SYSTEM FOR DEDUCTING AGRICULTURAL DROUGHT INDEX AND METHOD THEREFOR

摘要

The present invention relates to a system for deriving an agricultural drought index and a method for deriving an agricultural drought index using the same, and more particularly, to a new drought index method for estimating plant water availability in a soil by taking into consideration not only precipitation but also ground runoff, And a method for deriving the agricultural drought index using the system. The present invention can provide a more sophisticated and reliable drought index considering the precipitation as well as the ground runoff and the evapotranspiration. The present invention can increase the availability of research on the spatial distribution of agricultural drought by providing detailed water drought diagnosis according to crop and soil types, providing water management information according to drought diagnosis, and the like. In addition, the present invention can be utilized not only for monitoring agriculture drought, but also for predicting further aging or drought.;
