In order to accurately assess the ecological benefits and value of urban green space, improve the management level of country parks, we took 5 typical forest stands(Cinnamomum cam Phora; Koelreuteria paniculata; Osmanthusfragrans; Sapindus mukorossi Gaertn; Taxodiumascendens) as an objects of study in Pujiang country park of Shanghai, used green quantity equation to calculate the three-dimensional green volume of plants, used the three-dimensional green volume to convert the ecological benefit produced by Stands, and the ecological benefits values of five forest stands were estimated by using several ecological economic methods based on the measurement of each tree. The results showed that the ecological benefit values of the selected five forest stands on the total area of only 0.648 5 hectares was 230 700 yuan/year, equivalent to 355 700 yuan/hm2; with respect of releasing Oxygen quantity and absorbing carbon dioxide quantity, the ecological benefits per hectare decreased in the order:Cinnamomum cam Phora > Koelreuteria paniculata > Osmanthus fragrans > Taxodium ascendens > Sapindus mukorossi Gaertn; with respect to absorption sulphur dioxide quantity, laying dust quantity and transpiration quantity decreased in the order:Cinnamomum cam Phora > Koelreuteria paniculata > Taxodium ascendens > Osmanthus fragrans > Sapindus mukorossi Gaertn; value of ecological benefit per hectare of each stand Order decreased in the oder:Cinnamomum cam Phora > Koelreuteria paniculata > Osmanthus fragrans > Taxodium ascendens > Sapindus mukorossi Gaertn. There is a positive correlation between the ecological benefit of stand, its value and three-dimensional green volume.
