On the contrary, if it does not cause continuous damage to the environment, then when evaluating the environmental health quality, the continuous damage of the pollutant does not need to be considered, making the final evaluation result more accurate and effective.

[0031] Specifically: S51. If it is determined that there is a pollutant having an impact on the environment, then construct a substance distribution plane for the first detection data set at the same time point in the same environmental medium according to the environmental medium where the pollutant is located to obtain a substance distribution map on the same plane; S52. Judge the substance in the substance distribution map according to the second detection data set to determine the pollution source of the pollutant; S53. Determine the nature of the pollution source according to the impact of the pollutant on the environment, and determine the environmental health quality under the action of the pollutant according to the nature of the pollution source and the index data of the corresponding pollutant. Among them, the nature of the pollution source includes continuous pollution that produces pollutants for a long time and non - continuous pollution that only produces pollutants once.

[0032] Since each sensor has corresponding position information when detecting the physical and chemical indexes of the environmental medium, the substance distribution situation in the corresponding area can be determined according to the position information of the sensor. By establishing a substance distribution map for the detection data at the same time point and then comparing the substance distribution maps at multiple time points with each other, the pollution source of the pollutant can be determined. When the pollutant diffuses from the pollution source to other places, its distribution is regular. For example, the higher the pollutant concentration is, the closer it is to the pollution source, and the lower the pollutant concentration is, the farther it is from the pollution source. Similarly, if there is a pollution source, the content of the pollutant in this area will increase continuously. If there is no pollution source, the pollutant will continue to diffuse to cover a larger area, so that the pollutant content per unit area will decrease. Through the above theory, the judgment of the pollution source is more accurate. Furthermore, when evaluating the environment according to the nature of different pollutants, the obtained evaluation result is more accurate.

[0033] When the pollution source of pollutants is continuous pollution, the pollution increase efficiency is determined by the increase amount of pollutants, and then the purification efficiency and conversion efficiency of the corresponding pollutants are determined according to the comparison result. The evaluation coefficient of the corresponding pollutants in the built-in evaluation equation is adjusted according to the pollution increase efficiency, purification efficiency and conversion efficiency of the corresponding pollutants, and then the currently collected current detection data set is substituted into the corresponding index items in the evaluation equation, and the health quality data of the current environment is comprehensively calculated and output. This makes the evaluation result more accurate and effective.

[0034] Compared with the existing ecological environment health quality evaluation methods, the present invention improves the accuracy of the evaluation result of the environment health quality.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
