摘要
长株潭城市群建设中面临着三市大气叠加污染、林业用地却在被侵占、绿地系统压力过重的问题,如何在有限的绿地面积中增加碳汇,是实现长株潭低碳经济的有效手段。在借鉴国内外研究成果的基础上,针对长株潭特殊的气候、绿地结构与分布、绿地类型,引入C4植物,并分析了C4植物在高速公路绿地、岩石园绿地、屋顶花园、草坪等四种典型环境绿地中的应用前景,从而实现C4植物在长株潭绿地建设中减少水耗、高效率光合作用等功效。C4植物的推广应用将对减少长株潭大气中的碳浓度,降低温室效益,创建低碳型长株潭城市群具有重要意义。
During process of Changsha-Zhuzhou-Xiangtan（CZT） urban agglomeration construction, there existed the superposition of atmospheric pollution from the three cities, embezzlement of forest, overweight of green environmental system pressure. How to increase carbon sequestration in the limited green space is the effective means to achieve the low carbon economy in CZT. According to the special climate of CZT, structure and distribution of green space and green space types, CA plants were introducted and the application prospect was analysed in the four typical green spaces which were highway, rock garden, roof garden and lawn, so as to achieve CA plants reducing water consumption and increasing photosynthesis efficiency in CZT greenbelt construction. The popularization and application of CA plants will have great significance for reducing the CZT atmospheric carbon concentration, decreasing greenhouse effect, and creating a low carbon type of CZT urban agglomeration.
