This study analyzes the impacts of spatiotemporal changes on C dynamics based on the various C pools and forest structure in western Turkey. The forest C dynamics were projected by forest inventory data between 1972 and 2016, and the spatial distribution of C storage was mapped by GIS. Total C storage increased from 1135.22 Gg in 1972 to 1816.60 Gg in 2016 with a net accumulation of 681.38 Gg. While the largest contribution to C pool was from soil organic carbon with 58.6% and 49.3% of the total C storage in 1972 and 1994, it was from living biomass with 54.0% and 57.7% in 2004 and 2016, respectively. The mean annual C sequestration was 1.57 Mg ha−1 year−1, including 1.49 Mg ha−1 year−1 in biomass and 0.08 Mg ha−1 year−1 in soil over four decades. The mixed cover type was the most significant contributor to biomass, soil, and total C storages. However, the hardwood cover type was the most significant contributor to C densities due to the higher growing stock. The mature development stages (35.6 Gg year−1), the fully covered areas (13.2 Gg year−1), and the older forests have played an essential role in C sequestration. The spatial distribution of C dynamics was heterogenic due to forest cover type, forest structure, and species composition. Monitoring spatiotemporal changes in forest ecosystems in terms of forest cover type, development stage, coverages, and age class distribution can provide opportunities in developing effective forest management policies based on the ecological sustainability of C pools and mitigating climate change effects.

土耳其西部森林碳库中碳储量的时空变化:1972-2016年。

本研究基于土耳其西部的各种碳库和森林结构,分析了时空变化对碳动态的影响。利用1972年至2016年的森林清查数据预测了森林的碳动态,并使用GIS绘制了碳库的空间分布图。总C储量从1972年的1135.22 Gg增加到2016年的1816.60 Gg,净积累量为681.38 Gg。1972年和1994年,对碳库的最大贡献来自土壤有机碳,分别占总碳存储的58.6%和49.3%,而来自活生物质的碳分别在2004年和2016年分别占54.0%和57.7%。年平均碳固存为1.57 Mg ha - 1 年-1,其中生物量为1.49 Mg ha - 1 年-1和0.08 Mg ha -1在过去的40 年中,土壤中的- 1年。混合覆盖类型是生物量,土壤和总碳储量的最大贡献者。但是,由于存量增加,硬木覆盖类型是C密度的最主要贡献者。成熟的发展阶段(35.6 Gg年-1),完全覆盖的区域(13.2 Gg年-1)),而较老的森林在固碳中发挥了重要作用。由于森林覆盖类型,森林结构和物种组成,碳动力学的空间分布是异质的。监测森林生态系统的时空变化,包括森林覆盖类型,发展阶段,覆盖范围和年龄等级分布,可为基于碳库的生态可持续性制定有效的森林管理政策和减轻气候变化影响提供机会。
