Rainwater harvesting and use is a direction for sustainable development of dryland farming in the hill and gully area of southern Ningxia Hui Autonomous Region.According to the area's natural，social and economic characteristics，and in combination with the spread of applied agricultural technology，five kinds of integrated models of rainwater harvesting and use technology are set forth.These include:(I)integrated use model of rainwater collected in watersheds;(2)grassland and forestry construction use model of rainwater collected form slope land;(3)field farmland irrigation supply use model of rainwater collected from road surfaces;(4)courtyard guard plant use model of rainwater collected from roof and court;and(5)high efficiency dry field use model of rainwater collected from microcollection engineering.The benefits of the models are analyzed from results obtained at the national demonstration district of rainwater harvesting and use.which is located in Wangwa demonstration district of Pengyang County in southern Ningxia region of China.
