The Research on the Pattern of Precipitation in Hebei Agricultural Regions

Abstract:

Using Visual Basic, in the range of seven irrigation managing regions in Hebei, the research analyzed annual and quarterly features of precipitation in the recent 51 years, and using Mann-Kendall Non-Parametric Test, analyzed annual and quarterly trend of precipitation of every agricultral region. The research finds that there are large differences between seven agricultural regions, except Inland River Region, precipitation in the other regions shows decreasing trend each year. The research about seasonal precipitation shows that Inland River Region has more precipitation in autumn, but other regions have more precipitation in summer; the precipitation increases in spring in all agricultral regions, but decreases in summer except Inland River Region, increases in autumn except Yanshan Hill Region, and increases in winter in all the agricultural regions.
