Research On Ecosystem Service Function Of Guposhan National Forest Park In Guangxi Province

Guposhan National Forest Park has a pleasant climate, just like spring most of year, abundant in species, clean air, beautiful environment, rich negative ion in the air, so it is a good place for tourism, vacation, recuperating. The various advantages, mostly due to the presence of Guposhan forest ecosystem.In order to provide a scientific basis for protection and sustainable utilization of the Guposhan forest ecosystem, management of forest park, and making ecological compensation policy. Based on field investigation and indoor analysis, community survey and determination of related indicators were carried out. on the basis of the data,12evaluation indexes of7function types of Guposhan National Forest Park forest ecosystem were analyzed and evalued.In2013, the total value of7ecosystem service functions of main forest types in Guposhan National Forest Park was9.008×108Yuan/a, and the value of ecosystem service per unit area is14.446×104Yuan/(hm2a). Values and percentages of7functions of the main forest types in Guposhan National Forest Park were4.241×108Yuan of water conservation (45.002%),0.474×108Yuan/a of soil conservation (5.029%),0.710×108Yuan/a of carbon fixation and oxygen release (7.535%),0.062×108Yuan/a of nutrient accumulation (0.663%),0.270×108of atmospheric environment purification (2.867%),2.830×108Yuan/a of biological diversity protection (27.665%),0.420×108Yuan/a of forest recreation (11.239%), respectively. The forest ecosystem services functions, according to the order of its value from high to low, are water conservation, biodiversity conservation, carbon fixation and oxygen release, soil conservation, recreation, air purification, nutrient accumulation. Different forest types in Guposhan National Forest Park, according to the order of total values of the ecosystem service functions from high to low, are broadleaf trees, shrubs, China fir, pine, bamboo, economic trees, ranked in the top three of broadleaf trees, shrubs, China fir, economic tree is in the last row. According to value of ecosystem service function per unit area from high to low, the order is broadleaf tree, bamboo, shrubs, economic tree, pine trees, China fir, and broadleaf tree, bamboo, shrubs, are in the top three, China fir is in the last row.According to the characteristics of forest ecosystem service functions of Guposhan National Forest Park, some suggestions on forest management were proposed, for example, improving forest structure of forest, riching forest eco-tourism characteristics, and strengthening monitoring forest ecological system.
