中文摘要：

采用影子工程法、机会成本法、产量—价格法、产值替代法和净收益替代法等方法,对梅州市1996年、2001年和2007年的森林生态系统服务中的木材价值、涵养水源价值、土壤保持价值、固碳释氧价值、森林净化空气价值、森林资源游憩价值、就业价值和生物多样性价值的动态变化进行估算。结果表明：梅州市1996年、2001年、2007年的森林生态系统服务价值分别为202.81×108元、216.09×108元、246.66×108元,间接经济价值和直接经济价值的比重约为4.8∶1、4.0∶1、3.0∶1。近十几年来该市的生态价值总值逐渐增加,间接经济价值占总价值的比例逐渐变小,主要由生态价值变化不大、直接经济价值增长迅速导致。对推算结果进行对比分析,为梅州市森林生态效益合理补偿和森林资源的科学经营、永续利用提供可靠依据。

英文摘要：

By adopting shadow project method,opportunity cost method,production-price method,output substitution method and net income substitution,etc.,the dunamic changes of wood value,water conservation value,soil conservation value,fixing carbon and releasing oxyen value,forest＇s purifying air value,recreational value of forest resources,employment value and biodiversity value were estimated for Meizhou City during the service process of forest eco-system in 1996,2001and 2007.The results show that the total values of the service function of the eco-system in the three year＇s were 20.28 billion Yuan,21.61 billion Yuan and 24.67 billion Yuan respectively,the three year＇s ratio between indirect economic value and direct ecnomic value were 1∶4.8,1∶4.0,1∶3.0.For the recent 15 years,the ecology value of the city has been gradually increasing,the ration between indiredt economi value and direct economic value has gradually decreasing because direct economic value had a fast development,but indirect economic value had a litter change.The comparison of estimation results among the three years provide a reference basis for Meizhou City in reasonal compensation of forest ecological benefit and scientific management,sustainable utilization.
