灌溉水利用系数分析及其影响因素探讨

摘要

我国是一个水资源匮乏的国家，随着经济增长速度的加快，水资源短缺问题严重制约着我国农业的发展。为了有效地解决农业可持续用水问题，大力发展节水灌溉技术成为必然。因此，研究灌溉水利用系数和其影响因素意义重大。基于我国灌溉水利用系数测算分析方法，结合文成县灌溉水利用现状，建立了“首尾测算法”灌溉利用系数计算模型，并综合分析了灌区规模、灌溉类型、管理水平对灌溉系数的影响，希望为今后农业高效灌溉技术的发展提供帮助。%Our country is a country of scarcity , with the speeding up of economic growth , the serious problem of water shortage restricts the development of agriculture in our country.In order to effective-ly solve the problem of agricultural sustainable water , developing water saving irrigation technology become inevitable.Therefore, the research on irrigation water use coefficient and its influence factors is of great significance.Based on the irrigation water use coefficient measurement analysis method , combined with irrigation water utilization in wenzhou region , established a “fore and aft measurement method” irrigation utilization coefficient calculation model.And comprehensive analysis of the size of the irrigation area , irrigation type , the influence of the coefficient of the management level of irriga-tion.Hope for the future development of agricultural efficient irrigation technology to offer help.
