Remote sensing, with the merit of large information capacity, huge observation scope, high accuracy and speed, has become the main means of regional desertification monitoring and evaluation.
近些年来，遥感以其信息量大、观测范围广、精度高、数据更新速度快等优点，已成为区域荒漠化监测与评价的主要手段。
After the desertification monitoring individually in 1994 and 1999, we completely mastered the dynamic change of desertification surrounding the area of Qinghai Lake.
经1994年、1999年两次荒漠化监测，全面的掌握了青海湖及其周围荒漠化土地变化动态。
