| 摘 要： | 以位于亚热带地区的城市公园(深圳市莲花山公园)绿地为例,选取了碳-氧平衡、水土涵养和小气候调节3方面的CO2-O2吸释量、群落蓄水量、保土量、蒸散量、蒸散耗热量等指标,对城市公园植被的不同群落结构类型进行了生态效应的定量评价.结果表明,有乔、灌、草3层结构的林地群落的生态效应平均为单层结构的草坪群落的2～3倍. |

| Abstract: | Taking the public park green space in the subtropical areas(Lianhuashan Park in Shenzhen City) as an example,three aspects have been put into consideration including the balance of CO_(2) and O_(2),maintenance of soil and water,and the regulation of climate.Based on the indices of CO_(2) absorption-O_(2) release,water holding,soil holding,transpiration and dissipative heat of transpiration,the evaluation of the ecological benefit has been performed for different community structure types.The result shows that the ecological benefits of the forest community with three layer structure of trees,shrubs and grasses are two or three times as much as the lawn community with one layer structure in average. |
