DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0052] Please see attached Figure 1

[0053] A carbon sequestration capacity value evaluation system for river and lake water ecosystems, comprising: a data acquisition module for collecting different types of vegetation samples and corresponding vegetation image data in a target area, wherein the target area is a river and lake water ecosystem;

[0054] The ground monitoring terminal is wirelessly connected to the data acquisition module, for example, by using wireless communication equipment, etc. The ground monitoring terminal includes:

[0055] A data analysis and processing module is used to process the collected vegetation samples to obtain carbon content data of different types of vegetation, and to obtain vegetation biomass data of different types of vegetation based on vegetation samples and vegetation image data, and then calculate carbon fixation capacity data of different types of vegetation through vegetation biomass data and carbon content data;

[0056] The carbon content data is obtained in the following way:

[0057] The vegetation samples are ground and processed, and the carbon content of the ground vegetation samples is determined using professional chemical analysis methods (such as combustion method, wet burning method, etc.);

[0058] Calculation of plant carbon sequestration capacity data: The carbon sequestration capacity of different types of vegetation is calculated based on the ratio of vegetation biomass to its carbon content. Specifically, after measuring the dry weight of vegetation samples (the collected vegetation samples are weighed, dried, etc. to obtain their dry weight) and carbon content, the values ​​are converted into units to obtain the organic carbon storage per unit area (such as per hectare) of each vegetation. This is a prior art and will not be described in detail here.

[0059] The evaluation module evaluates the carbon sequestration capacity value of the target area based on the total carbon sequestration capacity data of different types of vegetation.

[0060] Preferably, the ground monitoring terminal of this embodiment further includes:

[0061] The classification module is used to classify and store vegetation carbon content data, vegetation image data and biomass data of the same type of vegetation and display them through the display module, wherein the display module also displays corresponding carbon fixation capacity data.

[0062] The corresponding carbon fixation capacity data is classified, stored and displayed, which makes it easy to understand and compare the carbon fixation capacity data of different types of vegetation. For example, the vegetation with the best carbon fixation capacity data and the vegetation with the worst carbon fixation capacity data can be obtained, so as to manually adjust the vegetation in the target area to improve the carbon fixation capacity of the target area.

[0063] Preferably, the specific steps of obtaining vegetation biomass data of different types of vegetation according to vegetation samples and vegetation image data in this embodiment are:

[0064] The biomass data X1 is obtained by processing the collected vegetation samples;

[0065] The biomass data X2 is obtained by processing the vegetation image data;

[0066] Substitute the biomass data X1 and biomass data X2 into the following formula to calculate the vegetation biomass data Y:

[0067] Y=a×X1+b×X2

[0068] In the formula, a and b are weight coefficients;

[0069] The methods for obtaining the biomass data X1 and the biomass data X2 are both prior arts, for example, the specific methods are as follows:

[0070] Collect vegetation samples randomly or regularly in the target area, then take the vegetation samples back to the laboratory for drying, weighing and other treatments to remove moisture and obtain dry weight. Finally, calculate the biomass per unit area or volume based on the sampling area or volume to obtain data X1;

[0071] Extract relevant information (such as area, height, etc.) of vegetation from vegetation image data through image processing technology (such as image segmentation, feature extraction, etc.), and finally, establish a biomass estimation model based on this information to obtain data X2;

[0072] It should be noted that the sum of the above values ​​of a and b is 1 (or a certain fixed value).

[0073] In this way, the accuracy and reliability of biomass data of different types of vegetation can be improved.

[0083] The rotating mechanism 408 is disposed on the carrier 401 and is in driving connection with the annular frame 402, and is used to drive the annular frame 402 to rotate. The rotating mechanism 408, for example, includes a motor and a reducer disposed on the carrier 401, and a gear set (two sets of gears, one set of gears is sleeved on the output end of the reducer, and the other set is sleeved on the outer wall of the annular frame 402). The annular frame 402 can be rotated by the rotating mechanism 408 to realize the use conversion of different container bodies 406;

[0087] In this way, it is convenient to classify, collect and store different vegetation samples in the target area.

[0088] Please see attached Figure 5 -Attached Figure 7

[0089] Preferably, the cutting portion of this embodiment includes:

[0090] Two groups of cutting plates 415 are symmetrically arranged at the bottom of the container frame 407. The length of the cutting plates 415 is greater than the diameter of the container body 406, and the width is greater than the radius of the container body 406, so that the two cutting plates 415 can close the lower end of the container body 406 when the two opposite ends are in contact. A magnetic block matching the second electromagnetic block 411 is provided at the bottom of one cutting plate 415 facing the second electromagnetic block 411, and the other cutting plate 415 is connected to the container frame 407 through the third elastic member 416, which is used to drive the cutting plate 415 to reset when the second electromagnetic block 411 is powered off; and,

[0091] Two sets of racks 419 are symmetrically arranged on one side of the two sets of cutting plates 415 and extend along the width direction of the cutting plates 415, and a driven gear 1 420 is meshed between the two sets of racks 419. The driven gear 1 420 is rotatably arranged at the bottom of the container frame 407. Through the cooperation of the racks 419 and the driven gear 1 420, when one cutting plate 415 moves, the other cutting plate 415 moves synchronously in the opposite direction;

[0092] After the container body 406 descends to the preset position, the electromagnetic block 2 411 is turned on to attract the magnetic block, and then a cutting plate 415 moves outward. Under the action of the rack 419 and the driven gear 1 420, the other cutting plate 415 moves synchronously to extrude the elastic member 3 416. At this time, the lower end of the container body 406 is open, and the container body 406 is driven to be sleeved on the branches or leaves of the vegetation by controlling the telescopic device 410. Subsequently, the electromagnetic block 2 411 is closed, and the elastic member 3 416 drives the cutting plate 415 to reset and cut off the vegetation, so that part of the vegetation is in the container body 406.

[0093] Preferably, a hollow rod 423 is inserted into the top of the cover body 421 of this embodiment, and a bearing is provided at the connection between the hollow rod 423 and the cover body 421. The outer wall of the hollow rod 423 located in the container body 406 is provided with a plurality of groups of crushing blades and water spray holes, and the outer wall of the hollow rod 423 is sleeved with a driven gear 422. A rotator (not shown in the figure) is provided in the mounting shell 417. The rotator is, for example, a motor. The output end of the rotator passes through the top of the mounting shell 417 and is fixedly sleeved with a transmission gear meshing with the driven gear 422. By opening the rotator, the rotator drives the transmission gear, and the transmission gear drives the driven gear 422, thereby causing the hollow rod 423 in the corresponding container body 406 to rotate, and the hollow rod 423 crushes the vegetation sample in the container body 406 through the crushing blades, thereby reducing the burden of manual subsequent processing.

[0094] Preferably, the thickness of the transmission gear of this embodiment is greater than the thickness of the driven gear 422, and the top movable sleeve of the hollow rod 423 is provided with a connected joint, and the top of the joint abuts against the liquid outlet end of the circulation seat so that it can move downward with the container body 406. The circulation seat is connected to the corresponding movable block 404 through a connecting rod 418, and the movable block 404 adopts a sliding block and a vertical slide groove provided on the inner wall of the assembly groove 403 to slide in cooperation, and the sliding block is connected to an inner wall of the vertical slide groove through an elastic member 405. The top of the circulation seat is connected with a sleeve 414, and an annular plate coaxial with the annular frame 402 is provided above the sleeve 414. The annular plate is provided with a number of movable holes for inserting the sleeve 414, and the connection between the two can be sealed with a sealing ring. An annular hollow shell 413 is provided on the top of the annular plate through a bearing rotation sleeve.

The top inner wall of the annular hollow shell 413 is provided with an arc-shaped protrusion (not shown in the figure) for pushing the ball contact rod to move downward.

[0095] When there is no vegetation sample in the container body 406, the user can connect the external water supply equipment at the connection water pipe 412, and at the same time drive the annular frame 402 to rotate through the rotating mechanism 408. The rotation of the annular frame 402 drives the container body 406 through the movable block 404, and then the sleeve 414 drives the annular plate to rotate relative to the annular hollow shell 413. During the rotation process, the ball contact rod on the sleeve 414 intermittently contacts the arc-shaped protrusion, and then the sleeve 414, the circulation seat and the connecting rod 418 make the corresponding movable block 404 and the container body 406 move downward. When the ball contact rod is separated from the arc-shaped protrusion, the movable block 404 and the container body 406 are reset under the action of the elastic member 405. In this way, the container body 406 can reciprocate up and down, and the external water supply equipment can supply water to the container body 406. The liquid enters the annular hollow shell 413 through the connecting water pipe 412 and then enters each flow seat and the hollow rod 423 through the sleeve 414, and is then sprayed out from the water spray hole on its outer wall into the container body 406, thereby achieving efficient cleaning of the container body 406. Furthermore, the thickness of the transmission gear is greater than the thickness of the driven gear 422, and the driven gear 422 is always engaged with the transmission gear when the hollow rod 423 moves up and down, and when the annular frame 402 rotates, the driven gear 422 rotates around the transmission gear, so that the hollow rod 423 rotates in the container body 406, thereby facilitating the cleaning of the hollow rod 423 by the liquid in the container body 406, and effectively preventing the residual vegetation samples in the container body 406 from affecting the subsequent vegetation sampling work.
