Based on the published studies and the data from multiple-year consecutive observation of the Long Term Ecological Research Station affiliated to the Chinese Forest Ecosystem Research Network (CFERN), the ecosystem services of carbon fixation and oxygen release, water conservation, soil conservation and nutrient accumulation of the Changbai Mountain Natural Reserve (CMNR), PR China, from 1985 to 1997 were evaluated using the Specifications for Assessment of Forest Ecosystem Services in China (LY/T17212008) promulgated by State Forestry Administration of China. The results show that the loss of ecosystem service value in CMNR was 59.76 million dollar under the policy intervention. These ecosystem services show trade-off/synergistic relationship. Carbon fixation and oxygen release, water conservation and soil conservation decreased greatly, while nutrient accumulation slightly increased from 1985 to 1997. This research could provide a scientific basis for policy-making in sustainable development of natural reserves.

This paper draws attention to the changing status of studies on the restoration ecological economic value with regard to vegetation restoration. It presents an attempt to calculate the dynamic economic value in the process of vegetation restoration in Xiaoliang, tropical China. The results showed that restoration ecological economic value increased from 509 RMB•hm-2 to 119,070 RMB•hm-2 during the 45 years. With the vegetation restoration went on, the increasing velocity slowed down. In the first 15 years, the velocity was more than 100% and slowed down gradually then after 20 years later. If compared by value construction, the direct economic value increased from 101 RMB•hm-2 to 32,782 RMB•hm-2 during the 45 years, and the indirect economy value increased from 408 RMB•hm-2 to 86288 RMB•hm-2. From the perspective of the value amount of each service function in the restoration process of the degraded ecosystem, the value amount was ordered as O2 relief > Carbon sequestration > Soil conservation > Climate regulation > Water conservation. And also, the tendency of each value was different, soil conservation service function and the climate regulation were the most remarkable here, after restored for 20 years, the soil conservation remained stable, the soil conservation economy value presented the same tendency, while the value of climate regulation fluctuated after 15 years’ restoration. The results suggest that the restoration ecological economic value was a time-dependent, dynamic accumulation consistent with the ecological effect of the restored forest. In addition, the restoration ecological economic value at different ages in a restored forest ecosystem was consistent with the values found for some regional natural forest ecosystems. These results may be of importance for ecological restoration and forest management in tropical and subtropical regions.

Core Function

In this study, the ecosystem service function value of Lingang wetland park was calculated,such as hydrological regulation,water conservation and purification, biological habitat, erosion control, carbon sequestration and oxygen release port,with the market value method, carbon tax and forestation cost method, shadow engineering method, replacement cost method ,ecological value method and other methods. The results showed that the total ecosystem service function value of this wetland park is ¥1.03×108•a-1. The species habitat, carbon sequestration and oxygen release and hydrological adjusting function value is larger, which is 40.3%, 38.3% and 13.0% of the total value, so they are the main core function value of the Park. Therefore, the scientific and rational planning should be carried out in the development of the wetland park, avoiding influencing the ecosystem service function of this park.
