摘　　要：沙枣和大果沙枣无论是成林还是幼林,沙枣的流胶率和流胶量都要低于大果沙枣。生长在暖温带南疆的沙枣,流胶虽然低于寒冷的中温带北疆,但流胶量却大于北疆。虽然沙枣成林的数量巨大,但因缺乏产品型的产业替代进口的阿拉伯胶,要做到从单林转换到资源林的位置上来还需努力。The rate and quantity of gum output of Elaeagnus agustifolia were lower than E. moorariftii regardless of mature or young forest. The rate of gum output of E. agustifolia grown in southern part of Xinjiang with warm climate were lower than that grown in northern part of Xinjiang with cold climate. However, it was opposite that the gum output of E. agustifolia was more appropriate to be a resource forest because of large number of mature forest. Due to lack of product-based industries of E. angustifolia gum, it could be a breakthrough if a single individual of E. agustifolia can really be converted to a resource forest.
