| 摘 要： | 通过对延安市区常见的绿化树种元宝枫、白桦、火炬树、新疆杨的光响应曲线、光合速率、蒸腾强度、水分利用效率等生理特性进行测定和对比分析表明:新疆杨、火炬树的光合速率、蒸腾速率均明显高于元宝枫和白桦,4个树种的水分利用效率差异不明显.因此,考虑到该地区有限的水资源,宜选择低蒸腾速率的元宝枫、白桦作为延安市的主要造林绿化树种.

| Abstract: | Light curve, photosynthetic rate, transpiration rate, water use efficiency of Acer mono, Betula platyphylla, Rhus typhina and Populus alba were measured and analyzed in this paper. The results show that photosynthetic rate and transpiration rate of Populus alba and Rhus typhina were higher than those of Acer mono and Betula platyphylla ; however, water use efficiency of 4 tree species were similar. Acer mono and Betula platyphylla were selected as major greening tree species in Yan'an city according to their lower transpiration rate,and also the present situation of the limited water resource in this areas. |

| Keywords: | greening tree species photosynthetic rate transpiration rate water use efficiency |
