摘要
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,the conditions of water erosion are investigated with remote sensingtechnique. By using the information of 85 water erosion pictures of decipher and adopting Linearmodel theory,the water erosion law in Jilin Province are studied comprehensively. The normal e-quation solutions of grourd cover factors to the erosion intensity indexes(erosive modulus,erosiondepth and erosion rate)are made. The leading factors to affect water erosion amount and the influ-ence value of every factor to water erosion has ben found out. These provide some theoreticalbases for the mangement of soil and water conservation of Jilin Ptovince.
