BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a system principle block diagram of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Example 1, please refer to Figure 1, this application provides a landscape design and landscaping assistance system based on BIM technology, including a garden information acquisition module, a garden area analysis module, an adaptive analysis and processing module, and a landscaping design information output module. At the same time, it is comprehensively attached Figure 1 It can be known that the above corresponding functional modules are connected by one-way electrical connection.

[0040] Garden information acquisition module, which is used to acquire the garden information of the target garden. Specifically, the target garden refers to the garden that needs to be designed and landscaped, which is set by the operator himself and output to the system. And the acquisition of garden information is directly obtained through the corresponding BIM technology. Among them, the garden information is mainly terrain data, specifically the slope and height difference data corresponding to the garden. Then, the acquired garden information is transmitted to the garden area analysis module.

[0041] Garden area analysis module, which is used to divide the target garden into areas according to the garden information. When dividing the areas, it is divided according to the spatial layout corresponding to the target garden, and multiple functional areas are obtained. At the same time, they are numbered as i, and i = 1, 2,..., j, where j represents the number of functional areas. Then, one group of functional areas is used as the analysis object for analysis;

[0042] Obtain the area information of the analysis object, and at the same time obtain all landscaping methods. Here, the landscaping method means making corresponding layout designs according to the regional characteristics artificially, and is numbered as a, and a = 1, 2,..., b, where b represents the number corresponding to the landscaping method. Then, calculate the matching value between the analysis object and the landscaping method from two aspects of functional adaptability and ecological rationality; and the analysis here is based on the design requirements corresponding to different landscaping methods.

[0043] The specific method for analyzing functional adaptability is: by evaluating and assigning scores to ecological diversity and functional ornamental value respectively, obtaining the ecological diversity value and the functional ornamental value;

[0044] Among them, the specific method for evaluating and assigning scores to ecological diversity is to obtain the number of plant species in the analysis object, and at the same time quantify the number of plant species and determine the scoring range. Here, the scoring range can be set as 0 - 10 points. Then, score based on the plant species, and record the obtained score as the assignment to obtain the ecological diversity value. For example, when the number of plant species is 10 or less, the corresponding score is 1 point; 11 - 20 species correspond to 5 points; 21 - 30 species correspond to 7 points; 31 species and above correspond to 10 points. And if the number of plant species obtained in the analysis object is 26, the corresponding assignment is 7;

[0045] The specific method for evaluating and assigning scores to functional aesthetics is to obtain the types and quantities of all landscape elements within the analysis object, perform corresponding scoring processing based on the types of landscape elements, and simultaneously obtain the corresponding scores and record them as assignments to obtain the corresponding functional aesthetic values. For example, when the number of landscape element types is 5 or less, the corresponding score is 1 point, indicating that the landscape elements are relatively single and the functional aesthetics is low; 6 - 10 types correspond to 5 points, indicating that the landscape elements have a certain richness and can provide a certain degree of viewing experience and functions; 11 - 15 types correspond to 7 points, indicating that the landscape elements are rich and can better meet the viewing and functional requirements; 16 types and above correspond to 10 points, meaning that the landscape elements are extremely rich and the functional aesthetics is extremely high.

[0046] The obtained ecological diversity value and functional aesthetic value are comprehensively calculated. According to the formula functional adaptation value = ecological diversity value × ecological diversity weight + functional aesthetic value × functional aesthetic weight, the functional adaptation value is calculated, and the specific values of the ecological diversity weight and functional aesthetic weight are set by the operator.

[0047] The specific method for analyzing ecological rationality is to obtain the vegetation diversity value and ecological utilization value by evaluating and assigning scores from two aspects: vegetation diversity and ecological utilization.

[0048] Among them, the specific method for evaluating and assigning scores to vegetation diversity is to obtain the matching vegetation types corresponding to the analysis object, and the matching vegetation types here refer to the types of native plants widely used in landscaping. At the same time, calculate the proportion of the quantity corresponding to the matching vegetation types, and perform corresponding evaluation and scoring based on the proportion. The obtained score is used as the assignment to obtain the vegetation diversity value. Specifically, as follows, when the proportion is 30% or less, the score is 1 point, indicating that the proportion of native plants is relatively low and the vegetation diversity is poor; when the proportion is 31% - 50%, the score is 3 points, meaning that the vegetation diversity is at a medium level; when the proportion is 51% - 70%, the score is 7 points, indicating that the proportion of native plants is relatively high and the vegetation diversity is good; when the proportion is 71% and above, the score is 10 points, representing that the vegetation diversity is very excellent.

[0049] The specific way to evaluate and score the ecological utilization value is to analyze the carbon sink capacity corresponding to the analysis object and calculate the corresponding carbon sink amount. The calculation of the carbon sink amount here can be calculated by the aboveground biomass method. Specifically, the carbon sink capacity is estimated by measuring the biomass of the aboveground part of the grassland, because the carbon storage of grassland is mainly concentrated in the aboveground part. Generally speaking, the carbon content of the aboveground biomass of grassland is about 40%-45%. Assuming that in a 1 square meter sample plot, the dried aboveground biomass is 200 grams, calculated at a carbon content of 42%, the carbon storage of 1 square meter of grassland is 84 grams. If the total area of ​​grassland is 500 hectares (5,000,000 square meters), the total carbon sink of the grassland is 420 tons. At the same time, the obtained carbon sink is evaluated and scored, and the obtained score is recorded as the assigned value to obtain the ecological utilization value. When the carbon sink is lower than 40% of the regional average level, it indicates that the carbon sink capacity of the ecosystem is poor, and the corresponding value is 1 point. If the carbon sink is in the region If the carbon sequestration amount is between 40% and 70% of the regional average level, it indicates that the carbon sequestration capacity is at an average level, corresponding to 3 points. If the carbon sequestration amount is between 70% and 100% of the regional average level, it indicates that the ecosystem carbon sequestration is in a good state, corresponding to 5 points. When the carbon sequestration amount is between 100% and 150% of the regional average level, it indicates that the ecosystem carbon sequestration capacity is excellent, corresponding to 7 points. If the carbon sequestration amount reaches or exceeds 150% of the regional average level, it indicates that the ecosystem has excellent performance in carbon sequestration, corresponding to 10 points.

[0050] The obtained vegetation diversity value and ecological utilization value are calculated comprehensively, and the ecological reasonable value is calculated according to the formula: ecological reasonable value = vegetation diversity value × vegetation diversity weight + ecological utilization value × ecological utilization weight, where the specific values ​​of vegetation diversity weight and ecological utilization weight are set by the operator;

[0051] The obtained functional fitness value and ecological rationality value are transmitted to the adaptive analysis and processing module.

[0052] Adaptive analysis and processing module, which is used to calculate the matching value between the analysis object and the landscaping method according to the obtained functional fitness value and ecological rationality value. According to the formula matching value = functional fitness value × y1 + ecological rationality value × y2, the matching value corresponding to the analysis object is calculated, wherein y1 and y2 are corresponding weight coefficients, and the specific values ​​are set by the operator. Similarly, the matching value corresponding to the analysis object and all landscaping methods n is calculated and recorded as Pa. At the same time, all functional areas i are processed in the same way, and the corresponding matching values ​​are calculated. At the same time, they are sorted from large to small according to the matching value Pa, and the landscaping method with the largest matching value is selected as the pre-selected method;

[0053] Obtain the preselected landscaping methods corresponding to all functional areas, and determine whether there are identical preselected landscaping methods. If there are identical cases, generate an identical analysis signal. Conversely, if there are no identical cases, generate corresponding design information based on the generated preselected landscaping methods, and transmit the design information to the landscaping design information output module;

[0054] Then process the obtained identical analysis signal, obtain the functional areas corresponding to the identical preselected landscaping methods, and record them as the areas to be analyzed. Then obtain the matching values between the areas to be analyzed and the preselected landscaping methods, compare the magnitudes of the matching values at the same time, and obtain the standard area based on the area to be analyzed with the largest matching value. Match the corresponding preselected landscaping method with the standard area to generate design information, and transmit the design information to the landscaping design information output module at the same time. Further analyze the remaining areas to be analyzed;

[0055] Obtain the landscaping methods corresponding to the areas to be analyzed, and here they are the remaining areas to be analyzed. At the same time, select the largest matching value among the remaining landscaping methods, and generate design information based on the landscaping method corresponding to the largest matching value, and transmit the design information to the landscaping design information output module. Specifically, if there are still identical cases here, screen according to the magnitudes of the matching values, and perform the same operations by analogy.

[0056] The landscaping design information output module is used to display the generated design information to the corresponding operators.

[0057] Embodiment 2. This embodiment is implemented on the basis of Embodiment 1, and the differences from Embodiment 1 are as follows:

[0058] When calculating the carbon sequestration amount in this application, the carbon storage assessment method is used for analysis. Specifically, the carbon storage of wetland plants and soil is measured separately to calculate the total carbon sequestration capacity. For wetland plants, the plant biomass is measured by using a method similar to the forest biomass method or the grassland aboveground biomass method, and then the plant carbon storage is calculated according to the plant carbon content. For wetland soil, soil samples at different depths are collected, the soil organic carbon content is measured, and multiplied by the soil volume to obtain the soil carbon storage. Finally, the plant carbon storage and the soil carbon storage are added together to obtain the total carbon sequestration amount of the wetland. For example, the plant carbon storage of a certain wetland is 50 tons / ha, the soil organic carbon content is 2%, the soil bulk density is 1.2 g / cm³, and the average depth is 1 m. After calculation, the soil carbon storage is 240 tons / ha, then the total carbon sequestration amount of this wetland is 290 tons / ha.

[0059] Embodiment 3. This embodiment is implemented on the basis of Embodiment 1, and the differences from Embodiment 1 and Embodiment 2 are as follows:

[0060] When calculating the carbon sink volume itself, it is analyzed and calculated by the biomass method. Specifically, the biomass of various parts such as arbors, shrubs, and herbs in the forest is measured, and then according to the conversion relationship between biomass and carbon storage, the carbon sink capacity of the forest is calculated. First, methods such as the standard tree method and the plot method are used to measure the diameter at breast height and tree height of different tree species in the forest, and the biomass of a single tree is calculated using the biomass equation, and then the stand biomass is obtained by summing up. Then, according to the average conversion coefficient of forest biomass and carbon content (generally taking 0.45 - 0.5), the biomass is converted into carbon storage. Finally, the carbon sink volume per unit area is calculated according to the forest area. Suppose a forest area is 100 hectares, the total biomass measured and calculated is 5000 tons, and calculated according to the conversion coefficient of 0.48, the carbon storage is 2400 tons, and the carbon sink volume per unit area is 24 tons / hectare.

[0061] Example 4, as the fourth example of the present invention, focuses on combining the implementation processes of Example 1, Example 2, and Example 3.

[0062] Some of the data in the above formula are taken for numerical calculation without substituting parameter units for calculation. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0063] The above examples are only used to illustrate the technical methods of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred examples, those of ordinary skill in the art should understand that the technical methods of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical methods of the present invention.
