基于投影寻踪模型的灌溉水利用系数影响因子分析

摘要

Analysis on impact factor of water efficiency of irrigation has a great significance on improving water efficiency of irrigation,promoting agriculture sustainable development and ensuring food security.Projection pursuit model is first applied to analysis on impact factor of water efficiency of irrigation.In this paper ,it ana-lyzes the impact factor of water efficiency of irrigation of 5 typical sub-areas at a big irrigation area ,which plays a certain guiding role on promoting water efficiency of irrigation.%灌溉水利用系数影响因子分析对提高灌溉水利用系数, 促进农业的可持续发展, 保障粮食安全具有重要意义. 本文首次将投影寻踪模型应用于灌溉水利用系数影响因子分析中来, 并对某大型灌区5个典型子灌片灌溉水利用系数影响因子进行分析, 对提高灌溉水利用系数具有一定的指导作用.
