摘要: 摘 要:在安徽升金湖自然保护区水陆过渡带种植15种木本植物,测试各树种的耐水性。结果表明:1)本土树种枫香、垂柳、金丝垂柳、中山杉、乌桕、水杉、江南桤木和枫杨成活率分别为98.9%, 98.3%, 91.3%,51.2%, 50.0%, 7.3%, 4.0%和1.8%; 引进树种美洲黑杨、池杉、彩叶杞柳、日本甜柿、落羽杉、美国山核桃和水紫树成活率分别为 79.7%, 72.4%, 56.8%, 55.7%, 34.6%,15.8% 和 6.3%;2)垂柳、枫香、美洲黑杨和池杉在持续淹水第60~90天(淹水深度为81.7 cm),其淹水成活率分别为100%,100%,100%和 95.2%;金丝垂柳和中山杉在持续淹水第60~90天(淹水深度65.9 cm),其成活率分别为 97.7% 和 93.8%。初步筛选出垂柳、枫香、金丝垂柳、池杉、美洲黑杨和中山杉这 6 个树种作为我国长江中下游地区淡水森林湿地植被恢复和重建的适生树种。

Abstract: Abstract: Forested wetlands are rare in China because most of them have been destroyed by the long history of human disturbances. Consequently, reconstruction and restoration of freshwater forested wetlands lack reference sites for community composition. We investigated tree species to lerance to water logging for a wetland restoration project at the Shengjin Lake Nature Reserve of Anhui Province. A total of 15 woody species were tested in the annual flooding of low lakeshore areas. The survival rate of the seedlings was examined after 14 months since the woody species were planted. The inundation survival rate was 98.9%, 98.3%, 91.3%, 51.2%, 50.0%, 7.3%, 4.0%, 1.8% for native species ( Liquidamba formosa, Salix babylonica, Salix×aureopendula,Taxodium ascendens×T.mucronatum, Sapium sebiferum, Metasequoia glyptostroboides, Alnus trabeculosa, and Pterocarya stenoptera ), respectively, and 79.7%, 72.4%, 56.8%, 55.7%, 34.6%,15.8%, 6.3% for the exotic species (Populus deltoie, Taxodium ascendens, Salix integra, Diospyros kaki, Taxodium distichum, Carya illinoensis, and Nyssa aquatica ), respectively. The inundation survival rate was 100%, 100%, 100% and 95.2% for the species of Salix babylonica, Liquidamba formosana, Populus deltoe and Taxodium ascendens under flooding for 60~90 d with a average 81.7 cm depth water, 97.7% and 93.8% for Salix×aureo-pendula and Taxodiam ascendensx×T.mucronctum under flooding for 60~90 d with 65.9 cm depth water. Six suitable species were selected, they are Salix×babylonica, Liquidamba formosana, Salix aureo-pendula, Taxodium ascendens, Populux deltoids, Taxodium distichum and Taxodium ascendens×T.mucronatum for the vegetation restoration and reconstruction of the forested freshwater wetland in Shengjin Lake Nature Reserve.
