Spatial Variability of Irrigation Efficiency of Nationwide Large-scale Irrigation Systems
Abstract：Data of Irrigation Efficiency (IE) of nationwide typical large-scale irrigation systems trom g006 to 2009 were collected and their spatial variability was calculated using geostatistical analysis. The results of spatial variability analysis indicated that the autocorrelation extent of IE was about 650 km and structural factors played a major role, which meant that anisotropic property was not obvious.
