摘要:

城市绿地在光合作用中能够固定大气中的二氧化碳,但同时会产生碳排放,这给量化城市绿地的固碳能力增加了难度。以广州市为例,通过建立城市绿地碳足迹评估模型,评估和揭示城市绿地碳源、碳汇特征及其影响机制。研究结果表明,包括道路绿地和公园绿地在内的7个研究区的植被和土壤碳储量分别为-0.66~11.22kgC/m 2和1.65~8.35 kgC/m 2;建造施工阶段和管理养护阶段的碳排放量分别为0.63~1.78 kgC/m 2和0.01~0.71 kgC/(m 2·a)。绿地碳足迹等于绿地全生命周期中碳排放量减去碳储量,7个研究区的碳足迹为-2.63~1.99 kgC/m 2。公园密植林区绿地均呈现碳汇特征,道路绿地大多呈现碳源特征,城市绿地的碳源汇特征随着绿地年龄的增加会有所改变。据此分析绿地规划设计对碳收支的影响程度,并提出科学的低碳化绿地管理和调控措施。

Abstract:

Since the urban green space can accumulate organic carbon by photo synthetic,but green space itself will also produce carbon emissions.This increases the difficulty of quantifying urban green space as carbon sinks.With Guangzhou City as an example in this research,the characteristics of urban green spaces and their impact system were revealed,the assessment method for the carbon footprint in the urban green spaces was established,and the contribution of planning and management measures to aggregate carbon reception and emission in urban green spaces was determined.The research results indicated that the carbon reserve in the vegetation and soil in the 7 research zones including green spaces on the roads and in the parks were -0.66~11.22kg C/m 2 and 1.65~8.35kgC/m 2 respectively,and the carbon emission in the phase of construction,management and maintenance were 0.63~1.78kgC/m 2 and 0.01~0.71kgC/(m 2·a)respectively.The total footprint in 7 research zones was -0.263~1.99 kgC/m 2.The characteristics of carbon sinks in the parks and the characteristics of carbon emissions on the roads were mostly different.The carbon sinks or emissions of urban green spaces will change with the increase of age.Based on the results,the influence of planning design for green spaces on carbon reception and emission is analyzed and the scientific and low-carbon managerial and regulatory measures for green spaces are put forward.

Key words: urban green space, carbon storage, carbon emissions, carbon footprint, low carbon design, management and planning
