本文依据课题组多年研究提出的水平梯田耕地质量提升技术及作物产量监测结果，对宁南山区水平梯田经济性进行了分析评价。研究结果表明：水平梯田建设的投资回收年限为3.9年，建设第一年至第五年，产投比分别为0.62、0.75、0.92、1.03、1.12，经济效益显著。本研究摸清了坡改梯工程建设的效益，为政府相关部门决策提供理论支撑，对保持区域持续发展意义重大。
Based on the quality improvement technology and crop yield monitoring results of horizontal terraced farmland proposed by the research team over the years, this paper analyzes and evaluates the economics of horizontal terraces in Southern Ningxia. The research results show that: the pay-back period for the construction of horizontal terraces is 3.9 years. From the first to the fifth year of construction, the production-to-investment ratio is 0.62, 0.75, 0.92, 1.03, 1.12. The economic benefits of horizontal terrace construction are significant. This study finds out the benefits of slope farmland to terrace, provides theoretical support for government decision-making, it is of great significance to maintain the sustainable development of the region.
