| 摘 要： | 生态系统固碳服务是生态系统服务评估的重要指标之一，也是区域碳循环研究的重要组成部分，可以为减缓气候变化的区域碳管理提供决策依据.以厦门市森林生态系统为研究对象，选取VPM（Vegetation Photosynthesis Model）和ReRSM（Remote Sensing Model for Ecosystem Respiration）评估其2015年的固碳服务，并阐明其固碳服务的时空变异.结果表明:2015年厦门市森林生态系统固碳量（以C计）为31.36×104 t/a，平均固碳量为644.86 g/（m2·a），其时间动态总体呈单峰曲线分布，但受台风影响该曲线波动较大.厦门市森林生态系统固碳量空间格局总体表现为西北边缘地区较高、其他地区相对较低，与DEM的空间分布较为相似，且绝大部分区域为碳汇区.厦门市分区统计显示，同安区森林生态系统面积和固碳量均最大，分别占厦门市总量的52.58%和57.10%，其与翔安区、集美区的固碳量之和占厦门市总量的88.27%，是厦门市森林生态系统固碳的主体；湖里区固碳量最少，平均固碳量仅为14.25 g/（m2·a），几乎为碳中性.研究显示，厦门市森林生态系统具有较好的固碳能力.

| Abstract: | Carbon sequestration of terrestrial ecosystem is one of the most important indicators in ecosystem service assessment and is crucial to accurate estimation of regional carbon budget, which could support decision-making for the regional carbon management. In the present study, we estimated the forest ecosystem carbon sequestration and analyzed its spatio-temporal variation in Xiamen City in 2015 by using VPM (Vegetation Photosynthesis Model) and ReRSM (Remote Sensing Model for Ecosystem Respiration). The result showed that the carbon sequestration of forest ecosystem in Xiamen City was 31.36×104 t/a (measured on carbon) in 2015, with an average of 644.86 g/(m2·a). In general, the intra-annual dynamic of carbon sequestration exhibited a single peak curve, but fluctuated greatly under the influence of typhoons. The most areas of forest ecosystem in Xiamen City was carbon sink, with higher carbon sequestration at the edge of northwest and relative lower value in other regions, which was similar to the trend of DEM. At district scale, Tong''an District had the largest forest area and highest carbon sequestration, accounting for 52.58% and 57.10% of the total forest area and carbon sequestration in Xiamen, respectively. Tong''an District, coupled with Xiang''an and Jimei Districts made up 88.27% of the carbon sequestration of the whole city. Huli District was almost carbon neutral with an average carbon sequestration of 14.25 g/(m2·a). This research showed that the forest ecosystem in Xiamen City had a good carbon sequestration capacity. |
