厦门城市森林碳储量和碳密度时空变化特征
Spatiotemporal dynamics of carbon storage and density of urban forest in Xiamen city
摘要
Abstract
Based on Xiamen forest management planning inventory data in 1972, 1988, 1996 and 2006, the spatiotemporal dynamics of urban forest carbon storage and carbon density of major vegetation types in different urbanization zones were analyzed by the method of variable biomass expansion factors and GIS. The results showed that forest carbon storage had increased by 865 589.71 t from 1972 to 2006 (34 years) in Xiamen, with a rapid increase trend from 1972 to 1996, and then relatively slight decrease from 1996 to 2006. The order of carbon storage along the urban gradient was urban core < suburb < exurb, while carbon density was contrarily urban core > suburb > exurb. That was mainly due to the larger proportion of exurban and suburban areas and the differences in vegetation types, stand ages in these three zones. The underlying reasons were that as urbanization developed rapidly, carbon sink of urban forest was affect by LUCC, afforestation, forest management and so on.关键词
