植被生态服务功能经济价值测评研究——以陕南秦巴山区为例

摘要

According to differences in vegetation types and their coverage, combining the latestresearch, using theory and method on the value of vegetation ecosystem services, this paper not onlycalculated goods produced by different types of vegetation but also estimated the value of variousvegetation ecosystem services and set up database, GIS and eco-account of vegetation ecosystem. Theresult was as follows: the value of vegetation's primary productivity, soil and fertility conservation,water conservation, CO2 fixation and O2 release was 199.6 billion yuan/a, 22.64 billion yuan/a, 22.66billion yuan/a, 352.24 billion yuan/a and 374.19 billion yuan/a, respectively. The total value ofecosystem services was 968.33 billion yuan/a. The temperate deciduous broad-leaved forest had thehighest contribution rate, accounting for 16.42%. The result of value can reflect regional reality moreexactly.
