| 摘 要： | 文章介绍了遥感监测草场旱情的原理，提出了利用距平植被指数和干旱指数确定干旱区和干旱等级的方法。应用此方法评估1995年青海省牧区草场旱情，与农业气象旬报的旱情分析吻合较好。

| Abstract: | The principle of remote sensing of the drought in Qinghai pastoral areas is described,and a method of determining drought region and drought grade is advanced using anomaly vegetation index and drought index. By using this method the drought of Qinghai pastoral areas in 1995 was evaluated which coincided with the drought analysis made from meteorological dekad information. |
