| Abstract: | The irrigated agricuIture in arid regions may be called oasis agrictiIture,a particularhuman landscape in arid regions. The tnean annual precipitation in the middle Yellow Riverbasin is 350-500mm ,and it is sufficient to meet the agricultural need for one crop a yearin general.However,becaues the yearly rainfall in this region is highly concentrated,andthe land surface is dissected to a grest degree,the effective water available to crops isoften iri shortage. To maintain the stable and sustainable development of agricuIture,theartificial oasis construction, the check dam system for intercepting sediment and buildingland should be conducted in this region. The three basic conditions including water,topography and soils are all favorable to the artificial oasis construction. Study shows that 25000 check dams can be built,and after the completion,3.5-4.0million mu of land can be obtained,where 400-800 million kg of grain may be producedannually. However,to make the agricuItural environment sustainable,the followingshould be taken into account:1.the careful planning for check dam system;2. multi-purpose check dam system aiming at flood protection, sediment interceptlon,land buildingand grain production;3.the cotintermeastires for saliiiization and water-logging;and 4,the regular maintenance to keep the check dams stable. |
