Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes the device, system and method for determining the species of submerged plants that can be restored in the water area of ​​the embodiment of the present application with reference to the accompanying drawings. In response to the problems mentioned in the above background technology, the present application provides a device for determining the species of submerged plants that can be restored in the water area, in which the suspended matter concentration, water depth and geographical information of the target water area are obtained through a suspended matter sensor, a water depth sensor and a positioning device, and the light compensation point threshold of the surviving submerged plants can be quickly calculated through a communication device and a processing device, and then the relevant submerged plant species are output. Therefore, combined with the local lighting conditions, the light tolerance of various submerged plants and the influence of suspended matter on underwater light intensity, the judgment is more accurate and fast, and can be applied to water body judgment in different areas, which can provide technical support for water ecological restoration projects, and solves the problems of estimating the underwater light conditions for submerged plants to be restored by the ratio of water body transparency to water depth in the related technology, and the poor accuracy of the judgment results due to differences in sunlight intensity, submerged plant species, etc., and low applicability.

[0030] Specifically, Figure 1 This is a block diagram of a device for determining the species of submerged plants that can be restored in water areas provided in an embodiment of the present application.

[0031] like Figure 1 As shown, the device 100 for determining the species of submerged plants that can be restored in water areas includes: a suspended matter sensor 1, a water depth sensor 2, a positioning device 3, a communication device 6 and a processing device 4.

[0032] Among them, the suspended matter sensor 1 is used to obtain the suspended matter concentration information of the target water area; the water depth sensor 2 is used to obtain the water depth information of the measurement point of the target water area; the positioning device 3 is used to obtain the geographical information of the target water area; the communication device 6 is used to upload the geographical information to the cloud server and obtain the average daily light intensity sent by the cloud server, wherein the cloud server obtains the meteorological data of the target water area based on the geographical information, and calculates the average daily light intensity of the area where the target water area is located based on the meteorological data; the processing device 4 is used to calculate the light compensation point value of the target water area based on the suspended matter concentration information, the water depth information of the measurement point and the average daily light intensity, and determine the submerged plant species that can be restored in the target water area based on the light compensation point value of the target water area.

[0033] The communication device 6 is a wireless signal transmission and receiving device.

[0034] It is understood that the apparatus for determining restorable submerged plant species in a water area according to the present embodiment of the present application can obtain suspended matter concentration, water depth, and geographic information of the target water area through suspended matter sensor 1, water depth sensor 2, and positioning device 3. Combined with the line signal transmission and receiving device and processing device 4, it can rapidly calculate the light compensation point threshold for viable submerged plants and then output the relevant submerged plant species. Compared to the prior art method of estimating using the transparency-to-water-depth ratio, this method is more accurate and rapid, applicable to water bodies in different regions, and can provide technical support for aquatic ecological restoration projects.

[0035] In one embodiment of the present application, the processing device 4 is also used to: determine the light attenuation coefficient value of the target water area based on the suspended matter concentration information; calculate the light compensation point value of the target water area based on the light attenuation coefficient value, the water depth information of the measurement point and the average daily light intensity.

[0036] In the embodiment of the present application, the light attenuation law of the light intensity underwater conforms to Beer's law, that is:

[0037]

[0038] Among them, I t is the light intensity at a water depth of t, I0 is the average daily light intensity on the water surface, k d is the light attenuation coefficient value.

[0039] Due to the absorption and scattering of underwater light by suspended matter, the light attenuation is found in the process of actual investigation and literature collection. d ) has a good regression correlation with the total suspended solids concentration (SS). In actual water quality monitoring, the process of obtaining the light attenuation coefficient is relatively complicated. Therefore, the SS relationship can be used to express the attenuation of light underwater. The calculation formula of the light attenuation coefficient value is:

[0040] kd =a*SS b ,

[0041] Where a and b are constants, and SS is the total suspended solids concentration. In actual implementation, a and b can be used to construct the relationship between SS and k by measuring the light attenuation coefficient of water bodies with different suspended solids concentrations. d The correlation relationship is obtained and entered into the device in advance. For example, the reference value of a can be 9.28, and the reference value of b can be -0.679, without specific limitation.

[0042] Furthermore, the embodiment of the present application can obtain relevant geographic information of the water area based on the positioning device 3, and send the relevant geographic information to the cloud server through the wireless receiving and transmission device. The cloud server calculates the local average daily light intensity I0 based on the meteorological data (sunlight radiation), and returns the I0 data to the water area restorable submerged plant species determination device 100. At the same time, the water depth sensor 2 can obtain the water depth information D of the measurement point.

[0043] Furthermore, the processing device 4 can calculate the light compensation point value of the target water area according to the light attenuation coefficient value, the water depth information of the measurement point, and the average daily light intensity. The calculation formula of the light compensation point value of the target water area is:

[0044]

[0045] Among them, I0 is the average daily light intensity, D is the water depth information of the measurement point, k d is the light attenuation coefficient value.

[0046] In one embodiment of the present application, Figure 2 As shown, the device 100 for determining the species of submerged plants that can be restored in water areas further includes: a storage device 5 .

[0047] The storage device 5 stores light compensation point values ​​of various submerged plants.

[0048] It is understandable that the light compensation point value (I p ) refers to the light radiation intensity when the amount of CO2 absorbed by photosynthesis and the amount of CO2 produced by respiration of submerged plants reach a balance under a certain light intensity. That is, when the light radiation intensity is lower than this value, submerged plants are difficult to survive. The water depth at the same light intensity is called the light compensation depth (D p ), and the relationship between it and the light compensation point is:

[0049] D p =[lnI0-lnI p ] / k d ;

[0050] By comparing the D pThe size of the actual water depth can be used to determine whether the submerged plant can survive under the lighting conditions of the water area.

[0051] The storage device of the embodiment of the present application stores in advance the light compensation point values ​​(I p ) information, light compensation point value (I p ) Information can be obtained by consulting literature or laboratory.

[0052] In one embodiment of the present application, Figure 2 As shown, the apparatus 100 for determining submerged plant species that can be restored in a water area further includes a display device 7 for displaying the submerged plant species that can be restored in the target water area. The processing device 4 searches the storage device 5 for submerged plant species whose light compensation point value is less than the light compensation point value of the target water area based on the light compensation point value of the target water area.

[0053] It is understandable that the embodiment of the present application can compare the calculated light compensation point value I of the target water area with the light compensation point values ​​(I p ) one by one, and output the light compensation point (I p ) is smaller than the light compensation point value of the target water area, and is displayed on the display device 7. Thus, by combining the local light conditions, the light tolerance of various submerged plants, and the influence of suspended matter on underwater light intensity, it is possible to quickly determine and display the submerged plant species that can survive in the water area.

[0054] According to the device for determining the species of submerged plants that can be restored in water areas proposed in the embodiment of the present application, the suspended matter concentration, water depth, and geographical information of the target water area are obtained through a suspended matter sensor, a water depth sensor, and a positioning device, and the light compensation point threshold of the surviving submerged plants can be quickly calculated through a communication device and a processing device, and then the relevant submerged plant species are output. Thus, combined with the local lighting conditions, the light tolerance of various submerged plants, and the influence of suspended matter on underwater light intensity, the judgment is more accurate and fast, and can be applied to water body judgment in different areas. It can provide technical support for water ecological restoration projects and solve the problem in related technologies of estimating the underwater light conditions for submerged plants to be restored by the ratio of water body transparency to water depth. Due to differences in sunlight intensity, submerged plant species, etc., the judgment results are poor in accuracy and have low applicability.
