摘要
近些年城市园林绿化多停留在美学层面.笔者于2013年和2014年4～8月连续两年进行植物叶片瞬时光合速率的测定,得到两年数据的平均值,通过测定树种叶片的光合速率计算净同化量,再换算叶片固定CO2和释放O2的量,根据排序选择合适的园林植物进行搭配,得出基于固碳释氧效益的植物配置模式;以测量差重的方式来测定单位面积叶片的滞尘能力,并求取平均值,根据排序选择合适的园林植物进行搭配,得出基于滞尘能力的植物配置模式.该研究将植物种植的生态效益融入园林绿化之中,旨在使城市绿地在提高居民生活质量的措施中发挥更大的价值.
Abstract
City landscaping stay in aesthetic aspect in recent years.From Apr.to Aug.in 2013 and 2014,the instantaneous photosynthetic rate of plant leaf was determined,the average of two years data was obtained.By measuring tree leaf photosynthetic rate to calculate the net assimilation rate,and converting the leaf CO2 fixation and O2 release amount,according to the order to choose the appropriate greening plant,the plant disposition pattern based on CO2fixation and O2 release benefit was obtained; the dust removal capacity per unit area was determined by measuring weight difference method,the mean was calculated,according to the order to choose the appropriate greening plant,the plant disposition pattern based on dust removal capacity was obtained.The ecological benefits of plants cultivation were integrated into garden greening,in order to make urban green space to play a greater value in improving residents' life quality.
