Description

Technical Field

[0001] This invention relates to the field of interspecific relationship analysis of trees, and particularly to a method, apparatus, device, and storage medium for analyzing interspecific relationships of trees. Background Technology

[0002] Interspecific relationship analysis, based on factors such as spatial occupancy, homospecific density, and the richness and size of neighboring species, analyzes the interactions between species. It is an essential factor in assessing species growth and survival and has long been valued by ecologists. Interspecific relationships mainly include competitive and mutually beneficial interactions between neighboring individuals and target individuals, also known as "neighborhood interactions."

[0003] Currently, a common method for analyzing interspecific relationships is to use competition index models to calculate competition indices. Taking trees in a forest ecosystem as an example, the competition index is calculated based on the size and number of trees in a given neighborhood to describe the neighbor effect within the neighborhood. However, the competition index model often treats trees of different types in the neighborhood as the same type, thus ignoring the differences in the influence of non-target trees of different types on the target tree, making it difficult to accurately analyze the interspecific relationships between different tree types. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a method, apparatus, device, and storage medium for analyzing interspecific relationships of trees. By combining tree type data of target trees and non-target trees, and based on tree growth data and functional trait data, the interspecific relationships of target trees and non-target trees are analyzed.

[0027] Please see Figure 1 , Figure 1 The flowchart illustrates a method for analyzing interspecific relationships of trees according to an embodiment of this application. The method includes the following steps:

[0028] S1: Obtain tree growth data and functional trait data for each tree in the target area.

[0029] The execution subject of the interspecific relationship analysis method of trees is the analysis device for the interspecific relationship analysis method of trees (hereinafter referred to as the analysis device). In an optional embodiment, the analysis device can be a computer device, a server, or a server cluster composed of multiple computer devices.

[0030] In one optional embodiment, the target area is located in Jiaohe City, Jilin Province, belonging to the Zhangguangcai Mountains of the Changbai Mountain Range. The forest type is primary Korean pine broad-leaved forest, with an altitude of 689 meters and a geographical coordinate of E127°45′36.91″, 43°58′05.60″. The climate is a temperate continental climate significantly influenced by temperate monsoons, with an average annual temperature of 3.7℃. The highest annual temperature occurs in July at 21.7℃, and the lowest temperature occurs in January at -18.6℃. The average annual precipitation is 696.9 mm. The soil type in the study area is dark brown forest soil, with a thickness of 0.2-1 m and an average depth of 0.45 m. The forest vegetation belongs to the Northeast China Changbai Mountain Flora of the Sino-Japanese Forest Plant Subregion, with approximately 923 plant species belonging to 108 families. The vegetation type is mainly primary broad-leaved Korean pine forest and its secondary forest, including several different tree types, such as Korean pine, sand pine, walnut, Manchurian ash, split-leaved elm, Amur cork tree, purple linden, privet, maple, and birch, etc.

[0031] The tree growth data reflects the current growth status of the tree, and includes tree diameter at breast height (DBH) data and tree height at breast height sectional area data.

[0032] Functional traits refer to a series of plant attributes that have a potentially significant impact on plant establishment, survival, and growth. The functional trait data are data obtained by sampling various plant attributes of trees. The functional trait data include leaf area ratio data, leaf area data, leaf nitrogen content data, leaf carbon content data, carbon-nitrogen ratio data, and tree height data.

[0033] In this embodiment, the analysis device can acquire tree growth data and functional trait data of each tree in the target area input by the user, or it can download data from a preset database.

[0034] S2: Obtain the target tree and several non-target trees from the trees, and obtain the tree type data of the target tree and the non-target trees.

[0035] The target tree is a tree selected from the trees in the target area; the non-target tree is a tree selected outside the target tree within a sample circle drawn with the target tree as the center and a preset radius data.

[0036] In this embodiment, the analysis device selects healthy target species trees without obvious diseases or pests from the trees as target trees, and draws a sample circle area with the target tree as the center and a radius of 10m away from the target tree. Other trees within the sample circle area are regarded as non-target trees. At the same time, the tree type data of the target tree and the non-target trees are obtained.

[0037] S3: Based on the tree type data, tree growth data, functional trait data of the target tree and several non-target trees, and the preset interspecific relationship parameter calculation module, obtain the interspecific relationship parameters between the target tree and each non-target tree.

[0038] Interspecific relationships include competitive and mutually beneficial relationships, and the interspecific relationship parameters are used to reflect the competitive and mutually beneficial effects between the target tree and non-target trees.

[0039] In this embodiment, the analysis device obtains the interspecific relationship parameters between the target tree and each non-target tree based on the tree type data, tree growth data, functional trait data of the target tree and several non-target trees, as well as the preset interspecific relationship parameter calculation module.

[0040] Please see Figure 2 , Figure 2 The flowchart of step S3 in the tree interspecific relationship analysis method provided in one embodiment of this application includes steps S301 to S302, as follows:

[0041] S301: Obtain environmental factors associated with the tree type data of the target tree.

[0042] In this embodiment, the analysis device obtains the environmental factors associated with the tree type data of the target tree from a preset mapping table of tree types and environmental factors, based on the tree type data of the target tree.

[0043] S302: Based on the environmental factors, the tree growth data and functional trait data of the target tree and non-target trees are respectively input into the interspecific relationship parameter calculation module, and the interspecific relationship parameters between the target tree and each non-target tree are obtained according to the preset interspecific relationship parameter calculation algorithm.

[0044] The algorithm for calculating the interspecific relationship parameters is as follows:

[0045]

[0046] In the formula, Gi E represents the growth of the vertical area at breast height (BH5) in the tree growth data of the i-th target tree. i For the environmental factors corresponding to the tree type data of the preset i-th target tree, G max D represents the maximum basal area growth at breast height of the target tree. i C represents the diameter at breast height (DBH) of the i-th target tree; i,j Let x be the interspecific relationship parameter. i Let x be the functional trait data of the i-th target tree. j Let sgn() be the functional trait data of the j-th non-target tree, and sgn() be the symbolic function.

[0047] In this embodiment, the analysis device inputs the tree growth data and functional trait data of the target tree and non-target trees into the interspecific relationship parameter calculation module based on the environmental factors to obtain the interspecific relationship parameters between the target tree and each non-target tree.

[0048] Specifically, the interspecific relationship parameters include a first relationship parameter, a second relationship parameter, a third relationship parameter, a fourth relationship parameter, and a tolerance parameter, and the expressions for the interspecific relationship parameters are as follows:

[0049] C i,j =C1+C2-C x +C3+C4

[0050] In the formula, C1 is the first relation parameter, C2 is the second relation parameter, C3 is the third relation parameter, C4 is the fourth relation parameter, and C... x This is a tolerance parameter. It avoids the drawback of ignoring the differences in the impact of different tree types, and more accurately obtains the interspecific relationship parameters between the target tree and various non-target trees.

[0051] S4: Based on the interspecific relationship parameters, functional trait data, and the preset interspecific relationship analysis module, obtain the interspecific relationship analysis results between the target tree and each non-target tree.

[0052] The interspecific relationship analysis results include intraspecific and extraspecific types of interspecific relationship analysis results. In order to better analyze the interspecific relationship analysis results between the target tree and each non-target tree, in this embodiment, the analysis device obtains the interspecific relationship analysis results between the target tree and each non-target tree based on the interspecific relationship parameters, functional trait data and preset interspecific relationship analysis modules.

[0053] Please see Figure 3 , Figure 3 The flowchart of S4 in the tree interspecific relationship analysis method provided in one embodiment of this application is as follows: S401 to S402 are detailed below:

[0054] S401: Input the interspecific relationship parameters and functional trait data into the interspecific relationship analysis module, and obtain the corresponding competition parameters for each interspecific relationship parameter according to the preset competition parameter calculation algorithm.

[0055] The algorithm for calculating the competition parameters is as follows:

[0056] C1 = C intra,i α

[0057] C2 = C inter,i (1-α)

[0058] C x =C t x i

[0059] C3 = C e x j,tot

[0060] C4 = C d |x j -x i |

[0061] In the formula, C intra,i The first competition parameter represents the intra-neighbor effect experienced by the i-th target tree relative to non-target trees; C inter,i The second competition parameter represents the extraspecific neighbor effect experienced by the i-th target tree relative to the non-target tree. α is the tree type identifier; when the target tree and the non-target tree have the same tree type, α is 0; when the target tree and the non-target tree have different tree types, α is 1. t The third competition parameter, x, represents the target tree's resilience to competition relative to non-target trees. i C represents the functional trait data corresponding to the i-th target tree; e The fourth competition parameter, x, represents the trait effect of the target tree relative to the non-target trees. j,tot This is the accumulated data for the functional traits of all non-target trees surrounding the i-th target tree; C d The fifth competition parameter represents the effect of trait differences between the target tree and non-target trees, |x j -x i | represents the absolute distance data of traits between the i-th target tree and the j-th non-target tree;

[0062] In this embodiment, the analysis device inputs the interspecific relationship parameters and functional trait data into the interspecific relationship analysis module. Based on a preset competition parameter calculation algorithm, it obtains the corresponding competition parameters for each interspecific relationship parameter. Specifically, based on leaf nitrogen content data, x... iLet x be the leaf nitrogen content data corresponding to the i-th target tree. j When the leaf area ratio data corresponding to the j-th non-target tree is given, C is calculated. d,氮 Based on tree height data, x j,tot When accumulating the tree height data of all non-target trees surrounding the i-th target tree, C is calculated. e,树高 .

[0063] S402: Based on the competition parameters corresponding to each interspecific relationship parameter and the preset competition parameter threshold, obtain the interspecific relationship analysis results between the target tree and each non-target tree.

[0064] The analysis device compares the corresponding competition parameters of each interspecific relationship parameter with the corresponding competition parameter threshold. When the competition parameter is greater than the competition parameter threshold, the interspecific relationship between the target tree and the non-target tree is set as a competitive relationship. When the competition parameter is less than the competition parameter threshold, the interspecific relationship between the target tree and the non-target tree is set as a mutually beneficial relationship, and the interspecific relationship analysis results are obtained.

[0065] In an optional embodiment, all the competition parameter thresholds are set to 0. Specifically, when the first competition parameter C... intra,i >0, the interspecific relationship analysis result between the target tree and the non-target tree is the result of the competition relationship analysis of the extraspecific type, when the second competition parameter C inter,i >0, the interspecific relationship analysis results between the target tree and non-target trees are the intraspecific type competition relationship analysis results;

[0066] When the third competition parameter C e,树高 >0 indicates a competitive relationship between the target tree and non-target trees based on tree height data;

[0067] When the fourth competition parameter C d,氮 If the result is >0, the interspecific relationship analysis between the target tree and non-target trees based on the leaf nitrogen content data is a competition relationship analysis result.

[0068] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a tree interspecific relationship analysis device according to an embodiment of this application. The device can be implemented entirely or partially through software, hardware, or a combination of both. The device 4 includes:

[0069] The first acquisition module 41 is used to acquire tree growth data and functional trait data of each tree in the target area, wherein the tree growth data includes tree diameter at breast height (DBH) data and tree height at breast height (DBH) sectional area data.

[0070] The second acquisition module 42 is used to acquire a target tree and several non-target trees from the trees, and to acquire tree type data of the target tree and the non-target trees; the target tree is a tree selected from the trees in the target area; the non-target tree is a tree selected outside the target tree within the sample circle area drawn with the target tree as the center and a preset radius data.

[0071] The interspecific relationship parameter calculation module 43 is used to obtain the interspecific relationship parameters between the target tree and each non-target tree based on the tree type data, tree growth data, functional trait data of the target tree and several non-target trees, as well as the preset interspecific relationship parameter calculation module.

[0072] The analysis module is used to obtain the interspecific relationship analysis results between the target tree and each non-target tree based on the interspecific relationship parameters, functional trait data and the preset interspecific relationship analysis module.

[0073] In this embodiment, a first acquisition module acquires tree growth data and functional trait data of each tree in the target area, wherein the tree growth data includes tree diameter at breast height (DBH) data and tree height at breast height sectional area data; a second acquisition module acquires a target tree and several non-target trees from the trees, and acquires tree type data of the target tree and the non-target trees; the target tree is a tree selected from the trees in the target area; the non-target trees are trees selected outside the target tree within a sample circle drawn with the target tree as the center and a preset radius data; an interspecific relationship parameter calculation module acquires interspecific relationship parameters between the target tree and each non-target tree based on the tree type data, tree growth data, functional trait data of the target tree and several non-target trees, and a preset interspecific relationship parameter calculation module; an analysis module acquires the interspecific relationship analysis results between the target tree and each non-target tree based on the interspecific relationship parameters, functional trait data, and a preset interspecific relationship analysis module. By combining tree type data of target trees and non-target trees, and based on tree growth data and functional trait data, the interspecific relationships of target trees and non-target trees are analyzed. This avoids the shortcoming of ignoring the differences in the impact of different tree types and provides a more accurate analysis of the interspecific relationships between trees of different types.
