Abstract:Research purposes:The analysis and research were made and done on the composition mechanisms of the sand - stabilization belt system and the sand-resistant belt system,on the the conditions of sand protection with project(machinery) and plant,on the determination of the protection width,on the plant selection and arrangement principle and on the feeding and irrigation conditions.The allocation requirements of the persons for the maintenance works in later stage was given out. The measures for sand protection were presented.The trend of the sand protection with plant was introduced.
Research conclusions:(1) When the rainfall is less than 160 mm and the groundwater can not meet the irrigation requirement,the sand protection with the project ( machinery) should adopted.When the rainfall is from 160 to 280mm,the sand protection with the project should be used along with the plant and small irrigation. When the rainfall is bigger than 280mm,it is unnecessary to conduct small irrigation,but needs pouring water on the plant root. ( 2) The plant protection of trees and shrubbery belt should be arranged with intervals,and the tree spacing should be 2 m×3 m and the shrubbery spacing should be 2 m×1 m or 2 m×1.5 m.3 The corresponding specifications of grid and the topography should be adopted along with some sand - protection barriers to the sand protection with the project. The branch or earthwork grid should be 1 m × 1 m and the downsand height should be 2-3 m. In the far sight situation,one or two sand-protection barrier should be used with height of above 3m,but in no far sight situation,the two or three sand-protection barriers should be used.(4) If the included angle between the alignment of a road or railway with the wind direction is less than 30 degree,the protective width should be L* sin β according to the current code ( β is the included angle between the wind direction and the track) .(5) The film catchment,organic plant and fungi hatching cover can be used for the sand protection.(6) The sand protection should be combined with the tourism and economic development.In the early stage,the investment can increase appropriately.
