利用遥感图像对钏路泥沼的桤木（Alnus japonica）分布与周围土地利用之间的关系进行了空间评估。结果表明，钏路沼泽赤杨树面积的扩大是受到流域上游农业用地面积和下游洪水泛滥的影响。从农田流入钏路泥沼的土壤沉积物造成了严重的沉积，有利于桤木的生长。因此，桤木树的数量和密度都增加了。根据钏路沼泽赤杨树面积扩大的机制，对未来赤杨树的分布进行了预测，发现钏路沼泽的大片植被区将转变为有赤杨树的地区。
The relationship between alder (Alnus japonica) distribution and surrounding land use in Kushiro Mire was spatially assessed using remotely sensed imagery. From the result, it was found out that the expanding area of alder trees in Kushiro Mire was affected by the agricultural land area in the upper course of the river basin and flooding in the lower course of the river. The soil sediments flowing into the Kushiro Mire from the agricultural land resulted in heavy sedimentation that favors the growth of alder trees. Consequently, the number and density of alder trees has increased. The future distribution of alder trees was predicted based on the mechanism of expansion of the alder-tree area in Kushiro Mire, and it was found that large vegetation areas in Kushiro Mire will be changed to areas with alder trees.
