| 摘 要： | 采用叶面滞尘法测定了西藏5种常见园林植物白玉兰、女贞、白柳、北京杨和日本晚樱的滞尘能力。结果表明：不同种园林植物滞尘能力差异较大,5种园林植物滞尘能力的顺序为女贞〉白柳〉日本晚樱〉北京杨〉白玉兰。在北京杨、白玉兰、日本晚樱、白柳4种落叶树种中,白玉兰的滞尘能力最弱,而白柳的滞尘能力最大。白玉兰的树冠郁闭度最小,而白柳的树冠郁闭度最大。可见,滞尘能力的大小和园林植物的树冠郁闭度呈一定的正向相关性。

| Abstract: | The dust catching property of 5 gardening plants in Tibet were determined using the sluggish dust method of blade surface. The result showed that dust catching property of 5 gardening plants were markedly different： Ligustrum lucidum（0. 716 g·m^-2 ）〉Salix alba （0. 363 g. m-2 ）〉Prunus yedoensis （0. 279g. m-2 ）〉 Populus× beijingensis（0. 192 g. m-2 ）〉Magnolia denudate（0. 048g. m-2 ） ,the dust catching property of Magnolia denudate was the minimum and Salix alba was the maximum in four deciduous trees,tree-crown density of the former was small,the latter was big,so the dust catching property and tree-crown density of gardening plants had certain positive correlation. |
