摘要
本文通过实测广州市内几种常见绿化树木的光合强度和呼吸强度以及叶面积指数，计算城市绿地吸收二氧化碳和释放氧气的能力。得出各种树木的叶片光合强度。由于各树木的叶面积指数不同，绿地的吸碳放氧能力也不同。据此，从人类呼吸的基本需要考虑，探讨了城市绿地定额指标问题。
By measuring the photosynthetic intensity, respiratory intensity and leaf area index of several common kinds of afforestatal tree on the-spot in Guangzhou, the author calculates the ability of absorbing carbon dioxide and evolving oxygen of urban green belt and obtain the data of photosynthetic intensity of each kind of leaf blade. Becauce leaf area index of each kind of thee is different, the ability of green bell to absorb carbon dioxide and evolve oxygen is different. Considering the essential requirement of human respiration, the question of urban green belts norm is inquired in this paper.
