摘　　要：第二次全国土壤侵蚀遥感调查在精度、速度、可比性等方面都有了很大的进步 ,但由于受“土壤侵蚀”中一些理论和学术问题的制约 ,仍需要深入研究。笔者通过参加本次工作撰写此文对土壤侵蚀遥感调查学术上的一些问题 ,如土壤侵蚀的概念、坡耕地土壤侵蚀等级的判读和确定、土壤侵蚀强度和土壤侵蚀程度以及重力侵蚀、人为侵蚀等问题进行了探讨 。The second native soil erosion survey by remote sensing has made great progress in the precision, velocity and comparability. Due to the limit of some theoretic and academic problems, it is necessary to research more deeply. Having taken part in this work, the author argues about some academic problems of soil erosion survey by remote sensing in the paper, such as the concept of soil erosion, the interpretation and division of soil erosions grades on the hillside cultivated land, the intensity and degree of soil erosion, gravity erosion and human activation's erosion etc. It can be consulted by persons of the same field.
