Value Of Forest Ecosystem Services Of JiuwanMountain Natural Reserve

Natural ecosystem is the foundation of human survival and development. Natural ecological system not only provides survival space and resources for us, it also has its own ecosystem service function at the same time. The provisioning services, regulating services, cultural services and support services human obtained from the ecosystem all belong to the category of ecosystem service function. In the ecosystem service function, the is the important part of it.Started from the relevant research on domestic and foreign forest ecosystem service function, based on the "forest ecosystem service function evaluation standard" (LY/T1721-2008) and took sample survey and experimental data of Jiuwanshan core nature reserve as the basis as well as reading the "Forest Resources Planning and Design Investigation Report of Jiuwanshan National Nature Reserve" as reference, this paper constructed the evaluation index system to evaluate the forest ecosystem service value of Jiuwanshan National Natural Reserve. The results showed that:The total value of the forest ecosystem service function of Jiuwanshan National Nature Reserve is 234096.78 millionRMB/a and the value of the forest ecosystem service function of average unit area is 10.45 million RMB/a-hm2. In each ecosystem service function, the relationship is water conservation (132198.24 million RMB/a)> protection of biological diversity (42241.14 million RMB/a)> carbon fixation and oxygen release (37433.96 million RMB/a)> forest products (12106.46 million RMB/a)> soil conservation (9624.30 million RMB/a)> purification of atmosphere environment (266.92 million RMB/a)> accumulation of nutrients (225.76 million RMB/a). On the basis of evaluation of the forest ecosystem service value of Jiuwanshan National Natural Reserve and measured from the point of view of the forest ecological compensation of the reserve, the forest ecological compensation standard of Jiuwanshan National Nature Reserve is about 41525.99 million RMB per year. At last, on the basis of the above analysis, this paper proposed countermeasures and suggestions to enhance the forest ecosystem service function value of Jiuwanshan National Nature Reserve. For example, to further improve the reserve management system, to add reserves management station and ecological station, to detect the ecological change state of forest resources in the reserve, to increase the propaganda work of the reserve, to establish ecological compensation mechanism and to establish multi-directional cooperation with universities, especially with agricultural and forestry universities etc.
