城阳街道绿化树种地上生物量及不同绿地类型的碳储量

Aboveground Biomass of Greening Tree Species and Carbon Storage for Different Types of Green Space in Chengyang Street

摘要: 本文利用生物量模型，结合外业调查，分析了青岛市城阳街道主要绿化树种生物量，并利用遥感反演的方法计算了绿地生态系统的碳密度空间分布和不同绿地类型的碳储量。结果表明：城阳街道绿化树种的平均地上生物量差距较大，最大的悬铃木(Plane tree)为1205.67 kg，是最低的鸡爪槭(Acer palmatum)的近80倍；同一树种不同器官之间的生物量存在差异，表现为黑松(Jack pine)、水杉(Metasequoia)等11个树种的树枝生物量大于树叶生物量，剩余11个树种则相反；防护绿地、附属绿地、公园绿地和生产绿地的碳储量分别为1.1314 Tg、0.6003 Tg、0.0748 Tg和0.0369 Tg。本研究为全面估算青岛市绿地生物量及碳储量奠定了基础。

Abstract: Based on the biomass model and the field survey, this study analyzed the biomass of the main af-forestation species in Chengyang Street, Qingdao City, and calculated the spatial distribution of carbon density and carbon storage in different types of green space by using remote sensing in-version method. The results showed that the average aboveground biomass difference of the urban tree species in Chengyang Street was relatively large, the value for the largest biomass tree species Plane tree was 1205.67 kg, which was nearly 80 times as large as Acer palmatum which has the lowest biomass. The biomass of different organs of the same tree species was different, presented as the biomass of branches of 11 tree species such as Jack pine and Metasequoia was greater than the biomass of the leaves, while the remaining 11 tree species were opposite. Carbon storages in the green space for environmental protection, attached green space, park green space and productive green space were 1.1314 Tg, 0.6003 Tg, 0.0748 Tg and0.0369 Tg respectively. This study made contributions to the comprehensive estimation of biomass and carbon storage of green space in Qingdao City.
