本文在分析比较了目前几种土壤侵蚀问题的监测研究方法的前提下，针对该问题研究引入遥感和ＧＩＳ工具后产生的新问题，以云南盘龙河流域下垫面土壤侵蚀状况分级制图任务为例，提出了基于多因子分析及其信息融合技术的土壤侵蚀分级制图方法，通过反复实验研究，取得了较理想的研究成果。同时也证明了该技术途径的适用范围和可行性。
Based on the analysis and comparison of several current monitoring methods of soil erosion, this paper studies the new problems caused by the introduction of remote sensing and GIS tools for this problem. The grading mapping of underlying soil erosion in Panlonghe Basin of Yunnan For example, a hierarchical soil mapping method based on multi-factor analysis and its information fusion technology is proposed. Through repeated experimental studies, the ideal results have been obtained. At the same time, it also proves the scope and feasibility of this technical approach.
