Abstract

Abstract: In this paper, an aggregative index has been defined in order to describe the comprehensive fea-tures of agroclimatic resources efficiency in Inner Mongolia.Based on the calculation of meteorologicaLand grain yield data of the 10 years ( 1991-2000), we analyzed heat and rainfalLutilization efficiency distribution of main grain crops at 29 represent stations.T he result shows that the aggregative indexes of grain crops, spring wheat and maize are higher in eastern part than that in centra-Lwestern region except the irrigation areas of Yellow Riv-er in Inner Mongolia, while the index of millet in the centra-Lwestern part is higher than that in the eastern part.

Key words: Agroclimatic resource, Aggregative index, Distribution feature, Utilization efficiency
