【摘要】 采用森林生态系统定位研究网络台站多年连续观测数据和森林资源清查数据及公共数据对中国杉木林生态服务价值物质量和价值量进行详细评估。结果表明:1994—1998年和1999—2003年期间,中国杉木林生态服务总价值分别为15643.82亿元.a-1和17043.86亿元.a-1,单位面积价值分别为12.62万元.hm-2a-1和12.34万元.hm-2a-1,其中在所评估的六大服务项中各服务项的价值所占比例次序为涵养水源>积累营养物质>固碳释氧>生物多样性保护>净化大气环境>固土保肥。更多还原

【Abstract】 The forest ecosystem services evaluation is one of the hot spots on forest ecosystem research.We assessed the quantity value and the economic value of Chinese Fir(Cunninghamia lanceolata)forest ecosystem services on the basis of the long-term observation of several ecosystem research stations which belonged to the chinese forest ecosystem research network(CFERN),the data of forest resource in China and the data of social commonality.The research was carried out in three aspects(provide air anion,absorb pollutants and the dust catching property).The results showed that the total economic value of Chinese Fir forest ecosystem in 1994—1998 and 1999—2003 respectively are 15 643.82×108 yuan·a-1 and 17 043.86×108 yuan·a-1,the unit area quantity value respectively are 12.62×104 yuan·hm-2 a-1 and 12.34×104 yuan·hm-2 a-1.The sequence of the six services which we assessed is water supply > nutrition storage > carbon fixed and oxygen released > biodiversity conservation > atmosphere environmental purification > soil conservation.更多还原
