Determine the type and boundary of ecosystem: According to the type and boundary of ecosystem, determine the calculation range of GEP. This needs to consider the regional characteristics of ecosystem, ecological environment and other factors.
Investigate the characteristics of ecosystem: collect basic information and data of ecosystem, including biomass, productivity, species diversity, soil quality, etc. These data can be obtained through field investigation, remote sensing monitoring and literature.
Estimate the value of ecosystem service products: according to the characteristics and types of ecosystems, estimate the value of various ecosystem service products provided by ecosystems, including material products and ecological adjustment service products. For example, the material products provided by forest ecosystem include wood, fruit and so on. Ecological regulation service products include air purification and water resources protection.
Calculation of GEP: Calculate the value of various ecological service products provided by the ecosystem comprehensively, and get the total productivity of the ecosystem. GEP can be calculated by direct market method, alternative market method, simulated market method and other economic evaluation methods, and the value of ecological service products can be quantified as monetary value.
The influence of GEP accounting method on human beings;
1. Promote ecological protection: GEP accounting method can quantify the value of ecological services provided by ecosystems and make people more intuitively realize the importance of natural ecology. This will help to raise people's awareness of ecological protection and promote ecological protection actions.
2. Optimize resource allocation: Through GEP accounting, we can know the value of different ecosystem services, so as to better optimize resource allocation. For example, the forest ecosystem in a certain area is of high value, so it is necessary to give priority to protecting this forest.
3. Promote the development of green economy: GEP accounting method can transform the value of ecological services into economic value and provide data support for the development of green economy. This will help to promote the development of eco-friendly industries and promote the green transformation of the economy.
4. Strengthen the basis for decision-making: When the government formulates relevant policies, it can understand the value of the ecosystem through GEP accounting method and formulate more scientific and reasonable policies. For example, the government can formulate relevant policies to protect those ecosystems with high ecological value.
5. Improve the quality of life: various ecological services provided by the ecosystem, such as air purification and climate regulation, are closely related to people's quality of life. GEP accounting method can help people better understand the value of these services, thus improving the quality of life.
