Abstract
Because of difficulties in estimating the carbon fixation rate, we alternatively investigated the C content of the soil in 19 urban parks in the Tokyo metropolitan area. The C content of the soil under three vegetation types was measured: grassland/turf (“turf”); tree-planting area with plant management (with weeding and removal of fallen leaves) (“tree-planting area”); coppice or tree-planting area without plant management (“coppice”); bare land was used as control. Average C contents of turf, tree-planting area and coppice were about 82, 79 and 120 Mg–C ha−1, respectively, and were larger than the C content of trees in an urban park, as estimated in previous studies. The results indicate that the soils of urban parks function as a C sink.
