2007年6月至2008年9月,多次对平朔矿区排土场复垦林地发生的沙棘木蠹蛾和红缘天牛进行了实地调查.结果表明,平朔矿区排土场复垦林地的林龄有的已有10多年,由于受土层厚度和水分的影响,有的沙棘长势提早发生变化,在这个演替的过程中,沙棘木蠹蛾和红缘天牛的发生达到严重的程度.在5年以上的幼龄林,也开始有中轻度为害的迹象,应加以重视和采取防控措施.随着林龄的提高,沙棘主株受危害的程度明显增加.干旱的立地条件使沙棘的长势提前衰退是造成该矿区沙棘木蠹蛾和红缘天牛大发生的重要原因.

Holcocerus hippophaecolus and Asias halodendri were investigated many times in reclamation woodland of Pingshuo Mine, Shanxi, during June, 2007 to September, 2008. Some trees were old than ten years and due to the influence of the thickness of soil horizon and moisture content, the growth vigor of some sea backthern changed. In the process of succession, H hippophaecolus and A halodendri had infected seriously. There appeared moderate or slight damage in trees of age over five years. Attention and control measures is needed. Along with the increased age of trees, damager of sea backthern increased. Dry situation in site land caused growth vigor decline ahead of schedule is an important reason for serious infection of H hippophaecolus and A halodendri.
