| Abstract: | In the paper,by using the method of incidence clustering,the index system for the frangibility zoning of agricultural drought in Hu'nan Province have been established.This paper applied the near method to set up the mathematic model and carried out the zoning study for the frangibility of agricultural drought of 97 frangibility.The zoning result has shown that there were 11 extremely serious frangible regions,23 serious ones,27 under serious ones,20 general ones and 16 light ones. |
