Title
The investigation of relationship between integrated surface drought index (ISDI) detected drought condition and crop yield
Abstract
Chosen the winter crop yield data from agro-meteorological sites and ISDI results during 2000-2009 in Mid-eastern China, the corresponding relationship between drought and winter crop yield was analyzed using confusion matrix and Kappa coefficient. The results shows that the high or low values of ISDI can reflect the crop yield reduction condition caused by the drought or flood; the normal values of ISDI can reflect the crop yield increasing and fluctuation in normal condition. ISDI monitored drought condition has obvious corresponding relationship with crop yield change. This also proved that ISDI can accurate monitor the drought events occurred during winter crop growing season.
