The impacts of land utilization change on the ecosystem service values in Daqing during 1995 to 2015 were analyzed based on unit area ecosystem service value of Chinese territorial ecosystem from Mr. Xie Gaodi and ecosystem service value calculation formula from Costanza. Results showed that the ecosystem service value of Daqing decreased from US $4343.1559m in 1995 to US $3824.327m in 2015, wi...

Forest ecosystem services are fundamental for human life. To protect and increase forest ecosystem services, the driving factors underlying changes in forest ecosystem service values must be determined to properly implement forest resource management planning. This study examines the driving factors that affect changes in forest ecosystem service values by focusing on regional forest characteri...

Critics of the market-based, ecosystem services approach to biodiversity conservation worry that volatile market conditions and technological substitutes will diminish the value of ecosystem services and obviate the "economic benefits" arguments for conservation. To explore the effects of market forces and substitutes on service values, we assessed how the value of the pest-control services pro...

With the measurement of net primary productivity and vegetation coverage fraction based on remote sensing data,the terrestrial ecosystem service value of China in 2000 was quantitatively estimated as 9.17 x 10(12) yuan (RMB). The spatial distribution of the ecological service value showed a decreasing trend from southeast China to northwest China, which was consistent with the regional distribu...

ABSTRACT Background: Natural ecosystems provide necessary services for human beings, including ecosystem service values (ESVs) and socioeconomic (SSVs). The value orientations of ESVs SSVs are mainly related to people’s interaction with nature. This study reclassified greenspace from a perspective exposed non-exposed based on the level by people greenspace. We applied an expert questionnaire su...
