中文摘要：
阐述了宁夏保护性耕作的发展概况，总结了平罗县近年来保护性耕作技术模式的应用情况，并深入分析了其实施效益。研究结果表明：保护性耕作技术在防治土壤盐碱化、改良盐碱土，技术节水、减少水分蒸发，改变地表径流、减少土壤流失，减少农田扬沙、抑制沙尘暴，改善土壤结构、提高土壤有机质含量，增加微生物量，调节土壤温度等生态保护方面取得了显著效果；该项技术的推广应用还能提高作物产量、减少生产工序、节约生产成本、提高农民收入、促进区域经济社会发展。提出了科学推广保护性耕作技术模式、提高生态经济效益的对策建议。
英文摘要：
The paper expounded the general developmental situation of the protective cultivation in Ningxia, summarized the application status of the protective cultivation technique model, and deeply analyzed its implementation benefits. The results showed that the protective cultivation technique model had obvious effects on controlling soil salinization, improving saline soil, saving water, reducing moisture evaporation, decreasing soil surface runoff and soil erosion, reducing farmland dust, inhibiting dust storm, improving soil structure, increasing the content of soil organic matter and microorganism biomass, and adjusting the soil temperature. The application and popularization of this technique model also could raise the crop productivity, reduce production processes, save production cost, increase the peasants＇ income, and promote the regional economic and social development. The author put forward some countermeasures for popularizing the protective cultivation technique model and enhancing ecological and economic benefits.
