Embodiment 1
[0057] A kind of urban ecological planning zoning method, with reference to figure 1 , including step S101 to step S105.
[0058] Step S101: Obtain the plant type in the target area, and call an evaluation model suitable for the plant type.
[0059] The acquisition method is to provide users with plant types to choose from, select the plant types in the target area, and then obtain the user's selection results, and the plant types include trees, shrubs and herbaceous plants. Each plant type has a specific evaluation model that is adapted to the plant type, for example, the evaluation model for trees is
[0060] Ga arbor = , where DBH is the diameter at breast height, and the calculation formula is
[0061] . where t is the age of the tree.
[0062] The evaluation model for shrubs is
[0063] Ga shrub = aH-b. where H is the plant height.
[0064] The evaluation model for herbaceous plants is
[0065] Ga herb=LAI*S, where LAI=1.6.
[0066] Above, a1, a2, a3, b1, b2,...
Embodiment 2
[0076] An urban ecological planning zoning system, referring to figure 2 , including a processor and a memory, and the memory stores an instruction set for the processor to call to realize the following functions:
[0077] Obtain the plant type in the target area, and call the evaluation model suitable for the plant type;
[0078] Obtain the parameter values of each evaluation item of the evaluation model;
[0079] Calculate the evaluation value according to the evaluation model and the obtained parameter values;
[0080] Based on the calculated evaluation value of each plant type, the total evaluation score is calculated according to the total evaluation model;
[0081] Ecological divisions are divided according to the total score of the assessment.
[0082] Plant types include trees, shrubs, and herbs.
[0083] The evaluation model for the arbor is configured as
[0084] Ga arbor = ;
[0085] The evaluation model for shrubs is
[0086] Ga shrub = aH - b;
[0087...
