摘要
对怀宁县红星江滩、东至县升金湖滩引种的不同树种、不同品系的生长情况进行了调查，应用聚类分析将江滩立地条件上９个树种的适应性划为５个等级：（杨树、柳树）、（池杉）、（枫杨、乌桕）、（水杉、江南桤木、圆柏）、（柳杉）；不同品系早期生长统计分析结果，杨树品系以１７、１４及６９、７２混系，柳树品系以１７２、９０３生长较好；另外，湖滩立地条件上林木生长不如江滩，只可适当营造池杉、柳树。
Based on growth analysis of different tree species and strains planted in beach land,a statistic method was employed to classify the 9 species into 5 groups:Poplar and Willow;Taxodium ascendens;Pterocarya stenoptera,Sapium sebiferum;Metasequonia glyptostroboides;Alnus trabeculosa;Sabina chinesis;Cryptomeria fortunei.The results of statistic analysis of early year growing showed that Poplar strains,such as 14,17 and 69,72;Willows hybrid,such as 172,903 were better compare to others,in addition,growth of three tree species,including Polar,Willow and Taxodium ascendens,is better in river beach than in lake beach,where is only suitable for Willow and Toxodium ascendens.
