| 摘 要： | 利用FY-3A/MERSI数据基于植被供水指数法(VSWI)对2010年夏季重庆地区干旱进行监测,并结合综合干旱指数CI,建立了新的拟合干旱指数(VSWIC)。反演结果与全市同期170个土壤墒情监测站的土壤湿度资料进行了对比。结果表明:FY-3A/MERSI卫星资料能够客观反映重庆地区旱情的空间分布和动态发展过程,植被供水指数和对应实地观测的10、20 cm土壤持水百分含量之间有较好的负相关关系,其中VSWI和10 cm深度处的土壤持水百分含量之间的相关关系更为稳定。利用FY-3A卫星资料进行重庆地区干旱监测是可行的。

| Abstract: | Drought status of Chongqing area was evaluated using FY-3A/MERSI satellite data based on vegetation supply water index(VSWI),and new fitting drought index(VSWIC)was established combining the CI index.To verify the monitoring accuracy of VSWIC in Chongqing City severe drought,the soil moisture data in 170 soil moisture monitoring stations in the same period were used.Results showed that FY-3A/MERSI satelite date could reflect the space distridution and dynamic developing process of drought in Chongqing area.... |
