| Abstract: | The meaning and calculation method of irrigation water quota were analyzed in this paper. On the basis of data of irrigation water quota of rice in 30 representative counties of Yunnan province, the authors used Kriging method and inverse distance weighted method to plot the isoline map of irrigation water quota of rice in Yunnan province. Comparison between the two methods showed that Kriging method gave better results than inverse distance weighted method. |
