本文利用遥感技术对吉林省水蚀情况进行调查,通过卫星影象目视解释85个土壤水蚀图斑资料,运用线性模型理论,对吉林省各地区的水蚀规律进行了综合研究,得到了下垫面各因素对水蚀量指标的侵蚀模数、侵蚀深度和侵蚀速率的正规方程解,找出了影响吉林省水蚀量的主导因素。通过分析揭示了下垫面各因素对水蚀量的影响程度,为吉林省水土保持综合治理提供了理论基础。
In this paper, we investigate the water erosion in Jilin Province by using remote sensing technology. Through the visual interpretation of 85 images of soil water erosion by satellite imagery, using the linear model theory, the water erosion laws in different areas of Jilin Province are comprehensively studied. The underlying surface Various factors on the water erosion indicators erosion modulus, erosion depth and erosion rate of the normal equation solution to identify the main factors that affect the amount of water erosion in Jilin Province. By analyzing and revealing the impact of various factors on water erosion, it provides a theoretical basis for comprehensive management of soil and water conservation in Jilin Province.
