The Selection of high-carbon-sequestration tree species based on their carbon sequestration capacity is a fmdamental task formaxuizig the carbon sik potental. of utban andscaving trees, wus study utilized fixed-plot monitoumng data colected fronurban panks in Shanghai to develop power function models of annual carbon sequestration per tree as a function of diameter atbreast height (DBH) for six representative landscaping tree species (groups), including Caphora officinarum, Metasequoiaglptostroboides, Ligustrum lucidumn, Koelreuteria bipinnata, Magnolia grandifora, and Taxodium species. The capacities forcarbon sequestration of these species were systematically quantifed. The results are as follows: (1) The power fimction modelsof annual carbon sequestration per tree as a fiction of DBH for the six species (groups) showed good fit, with R' values ranging fiom 0.682 to 0.989: (2) Annual carbon sequestration per tree increased signifcantly with DBH, and the ranking of carbonsequestration capacity among species (groups) varied with increasing DBH: (3) Within the standard DBH range, K, bipiunata(14.0 kg/tree/a) and C. oficinarumn (12.9 kg/tree/a) exhibited the highest average annual carbon sequestration, followed byTaxodium species (7.61 kgltreela). while L. lucidum (4.71 kg/treela). M. glyptostroboides (3.79 ketreela). and M. gramdifora'2.78 ke/treela) showed relatively lower seouestration capacities, This shudy aims to provide a scientihc basis for selecting treespecies to enhance the carbon sink capacity of uban landscaping in Shanghai.
