中文摘要：

It is widely accepted that there is an economic progress beyond the Gross Domestic Product(GDP), while global GDP has increased more than three-fold since 1950, whereas ecosystems have been largely occupied and depleted. Since the 1990 s, emphasis has focused on function and valuation of ecosystem services, which is rarely treated as a market issue. This paper reviews recent developments on measures to evaluate and assess ecosystem services, while elucidating the function of ecosystem services. On the one hand, functions of ecosystem services are subdivided into several items such as gas regulation, water regulation, soil and nutrient recycling. Also, there exist intellectually guided functions of ecosystem services, such as culture and recreation. On the other hand, ecosystems can be viewed as a supplier in the trade between human beings and natural resources such that all resources can be labeled and quantified.

It is widely accepted that there is an economic progress beyond the Gross Domestic Product （GDP）, while global GDP has increased more than three-fold since 1950, whereas ecosystems have been largely occupied and depleted. Since the 1990s, emphasis has focused on function and valuation of ecosystem services, which is rarely treated as a market issue. This paper reviews recent developments on measures to evaluate and assess ecosystem services, while elucidating the function of ecosystem services. On the one hand, functions of ecosystem services are subdivided into several items such as gas reg- ulation, water regulation, soil and nutrient recycling. Also, there exist intellectually guided functions of ecosystem services, such as culture and recreation. On the other hand, ecosystems can be viewed as a supplier in the trade between human beings and natural resources such that all resources can be labeled and quantified.
