| 摘 要： | 基于2005年和2006年AMSR-E（advanced microwave scanning radiometer-earth observingsystem）的亮温,计算了8个亮温比值作为候选干旱指数。假设反演出的AMSR-E Land3土壤湿度数据能反映地表干旱程度,候选干旱指数与土壤湿度的相关性分析即能显示哪一候选干旱指数较好。选择河北省3个站点,分析了相关性较好的干旱指数的年际变化,并利用该干旱指数研究了河北省2006年3月份的干旱分布,通过比较河北省136个观测站的同期降水距平百分率,表明该干旱指数具有一定的实用性。 |

| Abstract: | Eight brightness temperature ratios are calculated by using 2005 and 2006 AMSR-E（advanced microwave scanning radiometer-earth observing system） data to be the candidate drought indexes（DI）.Under the assumption that the retrieved AMSR-E Land3 soil moisture（AMSR-E Land3 SM） data could reproduce the extent of the soil drought,the best candidate DI is selected according to the correlation coefficients between candidate DI and SM data,then annual variation of the best DI is analyzed for 3 stations in Hebei province,and the spatial distribution of the DI in March 2006 is compared to that of precipitation abnormity percentage derived from 136 stations data in the same period.Results indicate that the DI is available. |
