英文摘要	National key eco-function zones for water and soil conservation are exceptionally fragile areas in terms of their eco-environments and are also severely affected by water and soil loss. They have been a focus of attention from all sectors of society. This research assesses important ecosystem service functions and their values using such indexes as NPP, soil conservation quantity and water conservation quantity. The result indicates that the ecosystem services of China's eco-function zones for water and soil conservation are worth 3268.90×10~8 CNY in total, of which organic matter production accounts for 530.96×10~8 CNY, nutrient substance circulation and storage 301.91×10~8 CNY, carbon fixation and oxygen release 1616.16×10~8 CNY, soil conservation 442.70×10~8 CNY and water source conservation 816.20×10~8 CNY. Of the four functional zones, the Guangxi-Guizhou-Yunnan Area registers the highest value of 1551.30×10~8 CNY, and the Three Gorges Reservoir Area the lowest value of 448.15×10~8 CNY. In terms of ecosystem service value per unit of area, the Guangxi-Guizhou-Yunnan Area takes the first place, followed by Three Gorges Reservoir Area and the Dabie Mountain Area, which are roughly equivalent, and finally the Loess Plateau Area is at the bottom.
