[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] Please refer to Figure 1 , which shows a flowchart of a soil moisture analysis method based on the water absorption of vegetation in the present application.

[0026] As Figure 1 shown, the soil moisture analysis method based on the water absorption of vegetation specifically includes the following steps:

[0027] Step S101: Obtain the remote sensing image of the target plot, and input the remote sensing image into a preset area division model. The area division model outputs at least one target area, where the vegetation types on each target area are different.

[0028] In this step, obtain historical remote sensing images, and divide the historical remote sensing images into a training image set and an optimization image set. Among them, the historical remote sensing images in the training image set are marked with various area types, and the historical remote sensing images in the optimization image set are original soil environment images; establish an initial division model, input the historical remote sensing images in the training image set into the initial division model for training until the number of training times reaches the preset number of times, and then obtain a trained division model; input the original soil environment images in the optimization image set into the trained division model for recognition and optimization until the recognition accuracy reaches the preset accuracy, and then obtain the area division model.

[0029] Furthermore, input the remote sensing image of the target plot into the area division model, and identify the gray-scale features and texture features in the remote sensing image according to the area division model; determine whether the gray-scale features and texture features in the remote sensing image respectively match the preset gray-scale features and preset texture features of a certain area type; if they match successfully, perform area division on the remote sensing image to obtain at least one target area, otherwise continue to match.

[0030] Step S102: Divide a certain target area into at least one grid, where one grid contains a sub-plot and a vegetation block planted on the sub-plot.

[0031] Step S103: Calculate the water absorption of the vegetation blocks in each grid, and select a target vegetation block based on the magnitudes of the water absorptions.

[0032] In this step, ,

[0033] In the formula, μ i,j is the water absorption of the vegetation block i in the grid j , D i,j is the root length density of the vegetation block i in the grid j , v j is the volume of the grid j , k is the soil depth, Range i,j,k is the range of the vegetation block i in the grid j soil depth k range,θ k,j is the grid j at the soil depth k the matrix potential in θ k-1,j is the grid j at the soil depth k the matrix potential in -1 D j,k is the grid j at the soil depth k the root length density in ρ i,j is the vegetation block i in the grid j the volumetric root length density in;

[0034] ,

[0035] wherein Diameter i,j is the vegetation block i in the grid j the root diameter in Range i,k is the vegetation block i at the soil depth k the range in

[0036] It should be noted that, the water absorption amounts are sorted based on the numerical magnitudes to obtain a water absorption sequence; it is judged whether the numerical change amount between the first water absorption amount and the second water absorption amount is greater than a preset threshold, wherein, the first water absorption amount and the second water absorption amount are two adjacent water absorption amounts; if it is not greater than the preset threshold, then taking the first water absorption amount and the second water absorption amount as the demarcation points, the water absorption sequence is divided into a first water absorption sub - sequence and a second water absorption sub - sequence, wherein, the last water absorption amount in the first water absorption sub - sequence is the first water absorption amount, and the first water absorption amount in the second water absorption sub - sequence is the second water absorption amount; the vegetation block corresponding to the water absorption amount with the largest numerical value in the first water absorption sub - sequence is selected as the first target vegetation block, and a vegetation block corresponding to any water absorption amount in the second water absorption sub - sequence is selected as the second target vegetation block.

[0037] If it is greater than the preset threshold, then the first water absorption amount and the second water absorption amount are not taken as the demarcation points, and it is continued to judge whether the numerical change amount between the second water absorption amount and the third water absorption amount is greater than the preset threshold, wherein, the second water absorption amount and the third water absorption amount are two adjacent water absorption amounts.

[0038] For example, the water absorption amount a is 5 ml, the water absorption amount b is 6 ml, the water absorption amount c is 7 ml, the water absorption amount d is 8 ml, the water absorption amount e is 10 ml, the water absorption amount f is 10 ml, and the water absorption amount g is 10 ml. Then the first water absorption sub-sequence divided is: water absorption amount a, water absorption amount b, water absorption amount c, water absorption amount d, water absorption amount e. The second water absorption sub-sequence is: water absorption amount f, water absorption amount g.

[0039] Step S104, obtain the target soil moisture content of the target sub-plot in the target grid where the target vegetation block is located, and determine the other soil moisture contents corresponding to other water absorption amounts according to the ratio of the target soil moisture content to the target water absorption amount, where the target water absorption amount is the water absorption amount of the target vegetation block.

[0040] In this step, by comparing the masses of the target sub-plot before and after drying, the soil moisture content can be effectively obtained. For example, the target water absorption amount corresponding to the target vegetation block is 10 ml, and the target soil moisture content of the target plot corresponding to the target vegetation block is 100 ml / dm 3 , the target water absorption amount corresponding to a certain vegetation block is 8 ml, then the certain soil moisture content of a certain plot corresponding to a certain vegetation block is 80 ml / dm 3 .

[0041] Step S105, correct the other soil moisture contents according to a preset correction strategy to obtain the final corrected other soil moisture content, and superimpose the corrected other soil moisture content on the target soil moisture content to obtain the soil moisture content of the certain target area.

[0042] In this step, obtain the first target soil moisture content of the first target sub-plot in the target grid where the first target vegetation block is located, and determine the predicted soil moisture content corresponding to the second target water absorption amount of the second target vegetation block according to the ratio of the first target water absorption amount of the first target vegetation block to the first target soil moisture content; obtain the second target soil moisture content of the first target sub-plot in the target grid where the second target vegetation block is located, calculate the difference between the second target soil moisture content and the above to obtain the correction amount; according to the correction amount and the ratio of the first target water absorption amount of the first target vegetation block to the second target water absorption amount of the first target vegetation block, correct the soil moisture contents corresponding to each water absorption amount in the second water absorption sub-sequence to obtain the final corrected soil moisture content.

[0043] In a specific embodiment, since the water absorption amount of the vegetation will reach the upper limit, if the water content in multiple soils is relatively high at a certain time, then the water absorption amount of the vegetation will reach an upper limit value and fluctuate around the upper limit value, while the soil water content at this time may be in different situations.

[0044] Therefore, the water absorption amount sequence is divided into a first water absorption sub-sequence with continuous change and a second water absorption sub-sequence with no change or low change degree.

[0045] Select a first target vegetation block from the first water absorption sub-sequence and a second target vegetation block from the second water absorption sub-sequence. By taking the difference between the predicted soil moisture content and the actual soil moisture content (the second target soil moisture content) of the target plot corresponding to the second target vegetation block, a correction amount can be obtained. And according to the correction amount and the ratio of the first target water absorption amount to the second target water absorption amount of the first target vegetation block, the soil moisture content corresponding to each water absorption amount in the second water absorption sub-sequence is corrected to obtain the final corrected soil moisture content.

[0046] For example, the target water absorption amount corresponding to the first target vegetation block is 8 ml, and the target soil moisture content of the target plot corresponding to the first target vegetation block is 8 ml / dm 3 .

[0047] The target water absorption amount corresponding to the second target vegetation block is 8 ml, and the predicted soil moisture content of the target plot corresponding to the second target vegetation block is 80 ml / dm 3 , and the actual soil moisture content is 100 ml / dm 3 . Then the correction amount is 20 ml / dm 3 .

[0048] At this time, obtain a third vegetation block corresponding to a certain water absorption amount in the second water absorption sub-sequence. The water absorption amount corresponding to the third vegetation block is 8.5 ml. Then the predicted soil moisture content of the plot corresponding to the third vegetation block is 85 ml / dm 3 , and the predicted soil moisture content is corrected based on the correction amount to obtain the final corrected soil moisture content of 115 ml / dm 3 .

[0049] In summary, the method of the present application calculates the water absorption amounts of the vegetation blocks in each grid, selects target vegetation blocks based on the magnitudes of the water absorption amounts, obtains the target soil moisture content of the target sub-plot in the target grid where the target vegetation block is located, determines the other soil moisture contents corresponding to other water absorption amounts according to the ratio of the target soil moisture content to the target water absorption amount, corrects the other soil moisture contents according to the preset correction strategy to obtain the final corrected other soil moisture contents, and superimposes the corrected other soil moisture contents with the target soil moisture content to obtain the soil moisture content of a certain target area, which can analyze the water content in the soil more accurately. Compared with the traditional method of dividing the target plot into grids and obtaining the soil water content in each grid, it can reduce the workload of the staff.
