【摘要】 在回顾国内外传统地面灌溉及滴灌条件下农田GSPAC系统响应规律、节水控盐的灌溉水管理措施、农田及区域水文循环模拟研究进展的基础上,提出了在干旱盐渍化灌区进行节水灌溉需结合区域特点将先进的灌水技术、农艺措施、高效的灌溉水管理措施和灌排技术结合形成灌溉调控新模式,并以内蒙古河套灌区为典型,分析了地下水膜下滴灌-引黄水补灌的空间和时间调控模式及其需要研究的科学问题和应解决的关键技术。更多还原

【Abstract】 The progresses in three aspects were reviewed,including the response rules of field GSPAC system under conditions of surface irrigation and drip irrigation,management measures for water-saving and salinity-controlling irrigation water,field and regional hydrologic cycle simulations throughout the world.Results indicated that when water-saving irrigation was adopted in arid and salinity irrigation districts,the regional characteristics should be considered combining the advanced irrigation technology,the agronomic measures,the highly efficient irrigation water management measures and the irrigation and drainage technology together to achieve the purpose of water-saving and salinity-controlling.With Hetao Irrigation District of Inner Mongolia as an example,the new regulation mode was analyzed,as well as the corresponding scientific problems and key technologies.更多还原
