近年来,阿勒泰地区天然林和人工林逐步开始遭受鼠害,常把幼树和大树地下的根茎部位咬断,造成地面树干枯萎死。被啃食的树木较严重时可干枯死亡,并引起大面积的毁林现象,使草地退化、水土流失,影响生态建设。介绍了鼠害的危害、成灾情况、发生规律、综合防治等,为尽快控制其危害,提出了防治建议。
In recent years, the natural forests and plantations in the Aletai region gradually began to suffer from rodent pests, often severing the root and stem parts of saplings and large trees underground, causing the trunk of the ground to wither and die. When grazed trees are more serious, they may die dead and cause deforestation on a large scale, degenerating grasslands, soil erosion and ecological construction. The harmful effects of rodent pests, the disaster situation, the regularity of occurrence and the comprehensive prevention and control were introduced. In order to control the damage as soon as possible, some suggestions for prevention and treatment were put forward.
