中文摘要	对乌兰布和沙漠耐旱植物沙拐枣属、柽柳属、锦鸡儿属的14种植物进行光合日变化特征研究。结果表明:(1) 14种沙生灌木净光合速率日变化呈双峰型,峰值均出现在10:00与16:00,有明显的光合午休"现象,且主要是由气孔因素引起的。净光合速率日均值排序为:柠条锦鸡儿>中间锦鸡儿>乔木状沙拐枣>多花柽柳>细穗柽柳> 白皮沙拐枣 > 东疆沙拐枣 > 甘蒙柽柳 > 荒漠锦鸡儿 > 多枝柽柳 > 头状沙拐枣 > 长穗柽柳 > 狭叶锦鸡儿 > 红皮沙拐枣;(2)沙拐枣属、柽柳属蒸腾速率日变化呈单峰型,峰值分别出现在10:00,14:00,锦鸡儿属植物蒸腾速率日变化呈双峰型,峰值出现在10:00,16:00。蒸腾速率日均值排序为:多花柽柳>细穗柽柳>甘蒙柽柳>柠条锦鸡儿>荒漠锦鸡儿 > 中间锦鸡儿 > 多枝柽柳 > 白皮沙拐枣 > 长穗柽柳 > 乔木状沙拐枣 > 狭叶锦鸡儿>头状沙拐枣>东疆沙拐枣>红皮沙拐枣;(3) 14种沙生灌木水分利用效率日变化均为双峰型,上午的水分利用效率高于下午,最高值出现在10:00,水分利用效率日均值排序为:乔木状沙拐枣>红皮沙拐枣>长穗柽柳>柠条锦鸡儿> 白皮沙拐枣>头状沙拐枣>东疆沙拐枣>中间锦鸡儿>多枝柽柳>狭叶锦鸡儿>甘蒙柽柳>荒漠锦鸡儿>细穗柽柳>多花柽柳;(4)在相同的环境条件下,乔木状沙拐枣、长穗柽柳、柠条锦鸡儿对该区的干旱环境有相对较强的适应能力。
英文摘要	The diurnal variations of photosynthetic characteristics of 14 species of drought-tolerant plants including Calligonum L.,Tamarix and Caragana Fabr. were studied in Ulanbuh Desert. The results showed that: (1) diurnal variations of net photosynthesis rates of 14 plants were double-peak curves, the peaks were at 10:00 and 16:00,respectively, and had obvious siesta phenomena of photosynthesis, and the impact factor was mainly stomatal change. Net photosynthesis rates decreased in the order of Caragana korshinskii Kom> Caragana intermedia Kuang et H. C. Fu> Calligonum arborescens Litv. > Tamarix hohenackeri Bunge>Tamarix leptostachys Bunge> Calligonum leucocladum (Schrenk) Bunge>calligonum east> Tamarix austromongolica Nakai > Caragana roborovskyi Kom. > Tamarix ramosissima Ledeb. > Calligonum caput-medusae Schrenk>Tamarix elongata Ledeb. >Caragana stenophylla Pojark. >Calligonum rubicundum Bge; (2) Calligonum L. and Tamarix transpiration rate changes were single-peak curves, the peaks were at 10:00 and 14:00,respectively, the species of the Caragana Fabr. transpiration rate was double-peak curves, the peaks were at 10:00 and 16:00, respectively. Transpiration rates decreased in the sequence of Tamarix hohenackeri Bunge>Tamarix leptostachys Bunge>Tamarix austromongolica Nakai> Caragana korshinskii Kom> Caragana roborovskyi Kom. >Caragana intermedia Kuang et H. C. Fu> Tamarix ramosissima Ledeb. > Calligonum leucocladum (Schrenk) Bunge> Tamarix elongata Ledeb. > Calligonum arborescens Litv. > Caragana stenophylla Pojark. > Calligonum caput-medusae Schrenk > calligonum east> Calligonum rubicundum Bge; (3) diurnal variations of water use efficiency were double- peak curves, water use efficiency in the morning was higher than in the afternoon, the peak appeared at 10:00,water use efficiency decreased in the order of Calligonum arborescens Litv. >Calligonum rubicundum Bge>Tamarix elongata Ledeb. >Caragana korshinskii Kom>Calligonum leucocladum (Schrenk) Bunge> Calligonum caput-medusae Schrenk>calligonum east>Caragana intermedia Kuang et H. C. Fu>Tamarix ramosissima Ledeb. > Caragana stenophylla Pojark. > Tamarix austromongolica Nakai > Caragana roborovskyi Kom. > Tamarix leptostachys Bunge> Tamarix hohenackeri Bunge; (4) under the same environment conditions, Calligonum arborescens Litv., Tamarix elongata Ledeb. and Caragana korshinskii Kom had relatively strong ability to adapt the arid environment.
