摘要：利用LI-6400光合作用测定系统,采用自然条件下离体定位观测和室内分析相结合的方法,对沈阳市5种常用灌木树种固碳释氧生态环境效益进行比较研究。结果表明,5种灌木树种中京山梅花单位叶面积固碳释氧能力最强,日光合总量为220.96mmo.lm-2.d-1,吸收CO2量为9.72g.m-2.d-1,释氧量为7.07g.m-2.d-1;鸡树条荚蒾次之,日光合总量、吸收CO2量、释氧量分别为204.56mmo.lm-2.d-1、9.00g.m-2.d-1和6.55g.m-2.d-1;5种灌木树种单位叶面积平均固碳释氧能力排序为京山梅花>鸡树条荚蒾>风箱果>三裂绣线菊>东北山梅花。
In this paper, the function types of the urban forest in Shenyang city were selected as the experimental sites to study the eco-environmental benefits in carbon fixation and oxygen release of the urban forest with a LI-6400 photosynthesis system. The results are as follows：Amounts per unit leaf area of Philadelphus pekinensis is 220. 96 mmol·m^-2·d^-1, Carbon fixing amounts per unit leaf area of Philadelphus pekinensis is 9. 72 g·m^-2·d^-1, oxygen release amounts per unit leaf area of Philadelphus pekinensis is 7.07 g·m^-2·d^-1. The above indices of Viburnum sargentii are less than those ofPhiladelphus pekinensis, they are 204. 56 mmol·m^-2·d^-1,9. 00 g·m^-2·d^-1 and 6. 55 g·m^-2·d^-1 ,respectively. The indices of Philadelphus schrenkiiis are the lowest in the five shrubs;Capabilities per unit leaf area of the main shrub species in typical functional types of the urban forest are ： Philadelphus pekinensis 〉 Viburnum sargentii 〉 Physocarpus amurensis 〉 Spiraea triloba 〉 Philadelphus schrenkii.
