十八站林业局位于大兴安岭东北坡。境内河流较多,山势低缓,沟谷宽阔,大面积的沼泽地到处可见。全局沼泽地总面积近28万公顷,占全局经营面积的115.4万公顷的1/4左右。20年来,由于呼玛河流域森林的大量砍伐和连年火灾损毁,导致地下水位上升,地处下游的十八站林业局,其沼泽地日显扩大之趋势。为扩大森林面积,必须大力开展沼泽地改造。 Eighteen Station Forestry Bureau is located in the northeast slope of Daxinganling. The territory of the river more, low mountain, wide valleys, large swamps can be seen everywhere. The total area of ​​the global wetlands is nearly 280,000 hectares, accounting for about 1/4 of the 1.144 million hectares of the total area under business operation. In the past 20 years, due to the massive deforestation in the Huma River Basin and successive years of fire damage, groundwater levels have risen and the ebb and marshlands have been gradually expanding in the past 18 years. To expand the forest area, we must vigorously carry out the transformation of wetlands.
