Regulation procedure for ecological benefit of shelter forest system
1 Scope
This standard specifies the index system for ecological benefit evaluation of shelter forest system, the calculation method of ecological benefit comprehensive index and evaluation grading
Method and ecological benefit evaluation process of shelter forest system.
This standard applies to the evaluation of the ecological benefits of the construction of the shelterbelt system within the territory of the People's Republic of China, but does not involve the value of forest resources,
Forest by-products and the value of woodland itself.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Protective forest protectiveforest
In order to maintain water and soil, prevent wind and sand, conserve water, regulate climate, reduce pollution, and improve ecological environment and human production and living conditions.
Natural forests and plantations. According to its purpose and effectiveness, it can be divided into water conservation forest, soil and water conservation forest, wind and sand fixation forest, farmland shelter forest, grass pasture.
Protection forests, road protection forests, coastal shelter forests, etc.
3.2
Shelter forest system
In a certain natural geographical area or a range, based on topographic conditions, land use conditions, major natural disasters and people's production activities
On the basis of the local development of the overall production plan, combined with the edge of the field, roads, water conservancy facilities and residential areas, planting trees with fast-growing and high-yield
The layout of the forests, economic forests, and firewood forests is coordinated to rationally plan and form a complex of shelter forests.
3.3
Soil erosion modulus soilerosionmodulus
The soil erosion modulus is the amount of soil erosion per unit time and unit area, and the unit is t·(km2)-1·a-1 or m3·(km2·a)-1.
3.4
Effective protection area effectiveshelteringarea
Refers to the protection of the specified protective objects (crops, fruit trees or soil) on the leeward side of the forest belt from the wind and wind damage (including physiological damage and mechanical damage)
The area of the injury).
3.5
Reference distance standarddistance
For the measured value of the ecological benefit evaluation index, according to the distribution interval of the reference sample sample value of the indicator, the upper and lower limits of the interval are removed, and the selected
If the reference value is determined, the difference between the measured value and the reference value is the reference distance, which is the distance between the measured value and the given reference value.
