- 摘要:
- 西气东输工程是我国"十五"期间的四大重点建设工程之一,也是国家实施西部大开发战略的标志性工程.西气东输工程是独特的大型线状建设工程.西气东输施工条件复杂,途经甘肃省12个县、市,多种地貌类型,工程建设将大面积扰动地表和产生大量弃土弃渣,水土流失的类型,成因非常复杂.沿途包括典型的干旱气候风力侵蚀区和半干旱水-风复合侵蚀区,尤以风力侵蚀为主.管道工程对土壤的影响主要在管道地面开挖阶段,在干旱荒漠区管道开挖建设对土壤的影响主要表现为对土壤地表的扰动破坏,该区域的地表稳定层是长期自然选择的结果,一旦遭到破坏,很容易造成风蚀.从水土保持学的角度.阐述西气东输工程开发的重要性,分析了风蚀现状,提出了防治对策.
- Abstract:
- 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.
