[0060] Step 101, establishing a wetland multifunctional partition comprehensive index system framework, and obtaining multi-period data; taking the multi-period data as input data, a wetland multifunctional comprehensive partition index method is constructed.

[0061] In the above step 101, the present application constructs a wetland multifunctional comprehensive partition index system by establishing a wetland multifunctional partition comprehensive index system framework, and determines the ecological function index system and the management function index system of different wetland types.

[0062] Using the wetland multifunctional comprehensive partition index system framework, the target layer, the criterion layer and the index layer of the wetland multifunctional comprehensive partition index system are established. The target layer is the wetland multifunctional comprehensive partition index system; the criterion layer includes the wetland ecological function partition index system and the wetland management function partition index system; the index layer is that the wetland ecological function partition index system includes biological and raw material production, air and water regulation, waste treatment, soil conservation, maintenance of biological diversity and provision of landscape aesthetics; the wetland management function partition index system includes climate, terrain, wetland type, vegetation coverage, soil type, social economy, land use and government planning.

[0063] Using the established wetland multifunctional comprehensive partition index system, multi-period data is collected. The multi-period data includes wetland classification data, climate data, terrain data, vegetation data, soil data, social economic data and wetland ecological function data in multiple periods.

[0064] ​Optionally, the method for constructing the wetland multifunctional comprehensive zoning index in step 101 takes multi-period data as input data, and comprises steps A1 to A2.

[0065] Step A1: establishing a multi-period wetland multifunctional comprehensive zoning data set according to multi-period data; wherein the multi-period wetland multifunctional comprehensive zoning data set comprises wetland ecological dominant function data of a plurality of specified years and wetland management function data of a plurality of specified years.

[0066] Step A2: determining a specified year as a first specified year; and calculating a wetland multifunctional comprehensive zoning index of the first specified year by a first preset function according to a wetland ecological dominant function zoning index of the first specified year and a wetland management function index of the first specified year.

[0067] In the above steps A1 to A2, the method for constructing the urban agglomeration wetland multifunctional comprehensive zoning index is established by using the established multi-period wetland multifunctional comprehensive zoning data set. The specified year is any year or a year set according to needs.

[0068] The wetland multifunctional comprehensive zoning index is calculated by the following formula (1):

[0069] (1)

[0070] In the formula, W represents the wetland function zoning index of a certain year, E represents the wetland ecological dominant function zoning index of a certain year, and T represents the wetland management function index of a certain year.

[0071] Step 102: calculating the wetland ecological dominant function index according to the multi-period data and the wetland multifunctional comprehensive zoning index method.

[0072] In the above step 102, the multi-period wetland type data and the wetland ecological function data are collected to generate the initial value of each ecological function of each wetland type, such as rivers, inland beaches, mangroves, coastal beaches, shallow sea areas, reservoirs and breeding ponds.

[0073] The initial value of each ecological function of each wetland type is calculated to generate a unit quantity of each ecological function of each wetland type.

[0074] The unit quantity of each ecological function of each wetland type is multiplied by the area of the wetland type to obtain the single ecological function value of a single wetland type and the total ecological function value of the wetland.

[0075] By using the wetland multifunctional integrated zoning index method and the single ecological function values ​​of a single wetland type and the total ecological function values ​​of wetlands in multiple periods, the ratio of single ecological function to total ecological function of wetlands is calculated, generating wetland ecological dominant function indices for different wetland types, regions, periods and functions.

[0076] Optionally, step 102, which calculates the dominant ecological function index of wetlands based on multi-period data and the comprehensive wetland multifunctional zoning index, includes steps B1 to B4:

[0077] Step B1: Calculate the initial values ​​of each ecological function for multiple wetland types in multiple periods based on multi-period data; where multiple wetland types include: rivers, inland beaches, mangroves, coastal mudflats, shallow sea areas, reservoirs, and aquaculture ponds;

[0078] Step B2: Calculate and generate multiple ecological function units for any ecological function of any wetland type at any time based on multiple initial values ​​of ecological functions for multiple periods and multiple wetland types;

[0079] Step B3: Calculate the multi-period ecological function value by multiplying the unit quantity of any ecological function of any wetland type in any period by the wetland area corresponding to the wetland type; wherein, the multi-period ecological function value includes the single ecological function value of a single wetland type in multiple periods and the total ecological function value of wetlands in multiple periods.

[0080] Step B4: Calculate the dominant ecological function index of any wetland type, any region, any period, and any function based on the wetland multifunctional integrated zoning index method and multi-period ecological function values.

[0081] The dominant ecological function index of wetlands in multiple periods is calculated using the following formula:

[0082] (2)

[0083] In the formula, E represents the wetland ecological dominant function index for a certain year; c i It is the first i Unit quantity of ecological function of wetland type; c j It is the first j Ecological function unit quantity; q i,j This is a table of wetland ecological function indicators; z i It is the first i Area of ​​wetlands; i It is a wetland type. j It is an ecological function. q i,j , c i ,c j The calculation is made by formula (3) to formula (5) respectively.

[0090] The relative importance of all indicators of the wetland management function is empirically weighted and sequenced using the wetland management function index and the collected data. The wetland management function index matrix and the wetland management function index standardized characteristic vector are input to generate the wetland management function empirical weight sequence.

[0091] The relative importance of all indicators of the wetland management function is numerically weighted and sequenced using the wetland management function index and the collected data. The wetland management function index standardized value is input to calculate the difference coefficient of each indicator, and the wetland management function numerical weight sequence is generated.

[0092] The wetland management function index comprehensive weight sequence is generated using the wetland management function empirical weight sequence and the wetland management function numerical weight sequence.

[0093] The wetland management function index in each period is calculated by adding the comprehensive weight of each indicator of the wetland management function using the wetland multi-function comprehensive zoning index method, the standardized value of each wetland management function index in each period, and the wetland management function index comprehensive weight sequence.

[0094] Optionally, the step 103 of calculating the wetland management function index according to the multi-period data and the wetland multi-function comprehensive zoning index method includes steps C1 to C4:

[0099] The wetland management and cultivation function index is calculated by formula (6):

[0100] (6)

[0101] In the formula, T denotes the wetland management and cultivation function index in a certain year; m is the empirical weight of the i-th wetland management and cultivation function index; i is the numerical weight of the i-th wetland management and cultivation function index; n is the i-th wetland management and cultivation function index standardization value. i u i (7)

[0102] (8)

[0103] (9)

[0104] (9)

[0105] In the formula, b is the wetland management and cultivation function index judgment matrix; k i is the normalized characteristic vector of the i-th wetland management and cultivation function index; i i is the difference coefficient of the i-th wetland management and cultivation function index. h i Step 104: determining the partition rules and the partition levels according to the calculation results of the wetland ecological dominant function index and the wetland management and cultivation function index respectively; and determining the wetland multi-function comprehensive partition results according to the partition rules and the partition levels.

[0108] The wetland pipe breeding function zoning grade is determined by using the multi-period wetland pipe breeding function index by using the natural breakpoint method.

[0109] According to the wetland dominant function zoning grade rule and the wetland pipe breeding function zoning grade determination, the wetland dominant function zoning result and the wetland pipe breeding function zoning result are respectively divided.

[0110] The wetland dominant multi-period ecological function zoning result and the multi-period wetland pipe breeding function zoning result are taken as input data to construct a multi-period wetland multi-function comprehensive zoning GIS spatial overlay calculation method.

[0115] Step D4: The wetland multi-function comprehensive zoning is determined according to the wetland dominant function zoning result and the wetland pipe breeding function zoning result.

[0117] (10)

[0118] In the formula, W l is the wetland multi-function comprehensive zoning result; E l is the wetland dominant function zoning result; T l is the wetland pipe breeding function zoning result.

The application considers the influence of the surrounding environment on the wetland type in the wetland management and conservation function partition, and can obtain the management form of different wetlands from the management and conservation angle through various type indexes.
