Environmental monitoring of national-level comparisons of CO(2) emissions is needed to quantify sources and sinks of carbon (C) in national ecosystems. In this study, a national forest inventory database was used to estimate the past and current pools and fluxes of C in deciduous and coniferous forest and woodland ecosystems (20.7 x 10(6) ha) of Turkey. Growing C stock was 12.63 t C ha(-1) in 1960 and 16.55 t C ha(-1) in 1995. Total C store in the whole live woody biomass was estimated at 22.77 t C ha(-1) in 1996. The total flux of C from the atmosphere into the forest and woodland ecosystems driven by primary productivity was about 1.46 t C ha(-1)(or 30.2 Mt C) in 1996. The estimated net release of C from the forest and woodland ecosystems of Turkey to the atmosphere was about 1.34 t C ha(-1)(or 21.5 Mt C) in 1996. When C released was taken into account, net ecosystem sequestration (NES) resulted in 0.12 t C ha(-1) per year. Such analytical tools as national forest C budgets are needed to improve our preventive and mitigative strategies for dealing with global climate change.
为了量化国家生态系统中碳（C）的源和汇，需要对二氧化碳排放进行国家级比较的环境监测。在本研究中，利用国家森林资源清查数据库估算了土耳其落叶林、针叶林和林地生态系统（2070万公顷）过去和当前的碳储量及通量。1960年生长碳储量为12.63吨碳/公顷，1995年为16.55吨碳/公顷。1996年整个活木生物量中的总碳储量估计为22.77吨碳/公顷。1996年，由初级生产力驱动的从大气进入森林和林地生态系统的碳总通量约为1.46吨碳/公顷（或3020万吨碳）。1996年，估计土耳其森林和林地生态系统向大气净释放的碳约为1.34吨碳/公顷（或2150万吨碳）。考虑到释放的碳，净生态系统固存（NES）每年为0.12吨碳/公顷。需要诸如国家森林碳预算这样的分析工具来改进我们应对全球气候变化的预防和缓解策略。
