摘  要:
为治理土壤侵蚀和防止水土流失,该研究基于遥感和ULSE模型,该研究基于遥感和ULSE模型,定量评价了延吉市2006年和2016年的土壤侵蚀量及其空间分布。结果表明:延吉市的土壤侵蚀在自然因素方面主要受坡度影响,人为因素方面主要受人们对各土地利用类型间面积转变的影响。2016年土壤侵蚀状况主要集中在轻度侵蚀和微量侵蚀;近10年来,微量侵蚀面积在增加,而其他侵蚀类型的侵蚀面积均在减少;侵蚀最严重的位置集中在8°~25°的斜坡和陡坡;旱地侵蚀较严重。该研究对坡耕地的改造及水土保持等方面提供一定的理论参考。

摘  要:
In order to control soil erosion and prevent soil erosion, based on remote sensing and ulse model, this study quantitatively evaluated the amount and spatial distribution of soil erosion in Yanji City in 2006 and 2016. The results show that the soil erosion in Yanji city is mainly affected by the slope in natural factors, and the human factors are mainly affected by the change of the area between different land use types. In 2016, soil erosion mainly focused on mild erosion and micro erosion; in recent 10 years, the area of micro erosion has increased, while that of other erosion types have decreased; the most serious erosion is located on 8 °-25 ° slopes and steep slopes; dry land erosion is more serious, this study provides certain scientific basis for the transformation of slope farmland and water and soil conservation.
