选择银杏、刺槐、水杉、柽柳、绒毛白蜡、白榆、小钻杨、中山杉、弗吉尼亚栎等9种树种，在东港地区土壤含盐量不同的立地条件下进行栽培试验，以期选择当地理想的抗盐树种。结果表明：土壤含盐量在＜0．16％和0．16％～0．30％的范围内，造林保存率和生长量都达到预想效果，土壤含盐量＞0．30％时，效果不佳，需要改土排水措施，才能达到效果。通过试验表明，刺槐、柽柳、绒毛白蜡、白榆、小钻杨是东港地区理想的抗盐树种。%Nine species (Ginkgo biloba ,Robinia pseudoacacia ,Metasequoia glyptostroboides ,Tamarix chinensis , Fraxinus velutina ,Ulmus pumila ,Populus× xiaozhuanica ,Ascendens mucronatum ,Quercus virginiana)were se‐lected to be planted in Donggang Region under site conditions with different soil salinity ,so as to select idea salt‐re‐sistant species .Result shows that the afforestation survival rate and growth reach desired effect while soil salinity in the range < 0 .16% and 0 .16‐0 .30% ;the effect is ineffective while soil salt content> 0 .30% ,adopting measures of improving soil and drainaging can obtain the effect .Experiments indicate that Robinia pseudoacacia , Tamarix chinensis ,Fraxinus velutina ,Ulmus pumila ,Populus× xiaozhuanicais the ideal salt‐resistant species in Donggang Region .
