[0040] To this end, the present invention also proposes a method for modeling the collected surface matrix data, and the method comprises the following steps:

[0041] 1. Data processing:

[0042] 1.1 Soil data

[0043] Combined with the distribution characteristics of land use and irrigation methods, soils of different soil types, different land use types, and different irrigation methods were selected. The farmland sample plots and the adjacent natural background original desert sample plots were grouped into one group, with a total of 2 groups of profile sample points (S1&S2, S3&S4). The specific conditions of the sample points are shown in Table 1 (Table 1 is the land use type and characteristics of the sampling points); soil samples were collected at intervals of 20 cm until the groundwater level, and a total of 118 profile samples were collected.

[0044] The collected soil samples were placed in a ventilated room to dry naturally, fully ground, and sieved through a 2mm soil sample sieve for later use; the composition of each ion was determined according to the test method in the soil agricultural chemical analysis method, and the stratified description of the changes in the soluble salt ions and salt content of the soil with depth. The data on hydrogeology, plant roots, etc. were derived from the historical survey data of the Desert Ecosystem Scientific Observation and Research Station.

[0045] Table 1 Land use types and characteristics of sampling points

[0046]

[0047] 1.2 Meteorological and remote sensing data

[0048] The meteorological data used include temperature and precipitation data, and the remote sensing data include solar radiation, DEM, NDVI, and vegetation cover type data.

[0049] 2. Research methods:

[0050] 2.1 Model Building

[0051] Following geological laws, the data types obtained after data collection, including meteorological and remote sensing data, soil data, and rock data, are combined to build a database. After the database is established, a three-dimensional model is established through the software platform. After the three-dimensional model is established, the validity of the model is verified (for example: repeated triangle verification, invalid edge triangle verification, self-intersecting triangle verification, open edge triangle verification, etc.).

[0052] The specific construction process includes:

[0053] Various soil data are formed into initial grid elements. After each type of data is extracted to generate the corresponding high-precision grid element model, these elements are merged.

[0054] The initial grid elements are fused and uniformly coded to form new multi-level, multi-precision grid data elements. When performing complex modeling, the surface matrix layer attribute conditions and spatial area conditions are used to quickly search for surface matrix layer modeling data source elements within the three-dimensional ellipsoid, and then high-performance parallel computing attribute modeling is performed.

[0055] The basic composition of three-dimensional model elements includes the following: surface matrix layer attributes, which are used to describe the texture and test data of surface matrix layer elements, including surface matrix texture attributes, land stratification attributes, soil color attributes, chemical and biological indicator attributes, etc.; surface matrix grid model, which is composed of matrix layer grid bodies with non-empty, finite and continuous characteristics. The matrix layer grid model is also called a high-precision grid model; the vector model (converted from the raster model) surface matrix layer, which is composed of a list of triangular faces. The normals of the triangular faces in the matrix layer should be consistent. The matrix layer has its own point set, and the direction of the matrix layer boundary line is consistent with the direction of the triangular faces in the face. The matrix layer is the basic unit that constitutes the matrix layer block, and the topological relationship between multiple matrix layers is expressed by the matrix layer stratification line.

[0056] There can be multiple geometric bodies of the same type in a surface matrix element. The surface matrix layer element geometry plus the surface matrix layer attributes constitute the surface matrix layer element. The topological relationship between the three-dimensional elements can be reconstructed by model calculation through the three-dimensional modeling platform. The topological association modes in different three-dimensional surface matrix geological body elements include: elements and elements, geometric bodies and elements, geometric bodies and geometric bodies, lines and surfaces, nodes and lines, geometric bodies and high-precision continuous grid bodies, etc., and many-to-many situations can occur between them.

[0057] Resample each modeling data to the initial grid input data required for interpolation. The coarsening methods used for continuous data include arithmetic mean, harmonic mean, ensemble mean, root mean square method, median, maximum, minimum, midpoint picking, and random picking; the coarsening methods used for discrete data include mode method, median, maximum, minimum, midpoint picking, and random picking.

[0058] A high-performance parallel computing attribute interpolation method is selected according to the modeling data type. The attribute interpolation algorithms used for continuous data include simple kriging algorithm, ordinary kriging algorithm, LVM kriging algorithm, and sequential Gaussian kriging algorithm; the attribute interpolation algorithms used for discrete data (test data) include indicator kriging algorithm and sequential indicator simulation algorithm.

[0059] The model results are restored using DEM elevation data. The modeling results after the grid correction operation are transformed back to the original undulating trend grid through data recovery to ensure the accuracy of the strata.

[0060] The model is sliced ​​according to the model level, tile size, and grid size defined by the model system, and the model is vectorized to realize a homologous vector-grating integrated model. The final model of this application is obtained based on the obtained homologous vector-grating integrated model.

[0061] 2.2 Model verification:

[0062] After completing data preprocessing and preparing for data extraction and fusion, the data set is checked for consistency and data inconsistency is handled. The consistency check includes: whether the stratification information at the intersection is consistent; whether each matrix layer stratification area has attribute information and color information; whether the color configuration information of areas with the same attributes is consistent. There are inconsistencies in both stratification attributes and matrix layer elevations on both sides of the intersection.

[0063] If the arc attributes on both sides of the same intersection are different, the attribute content needs to be corrected; if the elevations on both sides are inconsistent, the two-dimensional profile data should be reprocessed to determine whether the elevations are the same. If the elevations on both sides are different, the matrix layer elevation correction should be performed. When there is inconsistency between drilling data and data sources such as cross-sections, the data should be adjusted for consistency. The adjustment principle should be based on the basic control framework of borehole and profile data to adjust other data sources. By checking and processing the consistency of the data, it is possible to avoid the offset and distortion of geological interfaces or attributes caused by over-integration of various data in the case of multiple data sources.

[0064] After the three-dimensional model of the surface matrix layer is completed, it is subject to quality inspection and quality evaluation. Quality inspection includes compliance inspection, rationality inspection, accuracy inspection and completeness inspection. Compliance inspection includes modeling task requirements, basic data collation, modeling process methods, and results inspection and acceptance.

[0065] As another embodiment of the present application, establishing a model includes:

[0066] Actual Net Primary Productivity (NPPA) refers to the actual NPP calculated based on remote sensing data or models, which is driven by the combined effects of climate factors and human activities. The CASA model simulates the net primary productivity of regional vegetation based on the integration of various environmental data. The model simulation results have good accuracy, so it is widely used in NPP research. The NPPA used in this paper is calculated using the improved CASA model.

[0067] All data in the datasets are pre-processed by reprojection, mosaicking, clipping, unit conversion and resampling for model calculation and data analysis. The final model of this application is generated after the calculation and data analysis are completed.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
