中文摘要：

以乌鲁木齐市达坂城长期大风区的优势种灌木霸王为研究对象，采用盆栽实验的方法，设置小风3 m/s、中风7 m/s、大风12 m/s以及对照（自然风速），选择持续吹风90 d的霸王叶采用石蜡切片法对其叶解剖结构特征进行比较观察。研究表明：与对照组（平均风速0.3 m/s）相比，在12 m/s风速下，霸王叶厚度增加了48%；在模拟大风、中风、小风（12、7和3 m/s）下，叶表皮厚度分别较对照增加了213%、117%和45%，栅栏组织排列紧密，其厚度分别增加了110%、70%和47%；在大风和中风（12和7 m/s）风速下，叶脉厚度分别增加了109%和76%。研究认为，模拟长期大风胁迫下，霸王叶通过增加叶片厚度即叶表皮层、栅栏组织及叶脉厚度来减少风对它的机械损害和水分散失。

英文摘要：

In this paper,Zygophyllum xanthoxylum which is dominant species shrub of Urumqi Dabancheng chronic high wind area was used as a study object.Through pot experiment,design three wind speed （light wind：3 m/s,medium wind 7 m/s,high wind：12 m/s）,on Zygophyllum xanthoxylum sustained wind treatment 90 d,leaf anatomical structures were analyzed with paraffin sectioning method.The results showed that,compared with control group（mean wind speed 0.3 m/s）,in the 12 m/s wind thickened of leaf thickness 48%;12 m/s,7 m/s and 3m/s wind increased cuticle thickness of 213%,117% and 45%,respectively;palisade tissue thickened of 110%,70% and 47%,respectively;12 m/s and 7 m/s vein thickened of 109% and 76%,respectively.In conclusion,under the chronic high wind simulation,Zygophyllum xanthoxylum reduce mechanical damage by respecting increased leaf thickness,cuticle thickness,palisade tissue and vein thickness,also control water loss.
