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。
採用葉麵滯塵法測定瞭西藏5種常見園林植物白玉蘭、女貞、白柳、北京楊和日本晚櫻的滯塵能力。結果錶明:不同種園林植物滯塵能力差異較大,5種園林植物滯塵能力的順序為女貞〉白柳〉日本晚櫻〉北京楊〉白玉蘭。在北京楊、白玉蘭、日本晚櫻、白柳4種落葉樹種中,白玉蘭的滯塵能力最弱,而白柳的滯塵能力最大。白玉蘭的樹冠鬱閉度最小,而白柳的樹冠鬱閉度最大。可見,滯塵能力的大小和園林植物的樹冠鬱閉度呈一定的正嚮相關性。

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.
