摘　　要：在太湖滩地用湿地松、美国白蜡、水杉、池杉和柳树（对照）进行了不同树种、不同区域、不同淹水期和不同淹水深度的耐水湿对比造林试验。在淹水深度20～60．5cm、连续淹水时间达40d时观察结果为：①湿地松和柳树（对照）的成活率分别为99．7％和99．5％；美国白蜡、水杉和池杉的成活率分别为19．5％，30．2％和31．1％。②在太湖滩地湿地松表现与柳树（对照）一样，生长势和生长量一切正常，湿地松为常绿树种，病虫害较少，从绿化、美化和景观考虑，建议湿地松作为太湖滩地造林树种之一，并建议作为我国太湖地区淡水森林湿地植被恢复与重建的的适生树种之一。In this study, silvicultural test on the Taihu beach among Fraxinus americana L,Metasequoia glyptostroboides Hu et Cheng, Taxodium ascendens. Brongn, and Salix babylonica was compared with slash pine （pinus elliottii） in different regions, flooding duration and depth of water. In the flooding depth of 20 -60. 5 cm, continuous observation of flooding up to 40d revealed that： （1） the survival rates of Slash pine and willows were 99. 7% and 99. 5% ; the survival rates of F. americana,M, glyptostroboides and T. ascendens were 19. 5% ,30. 2% and 31.1% ,（2） The fourth time zone in the lake beach area the performance of slash pine was like the willows. The growth potential and quantity were normal, and the color of leaves were emerald; and comparing to the willow, the obvious advantage of slash pine was that it was the evergreen species, and the resistance to the pests and diseases was higher. Considering of the afforestation, beautification and landscape, the slash pine was selected as afforestation species in the Taihu lake beaches. And it is suitable for the vegetation restoration and reconstruction of the freshwater wetland in Taihu Lake area.
