The Evaluation On Forest Ecosystem Service Value Of Daxing' Anling Forest In Inner Mongolia

In this article, forest ecosystem service of Daxing'anling forest Inner Mongolia as the research object, mainly use the positioning observation data of Forest Ecosystem Research Station Daxing'anling Inner Mongolia, to collect relevant data, supplemented by relevant data to collected, done by conducting field investigations and laboratory tests to supplement the lack of data, comprehensive use of ecology, ecological economics, mathematics and other related knowledge, application of physical and value of combining methods, according to the State Forestry Administration released assessment specification of forest ecosystem services in 2008(LY/T1721-2008), Daxing'anling forest in Inner Mongolia's physical capacity and the magnitude of value for a simple estimate. Make it more intuitive to see the tremendous economic benefits from cold temperate coniferous forest in Inner Mongolia, to Enhance people's awareness of ecological protection, to provide the basis for Cold temperate coniferous forest in Inner Mongolia's sustainable development and Ecological planning.the research result as follows:1. through careful analysis of ecosystem services assessment index system in domestic and foreign, combination of forest ecosystem services features Daxing'anling Inner Mongolia, Established a set of ecosystem services index system of cold temperate coniferous forest in Inner Mongolia, 1 indexes of first grade(forest ecosystem service of Cold temperate coniferous forest Inner Mongolia),7 of second grade(Water conservation, Soil and water conservation, air purification, nutrient accumulation, C fixation and O2release, forest tour, maintaining biodiversity) and 11 of third grade(Water Regulation, Water purification, Soil conservation, Maintaining soil fertility, C fixation, O2release, nutrient accumulation, provide negative ions, detaining dust,maintaining biodiversity, forest tour) were selected as evaluation indices for evaluation on forest ecosystem service value in Cold temperate coniferous forest in Inner Mongolia.2. the total ecosystem services value of Daxing'anling forest in Inner Mongolia is 9.57×10¹⁰yuan·a-1.The value of Soil and water Conservation is 7.00×10¹⁰yuan·a-1( the value of Soil conservation is 3.92×10⁹yuan·a-1,the value of Maintaining soil fertility is 8.66×10¹⁰yuan·a-1), which made up 73.61% of the total value ;The value of basorbting C02 and releasing 02 is 2.39×10¹⁰yuan·a-1 (the value of basorbting C02 is 2.31×10¹⁰yuan·a^-1,the value of releasing 02 is 0.82×10⁹yuan·a^-1), which made up 25.21% of the total value;The value of maintaining biodiversity is 4.04×10⁸yuan·a^-1,which made up 0.33% of the total value;The value of Water conservation 3.50×10⁸yuan·a^-1(the value of Water Regulation is 2.61×10⁸yuan·a^-1 , the value of Water purification is 8.91×10⁹yuan·a^-1), which made up 0.37% of the total value;The value of nutrient accumulation is 3.11×10⁸yuan·a^-1,which made up 0.33% of the total value;the value of forest tour is 0.68×10⁸yuan·a^-1,which made up 0.04% of the total value;The value of air purification is 6.32×10⁶yuan·a^-1(the value of Providing negative ions is 5.92×10⁶yuan·a^-1,the value of detaining dust is 0.40×10⁶yuan·a^-1), which made up 0.02% of the total value.3. The value of the Soil and water conservation is the most obvious, which made up 73.61% of the total value,and the least value is created by air purification, which made up 0.01% of the total value,The eight kinds of service function value of forest ecosystem are listed in descending order as follows: Soil and water conservation > basorbting C02 and releasing 02 > maintaining biodiversity > Water conservation > nutrient accumulation > forest tour > air purification.
