美国等国家已将遥感、ＧＩＳ技术广泛应用于水土流失动态监测与预报，并开发出基于物理过程的土壤侵蚀预报模型。中国在水土流失地面观测、遥感监测方面已取得许多成果，但在区域土壤侵蚀评价、预报模型开发方面，缺少系列化观测与统计数据，已有的坡面土壤侵蚀模型等在通用性、适用性方面还存在不少问题。当前急需解决的问题是建立水土流失监测与评价指标体系，开发评价模型系统，建立国家水土保持信息系统
The United States and other countries have applied remote sensing and GIS technology to the dynamic monitoring and prediction of soil and water loss and developed soil erosion prediction models based on physical processes. In China, many achievements have been made in the field of groundwater monitoring and remote sensing monitoring. However, in the area of soil erosion evaluation and prediction model development, there is a lack of series of observations and statistical data. The existing slope soil erosion models are of commonality and applicability There are still many problems. The current urgent problems to be solved are the establishment of an indicator system for soil and water loss monitoring and evaluation, the development of an evaluation model system, the establishment of a national soil and water conservation information system
