草方格是一种防风固沙、涵养水分的治沙方法，具有取材方便、施工简单、生态环保等特点。我国于1958年在中卫沙坡头创造了用草方格固定沙丘的技术，该技术成为治理沙漠的有效措施之一，在油气管道、沙漠公路等工程及阻挡沙化扩大等方面得到广泛应用。通过几十年的发展，草方格固沙技术现已成为成熟的固沙技术。通过对我国沙漠地区石油天然气管道工程常用的草方格固沙技术与土库曼斯坦的固沙技术的优缺点进行对比，介绍草方格固沙技术的优势、设计、施工和在国外类似工程建设中的应用前景。

Grass grid is a kind of wind prevention, sand fixation and water conservation methods and has such advantages as convenient material-adoption, simple construction, beneficial to ecological and environmental protection. In 1958,this sand fixation technology was firstly created in Zhongwei Shapotou District of northwest China and has become one of effective measures for desertification control from then on and is widely applied to sand fixation and water conservation in desert area oil and gas pipeline and highway engineering design. Through decades of development, the grass grid sand-fixation method has become a very mature sand-fixation technology. Conducted is contrastive analysis on advantages and disadvantages of the technology widely adopted in China's desert area oil and natural gas pipeline engineering design and sand-fixation technologies adopted in Turkmenistan and introduced is application prospect of such sand-fixation technology in future similar overseas engineering design.
