Study On Forest Ecosystem Service Value Assessment

Forest ecosystem is one of the most important components of natural ecosystem,and it plays an important role in the coordination of natural environment and economic development.Study on the assessment of forest ecosystem service value can make people and government more intuitive feel the forest ecosystem' s ecological benefits and economic benefits,and further strengthen the awareness of forest ecosystem protection,and thus scientifically control the relationship between forest ecological environment and economic development.This paper takes Tianjin Baxianshan National Nature Reserve as the research area.Based on the data of UAV orthophoto image,satellite remote sensing image,meteorology,field investigation.This paper selected organic matter production,accumulated nutrients,carbon fixation and oxygen release,water conservation,soil conservation,air purification,biodiversity conservation,forest recreation as forest ecosystem services assessment indicators.This paper calculated the material quality and value according to Specification for assessment of forest ecosystem services in China.The results of this paper show that the overall forest ecological service has a good function.Each of the services has high value.Sort the value in descending order:carbon fixation and oxygen release,water conservation,biodiversity conservation,soil conservation,forest recreation,purification of atmospheric environment,organic matter production,nutrient elements accumulation.The technical method used in this paper can provide reference for the forest ecosystem services value assessment in other regions.The calculation results can present suggestion to the management of Tianjin Baxianshan National Nature Reserve,and provide the basis for ecological protection and economic coordination development in Beijing-Tianjin-Hebei region.Finally promote the construction of ecological civilization in the whole region.
