Multistage policy-making processes and optimization of water development along both sides of yumen section of Lanzhou- Xinjiang railway were studied by means of dynamic planning process. With total cost and maximum net benefit of channel system as objective functions, mathematical model , optimization channeling route and distrbution scheme were established respectively in light of local natural conditions and statistical data. The mathematical model and calculation method have proved to be feasible through 15 years of practices.

本文应用动态规划研究兰新线玉门段铁路两侧水资源开发多阶段决策过程的最优化问题,采用整个输水系统的总费用最小和净效益最大分别作为目标函数,并分别建立数学模型,结合当地的自然条件和统计资料,选择了是最佳引水路线方案,并对水资源进行科学而合理地分配。经过15年来的运用实践证明:这些数学模型和计算方法是行之有效的。

The relation between amount of Mownsand and wind Velocity were studied by 7means of self-developed sand-taped instrument in three years started from 1985 at Turpan-Y urgou section of Lanzhou-Xinjiang railway.

1985年开始连续三年,在新疆吐(鲁番)—鱼(儿沟)段,用自制的集沙仪对多次大风进行了风速与集沙量关系的观测,得到的经验公式为: Q1=1.92e~0.31(V—u) 此式与附近气象站风速资料推算之全年输沙量值极为接近。

The Lanzhou-Xinjiang railway stretches a length of 1050km m gobi region and frequently suffers from wind -sand stream hazards , especially in the 30-km section between Xiangyanghe and reclaimed areain yumen of Gansu province. The major reason is that the distruction of ground surface during the construction of railway in gobi region exposed tne umderlying sand source to wind erosion and causes wind - sand flow hazards to the railway.

The Lanzhou-Xinjiang railway stretches a length of 1050km m gobi region and frequently suffers from wind -sand stream hazards , especially in the 30-km section between Xiangyanghe and reclaimed areain yumen of Gansu province. The major reason is that the distruction of ground surface during the construction of railway in gobi region exposed tne umderlying sand source to wind erosion and causes wind - sand flow hazards to the railway. In the past twenty tears such protective measures as "with forest as sandbreaK " ,"blocking the sand outside the forest and removing sand nearby the railway " have been adopted and achieved great successes.

兰新铁路通过戈壁地区线路长达1050km,铁路营建后受到戈壁风沙流危害,兰铁玉门段向阳湖、垦场区间长约30公里,危害尤烈。产生的原因是戈壁铁路修建中,破坏地表使蕴藏的沙粒失去掩蔽,成为风沙的来源和加强风沙流活动,并在铁路上形成积沙。经二十多年努力,采取“以林养障(沙障)”,“林外截沙源,路内消积沙”的防护措施,取得了成效。
