| Abstract: | By imported the meteorological drought composite index(CI),the meteorological drought development since 2008 winter wheat sowing was analyzed because of the large-scale drought from 2008 winter wheat sowing to January 2009. Taking meteorological data from 1951 to 2008 of 113 meteorological stations and Jan.2009 of 65 automatic meteorological stations in Henan province as basic data,the different grades meteorological drought development and spatial distribution was analyzed.The drought resisting measure and... |
