Effect of Wind Erosion on the West-East Pipe Project (Gansu)

China's West-East Pipe Project is one of the four key construction projects in '10th Five-Year Plan' period,and also is one of the national landmark projects under the implementation of the western development strategy.Project is a unique line of large construction projects,which has the complex construction conditions,via 12 counties and cities of Gansu Province,a variety of landscape types.The project constructions will greatly disturb surface and produce a large amount of spoil disposal Java.The type and mechanism of soil and water loss is a complex problem.Along the way,there exit the typical arid climate wind erosion and semi-arid areas of water-wind composite erosion,especially the wind erosion.Impact of Pipeline Engineering major on the soil surface is mainly in the pipeline excavation phase.In the arid desert area,impact of pipeline construction on soil excavation is mostly in the soil surface damage.This region's stable surface layer is a long-term result of the natural selection.Once damaged, it is likely to result in erosion.From the perspective of soil and water conservation,the importance of the project development is explained,the status of erosion is analyzed and the control measures are proposed.
