中文摘要：

干旱缺水与水土流失并存是制约黄土高原经济发展的两大瓶颈性因素.集雨补灌农业作为雨水利用的更高发展阶段,更加强调了从时间和空间2个方面对有限雨水资源实施主动调控与利用.大量研究与实践证明,集雨补灌农业不仅是黄土高原不可缺少的水资源开发利用形式,也是黄土高原水土保持工程技术体系的重要组成部分,更是黄土高原旱地农业持续发展的一种综合模式和战略性措施,是对旱地农业的进一步继承和发展.另外,具有工程化、科技化、规模化内涵的集雨补灌农业也已经成为现代节水农业技术体系的重要研究内容之一.黄土高原集雨补灌农业研究的深度和广度将会持续深入,其技术发展更加依赖于高新技术的支撑与应用.

英文摘要：

Drought and soil erosion are the two major obstacles to restrict economic development in the Loess Plateau of China. As a high stage for rainwater utilization, it emphasized the active regulation and utilization of rainwater in spatial location and time distribution. Rainwater catching for supplemental irrigation is not only an indispensable utilizing form of water resources, but also an important component of soil and water conservation technology system; even the strategic measure and comprehensive development model of sustainable arid land agriculture development in the Loess Plateau, and further inheritance and development of arid land agriculture. In addition, supplemental irrigation of catching rainwater for agriculture has also become one of important research field for modern water saving agriculture technology system. The depth and width of rainwater harvesting for supplemental irrigation will sustainably further; and its technological development will more depend on the support and application of high-technology.
