微润灌技术在荒山绿化工程中应用的经济分析

Economic Analysis of Application of Micro Irrigation in Greening of Barren Hills

微润灌溉是一种利用半透膜原理研制而成的微润灌溉系统。该灌溉系统具有低能耗、高节水的特征。本文利用技术方案经济评价方法,对微润灌、喷灌和滴灌技术经济指标进行分析和对比;同时,作者还结合了节水灌溉技术经济指标的特点,创新使用盈亏平衡点指标来验证分析结果。结果显示,虽然微润灌技术尚处于推广阶段,但其存在巨大的应用潜力和经济效益,在徐州市荒山绿化治理中应用前景广阔。

Micro irrigation is a kind of micro irrigation system developed with semipermeable membrane principle. The irrigation system has the characteristics of low energy consumption and high water saving. The economic evaluation method for the technology scheme were used in this paper, the technical and economic indexes of micro irrigation, sprinkler irrigation and drip irrigation were analyzed and compared. At the same time, the author also combined all the characteristics of economic indexes, and with the innovative use of the balance point of profit and loss index, the analysis results were verified. The results showed that, although the micro irrigation technology is still in the promotion stage, it has great application potential and economic benefits. In Xuzhou, its application in treatment of barren hills has a good application prospect.
