| 摘 要： | 以兰州市为例，分析了大气环境和环境噪声的现状,依现有的城市绿地面积，主要从4个方面估算城市绿地系统的生态效益:(1)绿地在城市碳氧平衡中的作用．(2)从绿地吸收NOx和脱硫两方面估算经济效益．(3)绿地的减噪作用．(4)绿地的杀菌作用．结果表明：乔灌草相结合的复合绿地对细菌的滤除率可达70％以上，草坪对细菌的滤除率也达20％以上．根据兰州市特殊的盆地地形特征，提出了要实现城市的可持续发展，今后的绿化工作重点应放在南北两山．

| Abstract: | The air and yawp conditions in Lanzhou were studied.Based on the existing areas of the green space,the function of the green ecosystem was estimated mainly from four aspects:(1)The function of the green space in carbon and oxygen balance,(2)the economic benefit from two aspects of the green space that absorbing the NO_X and desulfuration was estimated,(3)the function of reducing the yawp,and(4)the function of sterilize.The results suggested complex green space that conjunct with arbor,pour and grass may strain of the bacterial over the 70 %,lawn may strain of the bacterial over 20 %.Based on the special basin terrain character in Lanzhou,in order to come true the sustainable development of the urban,the greening should set the south-north hill green in the future. |
