Embodiment

[0064] This embodiment provides a method for calculating and evaluating the value of forest ecosystem services, including the following steps:

[0065] Classify forests according to the characteristics of forest land types;

[0066] Calculate the value of forest by-products, water conservation, carbon fixation and oxygen release, nutrient cycle value, air purification value, soil conservation value and biodiversity value for each forest land type;

[0067] The sum of forest by-product value, water conservation value, carbon fixation and oxygen release value, nutrient cycle value, air purification value, soil conservation value and biodiversity value of all forest land types is the forest ecosystem service value.

[0068] The calculation formulas for the value of forestry by-products, water conservation, carbon fixation and oxygen release, nutrient circulation, air purification, soil conservation and biodiversity are as follows:

[0069] u 生 =G 生 ×A 1 ;

[0070] Among them...

Abstract

The invention relates to a forest ecosystem service value calculation and evaluation method and device. The method comprises the steps that classifiying forests according to forest land type characteristics; calculating a forest byproduct value, a conservation water source value, a carbon fixation and oxygen release value, a nutrient substance circulation value, an air purification value, a conservation soil value and a biodiversity value of each forest land type; and finally calculating to obtain the forest ecosystem service value. The present and past forest ecosystem service values can be evaluated through the forest ecosystem service value, and the future development trend of the forest ecosystem service value can be predicted.

Description

technical field [0001] The application belongs to the technical field of forest value assessment, and in particular relates to a calculation and assessment method and device for forest ecosystem service value. Background technique [0002] The forest ecosystem is the natural ecosystem with the most perfect function and the most complex structure in the terrestrial ecosystem. It has a decisive impact on the terrestrial ecological environment and is of great significance to the sustainable urban ecology. In recent years, in order to improve the trend of ecological environment deterioration caused by rapid urban development, the service value of forest ecosystem has been paid more and more attention, and forest development has become a research hotspot. [0003] Wang Bing, Xiao Qiang, Zeng Wei et al. conducted research on forest ecosystem service value evaluation from the perspective of ecological function, and quantified the change trend of forest ecological function through e...
