Ecosystem services and their values: a case study in the Qinba mountains of China

Abstract Terrestrial ecosystem services can provide both direct and indirect economic benefits. In this case study, we estimated the annual economic value of some ecosystem services provided by terrestrial ecosystems in the Qinba mountains of Shaanxi Province of China, using both simulation models and a geographic information system that helps to analyze the effect of ecological factors on ecosystem functions. With respect to differences in vegetation types and their coverage, by combining the latest research, and using theory and methods for the value of terrestrial ecosystem services, we not only calculated goods produced by different types of vegetation but also estimated the value of various terrestrial ecosystem services. We also set up a database and an eco‐account of a terrestrial ecosystem. The ecosystem services assessed relate to the following aspects: the vegetation's primary productivity, soil and fertility conservation, water conservation, carbon fixation and oxygen supply. The total economic value of terrestrial ecosystem services in the Qinba mountains was estimated to be 968.33 billion renminbi per year, and represents a part of the actual ecosystem services. In addition, we analyzed the spatial distribution of the vegetation based on the economic values of the terrestrial ecosystem services. Our findings can contribute to the conservation of these terrestrial ecosystems and the effective use of these ecosystem services.
