低碳型城市是我国城市发展的目标,园林植物通过吸收二氧化碳释放氧气在增加碳吸收方面具有重要作用,为此园林建设中要努力发挥园林植物的碳汇功能。本文从两个方面论证了如何利用园林绿地增加城市碳汇。一、发展屋顶花园增加绿化面积,提高城市绿化率;二、合理选择树种,提高园林植物的固碳释氧率。
Low-carbon cities are the goal of urban development in our country. Garden plants play an important role in increasing carbon absorption by absorbing carbon dioxide. Therefore, garden plants should strive to give full play to the carbon sequestration function of garden plants. This article demonstrates from two aspects how to use urban green space to increase urban carbon sinks. First, the development of roof garden to increase the green area, increase the rate of urban greening; Second, a reasonable choice of species, improve plant carbon fixation oxygen rate.
