Evaluation of Service Function Value of Forest Ecosystem for Natural Forest Protection Project in Xiuwen County

Abstract

According to LY/T 1721-2008 Forest Ecosystem Service Function Evaluation Specification, this paper constructs a forest ecosystem service function evaluation index system for the natural forest protection project based on the characteristics in the process of implementation of the natural forest protection project in Xiuwen County, and assesses the value of forest ecosystem service function of the natural forest protection project in Xiuwen County from 1998 to 2015 by using materials of Xiuwen County natural forest protection project, forest resource inventory data, and ecological monitoring materials. The results show that the total value of the forest ecosystem service function value of the Xiuwen County Natural Forest Protection Project in Guizhou Province reached 29.281 billion by 2015, the annual average is 1.62712 billion yuan, and the total value is increasing year by year. Among the different forest ecosystem service functions, two functions carbon sequestration and oxygen production and water conservation a have the largest value that shows that the Xiuwen County Natural Forest Protection Project plays an important role in carbon sequestration and oxygen production and water conservation. In response to the existing problems, suggestions for improving the service functions of forest ecosystems are put forward.
