摘　　要：以黄土高原沟壑区的长武塬为研究对象,根据黄土高原沟壑区干旱频繁发生的特点,在发展传统农业抗旱技术的基础上,调整土地利用结构,应用抗旱品种及与之相配套农业耕作技术和轮作种植技术,发展窑窖集水,滴灌、渗灌、微灌等抗旱节水灌溉技术,建立现代抗旱减灾农业技术体系.为发展减灾农业提供科学依据.Characters of drought were analyzed in Changwu dryland in the Loess Gully Region to establish the agricultural droughtfight and calamitydiminished technology on the base of traditional technology.The structure of land utilization should be rectified,droughtfight species and together with agricultural plow and crop rotation technology be applied,droughtfight and watersaving irrigation technology of watergathered in kiln cellar,drip irrigation microirrigation and so on be developed,thus scientific evidence to develop calamitydiminished agriculture will be formed.
