通过对闽北山地天然次生林择伐试验样地15 a的跟踪调查,采用实物量和价值量相结合的评价方法,从涵养水源、保育土壤、固碳释氧3方面分析不同强度择伐后森林生态服务功能恢复动态。结果表明：相对于未采伐林地,伐后10 a,弱度和中度择伐其生态服务功能得到恢复并略有改善,强度和极强度生态服务功能尚未恢复;伐后15 a,4种强度的生态服务价值均得以恢复。从采伐对生态服务价值的影响看,影响程度最大、最难恢复的是保育土壤,其次是涵养水源。因此,对天然次生林的可持续经营,在确定择伐强度和择伐周期时,应考虑林分生态功能的修复过程。

Logging will inevitably cause damage to the environment, thus affect the forest ecosystem service. Through the 15 years of tracking investigation on natural secondary forest selective cutting plots in northern Fujian, recovery dynamic of physical quantity and the corresponding value of forest e- cosystem services was evaluated from water conservation, soil conservation, carbon fixation and oxy- gen released. The results showed that compared to non cutting plot, forest ecosystem services with low and medium intensity were recovered and improved slightly after 10 years, while that of high and ex- tra-high intensity were unrecovered yet. After 15 years., forest ecosystem services with all kinds of se- lective intensity were restored. From the impact of cutting on the ecosystem service value, the largest degree influence and the most difficult to restore is the soil conservation, the second is water conserva- tion. Therefore for the sustainable management of natural secondary forest, forest ecological restora- tion process should be considered when determined selective intensity and selective cycle.
