中文摘要：

为了对沈阳市绿化树种的合理配置提供科学依据,本文以沈阳典型城市森林类型为试验区,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,在常用灌木树种蒸腾生理特性分析的基础上,首次对沈阳市主要灌木树种的降温生态环境效益进行了系统研究。结果表明,21种常用灌木单位叶面积的降温效应表现为接骨木〉蔷薇〉风箱果〉东北山梅花〉京山梅花〉大花水亚木〉五叶地锦〉黄刺玫〉水腊〉朝鲜黄杨〉鸡树条荚迷〉紫叶小檗〉金银忍冬〉金钟连翘〉珍珠绣线菊〉忍冬〉榆叶梅〉紫丁香〉锦带花〉红瑞木〉茶条槭。

英文摘要：

The eco-environmental benefit of urban forest was quantitatively estimated based on the processes of photosynthesis and transpiration, which can provide scientific basis for the reasonable layout of urban tree species and for the evaluation of the eco-envi- ronmental benefits of urban forest. The function types of the urban forest in Shenyang City were selected as the experimental sites, the heat absorbance of the urban forest of Shenyang City with a LI-6400 photosynthesis system. The order according to the daily heat ab- sorbance capabilities per unit leaf area of the main shub species were Sambucus williamsii〉 Rosa glanca〉 Physocarpus amurensis 〉 Philadelphus schrenkii〉 Philadelphus pekinensis〉 Hydrangea paniculata vat. grandiflora〉 Parthenocissus quinquefolia〉 Rosa xanthi- ha〉 Ligustrum obtusifolium〉 Buxus sinica〉 Viburnum sargentii〉 Berberis thunbergii var. atropurpurea〉 Lonicera maackii〉 Forsythia suspense〉 Spiraea triloba〉 Louceajaponica〉 Prunus triloba〉 Syringa oblate〉 Weigelaflorida〉 Comus alba〉 Acer ginnala.
