The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt & Three Bays, One Core & Six Towns, Two Axes & Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.展开更多

Taking Living Water Park in Chengdu for example, planning of urban public disaster-prevention green spaces was analyzed to further explore planning of urban disaster-prevention green space system and refugee spaces, and provide instructions for the planning and construction of urban disaster-prevention green spaces in China.展开更多

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...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-0.66~11.22kg C/m^2和1.65~8.35 kg C/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 kg C/m^2和0.01~0.71kg C/(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 kg C/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。展开更多
