| 摘 要： | 在植被指数相同的条件下,地面肤面温度可用于对土壤旱情的监测。通过植被指数--地面肤面温度特征空间分析了利用遥感进行旱情监测的原理,将传感器温度作为地面肤面温度,对干旱指数的计算进行了详细论述。利用栾城县的Landsat7 ETM+卫星数据进行了旱情监测与分析。

| Abstract: | Land surface temperature can be used in the inspection of drought in the same vegetation index. In this paper, the principle of drought inspection using remote sensor was analyzed through the characteristic space of vegetation index and land surface temperature, land surface temperature was replaced with sensor temperature, the method of calculation drought index was discussed in detail. Using Landsat7 ETM~+ sensor data in Luancheng County, the situation of drought was obtained and analyzed. |

| Keywords: | Vegetation index Land surface temperature Drought inspection Landsat7 ETM~+ sensor data |
