中文摘要：

在分析甘肃省中东部黄土高原旱作区当前干旱灾害和农业生产现状的基础上，进一步分析了干旱灾害和农业生产模式以及二者的互作效应对农田系统抵御干旱灾害能力的影响。认为抗旱减灾农作制度必须以科学轮作的作物体系、耕地质量保育和自然降水高效利用的栽培技术体系为支撑点。只有建立基于多样化的作物体系、秸秆还田、科学轮作、垄沟种植、二元覆盖和少免耕技术的农作制度，协调农田生产和生态之间的关系，才能够实现甘肃省中东部黄土高原旱作农田水土资源的可持续利用，达到抗旱救灾和农田生产力持续提高的目标。

英文摘要：

The situation of drought and agricultural production on the arid area of the Loess Plateau in the middle and east Gansu Province was expatiated, and the effects of the interaction between drought and agronomic planting structure on drought-resistant ability of cropland system were also analyzed. The results showed that the drought-resistant farming system must be based on the rational crop system, the farmland conservation system and efficient rainwater utilization, including diverse crop system, straw-returning, rational crop rotation, ridge-furrow planting, dual mulching and minimum tillage and no-tillage, to harmonize the relationship between agricultural yield and ecology, and then to use water and soil resources sustainably on the area, and furthermore, to achieve the target of drought-resistance and continuous increment of agricultural yield.
