碩士 === 逢甲大學 === 建築碩士學位學程 === 105 === In recent years, there are so many ways proposed to reduce the concentration of Carbon Dioxide (CO2) as people were facing the challenge of global climate change. Carbon reduction and low carbon city are important issues for urban development and the research is of great worth. Kyoto Protocol Regulation reported “Forests play an important role in terms of absorbing Greenhouse Gas. The treaty allows that the car-bon dioxide absorption and emission together with forestation and deforestation since 1990, can be incorporated into net value of reduction”. Tree planting is definitely helpful the reduction of CO2 and the air pollution in the environment, in addition, keeping the ecological balanced, it is also an economical method to reduce carbon emissions. Purpose of tree planting is for the reduction CO2 concentrations in the atmos-phere, however, CO2 sequestration amounts has been an important reference data for greening. At present for many cases carbon sequestration were calculated on the bases of "Greenery Index" of Green Building, but it probably existed a large error when the carbon fixation data is used alone. In this study, we intended to involve three kinds of calculation tools for calculating CO2 sequestration amounts, "Building Greening Indi-cators", "Tree volume Calculation" and "Tree Carbon sequestration calculator by En-vironmental Protection Agency in Taiwan ", respectively, and to compare these data. The results showed that there was a large difference between the using of "Greenery Index" directly and the rest two, "Tree Carbon sequestration calculator" and "Tree volume Calculation". Trees CO2 sequestration amounts were varied depending on some factors such as the environment, tree's age, growth rate and tree’s characteristic. The essential condi-tion for a tree with high benefits (high CO2 sequestration amounts) is that trees must be healthily grown up in a well environment. In this study, instead of “Greenery In-dex”, we consider both "Tree volume Calculation" and "Tree Carbon sequestration calculator" to calculate the CO2 sequestration amounts. As well as to conduct struc-tured interviews with landscape maintenance experts to understand the needs of maintenance of urban park trees so as to figure out the tree species which have high CO2 sequestration amounts and low maintenance demands in urban parks. The results showed that the indigenous species Ficus microcarpa was highest-level CO2 seques-tration amounts, Ternstroemia gymnanthera was lowest; higher demands to maintain-ing management was Libocedrus formosana, Calophyllum inophyllum was lowest maintaining requirement. Exotic species with highest-level to CO2 sequestration amounts was Alstonia scholaris, lowest one was Ceiba speciosa; high demands on maintaining trees specie was Cassia fistula, Magnolia grandiflora was lowest main-taining requirements. In this study, we recommend to collect the CO2 sequestration amounts and the maintaining requirements of trees, in order to classify trees by CO2 sequestration ben-efit and maintaining requirement. Consequently, we can provide more classification options accordingly. Those information could be used on plant selection when the landscape greening design and practice. When doing planting design we recommend-ed to adopt multilayer planting strategies and to choose trees specie with both high-est-level of CO2 sequestration amounts and lowest maintaining requirements.
