| 摘 要： | 地表温度-归一化植被指数(Ts-NDVI)特征空间干旱监测方法易受到监测期地表湿度、植被覆盖状况和卫星观测质量的影响,导致特征空间干、湿边不稳定,在基于长时间、大范围卫星观测资料的基础上对Ts-NDVI特征空间方法进行改进,将其称为通用特征空间方法.首先基于某观测时段,单独构建每年基于该单一年份单一时段卫星观测数据的T... |

| Abstract: | The land surface temperature(Ts)-Normalized difference vegetation index(NDVI) space based drought monitoring is vulnerable to the soil moisture,vegetation cover and satellite observation state,which makes the dry edge and wet edge of Ts-NDVI space unstable,so it is likely to bring more errors in the drought monitoring.The paper develops a method named the general Ts-NDVI space using the multi-year satellite data in the same period to resolve the instability of the Ts-NDVI space.Firstly,the primary Ts-NDVI s... |
