specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 To illustrate this embodiment, the specific process of a method for evaluating the value of a marsh ecosystem service function in this embodiment is as follows:

[0017] Step 1. Evaluate the carbon sequestration function value of the marsh wetland ecosystem to obtain the carbon sequestration value of the marsh wetland;

[0018] Step 2. Evaluate the value of greenhouse gas emission loss in the swamp wetland ecosystem, and obtain the value of the loss of greenhouse gas emission in the swamp wetland;

[0019] Step 3. Evaluate the water conservation function value of the swamp wetland ecosystem, and obtain the water conservation function value of the swamp wetland;

[0020] Step 4. Evaluate the value of purifying nitrogen and phosphorus in the swamp wetland ecosystem, and obtain the purifying function value of the swamp wetland;

[0021] Step 5. Evaluate the biodiversity maintenance function value of the swamp wetland eco...

specific Embodiment approach 2

[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in Step 1, the carbon sequestration function value evaluation of the swamp wetland ecosystem is carried out; the specific process is:

[0024] V C =(C A +C B +C S )×P C

[0025] In the formula, V C is the carbon sequestration value of swamp wetland, unit is yuan; C A is the amount of aboveground carbon sequestration by swamp wetland plants, unit is ton / year; C B is the amount of carbon sequestered underground by plants in swamp wetlands, unit is ton / year; C S is the carbon storage capacity of swamp wetland soil, unit is ton / year; P C is the carbon sequestration cost, the unit is yuan / ton, 55.98 yuan / ton (2014);

[0026] The amount of aboveground carbon sequestration by swamp wetland plants can be calculated as follows:

[0027] C A =B×C c

[0028] Underground carbon sequestration of marsh wetland plants, the calculation method is:

[0029] C B =B×C c

[0030] In the formula, B...

specific Embodiment approach 3

[0035] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one or two is that in the second step, the evaluation of the value of greenhouse gas emission loss is performed on the swamp wetland ecosystem; the specific process is:

[0036]

[0037] In the formula, V E is the loss value of greenhouse gas emission in marsh wetland, the unit is yuan; for CO 2 Emissions, in tons / year; for CH 4 Emissions, in tons / year; for N 2 O emissions, the unit is tons / year; P c is the cost of carbon sequestration, and the unit is yuan / ton.

[0038] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to a marsh wetland ecosystem service function value evaluation method, aiming to solve the problems that existing marsh wetland ecosystem service functions cannot be monetized precisely and cannot be compared and analyzed under an objective and uniform criterion. The marsh wetland ecosystem service function value evaluation method includes the specific steps of firstly, acquiring marsh wetland carbon sequestration value; secondly, acquiring marsh wetland greenhouse gas emission loss value; thirdly, acquiring marsh wetland water resource conservation function value; fourthly, acquiring marsh wetland purifying function value; fifthly, evaluating biodiversity maintenance function value of a marsh wetland ecosystem so as to obtain marsh wetland biodiversity maintenance function value; sixthly, summing up the value from the first step to the fifth step under the uniform criterion in the same year so as to obtain a total value quantity of the marsh wetland ecosystem service functions. The marsh wetland ecosystem service function value evaluation method is used for the field of evaluation of the marsh wetland ecosystem service functions.

Description

technical field [0001] The invention relates to a method for evaluating the value of the service function of the swamp wetland ecosystem. Background technique [0002] To some extent, the ecosystem service function can measure the ecological environment quality of the region, provide scientific basis for environmental protection and ecological construction, and is the material basis for human survival. However, in the process of human utilization and transformation of nature, often only focus The direct consumption value of natural resources, while ignoring the ecological service function value of the ecosystem. [0003] Habitat Evaluation Procedures (Habitat Evaluation Procedures) is one of the relatively complete evaluation procedures in the early stage, but it does not consider the satisfaction of human needs by natural habitats. After the proposal of HEP, many wetland evaluation methods have been developed: HAT (Habitat Assessment Technique), WET (The Wetland Evaluation...
