北京市郊区现代农业节水灌溉技术的经济效益分析

Economic benefit of water saving irrigation techniques for modern agriculture in suburb of Beijing

在介绍北京市郊区现代农业节水灌溉技术发展状况的基础上,以北京市大兴区农业灌溉采用滴灌技术为例,依据农户种植经济作物的投入产出数据,运用统计分析方法和计量模型分析方法,对节水灌溉技术的经济效益进行了实证分析。结果表明:与传统灌溉方式相比,采用滴灌技术可以减轻劳动强度,提高作物的产值和净收益,但是,由于农户的灌溉思想传统、掌握先进技术的能力较低和技术的适应性差等原因,滴灌技术的节水效果不是很明显。

Based on an analysis of the development situation of water-saving irrigation techniques for modern agriculture in the suburb of Beijing,taking the drip irrigation for agricultural irrigation in Daxing district of Beijing as an example,an empirical analysis of economic benefit of the water saving irrigation techniques was performed by use of statistical methods and metrological models according to the input-output data of farmers’ cash crops. The results show that compared with the traditional irrigation techniques,the drip irrigation technique can reduce the labor intensity and raise the crop output and net income. However,owing to the causes such as the farmers’ traditional opinion,poor ability to master advanced techniques and poor technical adaptability,the efficiency of the water saving technique of drip irrigation is not obvious.
