| 摘要: |
| 【目的】解决常规固定式滴灌溉系统的单位投资成本相对较高、配套设备的重复利用率偏低、维护管理不便等实际问题。【方法】采用定型化设计、标准化配套和通用化操作的结构设计，研制了具有设备集成度高、成本投资少、功能实用、操作简单、易于推广应用等特点的抗旱用轻型滴灌系统。根据轻型滴灌系统的组成和应用特点，结合农业生产实际需求，研究和优化了系统的总体结构，并进行了成套系统的直接投资、间接投资和年运行费、折旧费等计算，比较分析系统应用后的节本、减灾、增收等效益，并运用投资静态评价指标的计算方法，分析了抗旱用轻型滴灌系统的投资回收年限和益本比。【结果】轻型滴灌系统的最大控制灌溉面积为0.67 hm2，总投资1 730元/套，年均运行总费用537.50元/hm2，比常规固定式滴灌系统节约成本45.3%，促进作物产量提高8%～13%，用户整体经济效益提高约25%～30%，投资回收年限为0.71 a，益本比高达1.40。【结论】从经济上充分说明轻型滴灌系统投资合理，能够满足普通农户的实际接受能力，并具有较好的经济效益。 |

| Abstract: |
| 【Objective】 The fixed drip irrigation system has some shortcomings including high costs, difficult for reuse, inconvenient maintenance and management. To overcome these problems, a light drip irrigation system for emergent use in drought fighting was developed. The purpose of this paper is to analyze its financially viability.【Method】 The analysis was based on the structure of the system. The costs considered in the analysis included direct and indirect costs, the operation cost and its devaluation; the benefits considered included the save in costs compared with the fixed system, increased profits due to amelioration of the adverse impact of the drought, and the consequent increased income. The calculation was based on the method of investment static index. 【Result】The maximum area of the light drip irrigation system controlled was 0.67 hm2, the total investment was 1 730 yuan/set, the total annual operation cost was 537.50 yuan/hm2, and the system cost was lower 45.3% than that of the regular fixed drip irrigation system, the crop yield was raised by 8%～13%, the total economic benefit of the users was raised about 25%～30%, the investment in the light drip irrigation system could be returned after 0.71 years, and the benefit-cost ratio was 1.40. The system hence had a good economic benefit. 【Conclusion】 The light drip irrigation system is financially viable and acceptable by farmers. Its high benefit-cost ratio means that it provides a vial irrigation technique for emergent use in drought fighting. |
