摘要:

海岸带蓝碳是介于海洋蓝碳和陆地绿碳之间的一种碳库,拥有巨大的碳汇潜能,对其固碳能力的研究具有重要的现实意义。本文选取1997年、2007年和2017年3个时间点的胶州湾遥感数据,在ArcGIS中解译获取胶州湾海岸带湿地数据,基于InVEST模型,对胶州湾海岸带蓝碳分布的时空格局演变及其服务价值进行评估。研究结果显示:①从时间上来看:1997—2007年和2007—2017年蓝碳总量分别是3.49亿t和2.32亿t,呈减少趋势。②从空间上来看:1997—2007年间蓝碳最大值主要分布在潮下带区域和河套、上马、棘洪滩、九龙街道的芦苇、碱蓬、大米草和养殖池区域,2007—2017年间主要分布在九龙、流亭、棘洪滩、上马街道的养殖池和芦苇区域。③1997—2017年20年间胶州湾蓝碳总价值为8522.13亿元,海岸带拥有巨大的碳汇潜能,保护海岸带生态系统刻不容缓。本文结果可为海岸带生态系统服务价值评估提供有益参考。

Abstract:

Coastal blue carbon is a carbon pool similar to marine blue carbon and terrestrial green carbon, which has huge carbon sink potential and it is of important practical significance to study its carbon sequestration capacity. In this study, remote sensing data of the Jiaozhou Bay in 1997, 2007, and 2017 ,were used for interpretation and acquisition of coastal wetland data in the Jiaozhou Bay area by ArcGIS,.Based on the Integrated Valuation of Environmental Services and Tradeoffs(InVEST) model, this study evaluated the change of spatial and temporal patterns of blue carbon distribution and its service value in the Jiaozhou Bay coastal zone. The results show that: (1) In terms of time: the total blue carbon in 1997-2007 and 2007-2017 was 3.49 × 10 8 and 2.32 × 10 8 tons respectively, showing a decreasing trend. (2) Spatially, from 1997 to 2007, the maximum blue carbon was mainly distributed in the sub-tidal zone and the areas of reed, suaeda salsa, spartina and aquaculture ponds in Hetao, Shangma, Jiuhongtan, Jiulong Street, and in the areas of aquaculture ponds and reeds in Jiulong, Liuting, Jinghongtan and Shangma Street from 2007 to 2017. (3) The total value of blue carbon in the Jiaozhou Bay in recent 20 years is 8522.13×10 8 CNY, it is urgent to protect the coastal blue carbon ecosystem because of its huge carbon sink potential.
