Forest ecosystem service function assessment specification
1 Scope
This standard specifies the data sources, evaluation index systems, and evaluation formulas for forest ecosystem service function assessment.
This standard applies to the assessment of the main ecological service functions of forest ecosystems within the People's Republic of China, but does not involve forest resources.
Source value, forest by-products and forest land's own value.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
The natural environmental conditions and effects that human beings depend on for the formation and maintenance of forest ecosystems and ecological processes. Mainly including forests in
Water conservation, soil conservation, carbon sequestration, accumulation of nutrients, purification of the atmosphere, forest protection, biodiversity conservation and forest recreation
The ecological service functions provided by the parties.
2.2
Long-term continuous positioning observation data of forest ecosystems, forest resource inventory data and social public data for forest ecosystem services
The evaluation of the physical quantity and value of the function.
2.3
The interception, absorption and storage of precipitation by forests converts surface water into surface runoff or groundwater. The main function is in the increase
Use water resources, purify water quality and regulate runoff.
2.4
The layers of living habitats and litter in the forest intercept the precipitation, reducing the impact of water droplets on the topsoil and the erosion of surface runoff;
The roots hold the soil, prevent soil collapse and slip, reduce soil fertility loss and improve soil structure.
2.5
Forest ecosystems function to fix carbon and release oxygen through forest vegetation, soil animals and microorganisms.
2.6
Forest plants absorb nitrogen, phosphorus, potassium and other nutrients in the atmosphere, soil and precipitation through biochemical reactions and store them in various organs in the body.
can. The accumulation of nutrient functions in forest vegetation plays an important role in reducing downstream non-point source pollution and water eutrophication.
2.7
Forest ecosystems absorb, filter, block and block atmospheric pollutants such as sulfur dioxide, fluoride, nitrogen oxides, dust, heavy metals, etc.
Decomposes, as well as reduces noise, provides functions such as negative ions and terpenes (such as fentanyl).
2.8
Protective forests such as wind-fixing sand forest, farmland pasture shelter forest, revetment forest, and road protection forest reduce wind, sand, drought, flood, typhoon, saline, frost, sand
