| Abstract: | The principle of anomalies of vegetation index monitoring drought was discussed,and the composite method of anomalies of vegetation index was introduced.Anomalies of vegetation index monitoring crops drought were analyzed to determine the level of drought.Combination of the meteorological data,such as precipitation,temperature and so on,the trend and cause of agricultural drought,and response to temperature and precipitation with anomalies of vegetation index were analyzed. |
