| 中文摘要: |
| 利用MODIS资料提取的归一化植被指数(NDVI)和地表温度(Ts),构建NDVI-Ts特征空间,依据该特征空间设计的温度植被旱情指数作为旱情指标,对青海省东部浅山农业区2004年7月上旬的旱情进行了动态监测,同时利用各气象台站实测的地面数据进行了验证,结果表明利用温度植被旱情指数(TVDI)法对青海高寒区进行干旱动态监测是可行的。 |
| 英文摘要: |
| Normalized Different Vegetation Index(NDVI) and Land Surface Temperature(Ts) were extracted from MODIS data,and were used to construct the NDVI-Ts space,from which the Temperature Vegetation Drought Index(TVDI) was obtained as drought index.The drought dynamic variation for the farming region of east shallow mountain in Qinghai in the first ten-day in July, 2004 was monitored,and compared with the simultaneously measured data of each observatory.The results indicated that it was feasible to monitor the drought dynamic variation in Qinghai high and cold area by using TVDI. |
