摘要
灌区的经济效益体现在农作物经过灌溉后所提高的产量 (或产值 )上 ,而农作物产量 (或产值 )的提高是农业措施和灌溉措施综合作用的结果 ,因而灌溉地区分摊系数的确定是决定灌溉效益大小的关键 本文采用统计的方法 ,根据灌区农作物历年产量的变化确定灌溉效益的分摊系数 ,并对山东引黄灌区的灌溉效益分摊系数进行分析 。
The economic benefit of irrigated area is reflected in the increased yield of grains after being irrigated Both the measures taken in the agriculture and that in the irrigation play an important role in the process of increasing the irrigated areas yield It is the key problem to determine divvy coefficient of the irrigated area In this paper, a statistical method has been adopted, in which the divvy coefficientof the irrigated benefit is determined according to the variation of annual yields of this area In the meantime time, we have studied the divvy coefficient of irrigated benefit about the Yellow River irrigated areas in Shandong Province, which in turn verifies the reliability and the validity of this method
