Abstract: (102 Views)
Background and objectives: In addition to wood production, forests have many environmental and social resources that most of them are often lacking in the market.
Materials and methods: In this paper five cases of ecosystem services forest ecosystem was considered from an economic perspective and they have been evaluated to various approaches. For this purpose, the recreational value of the area by using a conditional valuation method and the value of carbon sequestration, the maintenance of soil nutrients, the value of water regulation and the value of non-food products in the region were estimated by using the replacement cost method. Then the total economic value of these functions was estimated.
Results: According to the results total economic value and the annual value per hectare of forest ecosystem were 576413505.1 Toman and 17243407.560 Toman in year respectively. The functions of Carbon sequestration with equivalent value 574114967.1 thousand Toman had the most value and Recreational function had the lowest total value among other functions with equivalent value 126618 thousand Toman per year.
Conclusion: The results of the study, as well as other similar studies can be concluded that natural resources with regard to the future exploitation process, they are more under pressure and rarer, So it is necessary that with the optimal using of these valuable ecosystems, this natural heritage has been protected. With understanding the economic value of the whole ecosystem, programmers and policymakers are able to make more comprehensive decisions and determine the precedence between available options that makes optimal use of it.
