包兰铁路沙坡头段沙害治理成效遥感监测研究

Research on the Result of Sand Disaster Control through Remote Sensing Monitor in Shapotou Section of Baolan Railway

摘要: 包兰铁路沙坡头段“五位一体”治沙方法建立至今，在阻止沙漠对包兰铁路的威胁方面成效显著，为包兰铁路的安全运营提供了大力保障。笔者通过结合1990至2015年的遥感数据，利用“3S”技术，对包兰铁路沙坡头段治沙成效进行量化研究，查清监测区内截止2015年底沙化土地类型和土地利用类型的面积及变化情况。掌握监测区域沙化现状及发展趋势。分析各种治理措施的效果并提出新的治理模式。

Abstract: The “five bands in one system” sand control method has been established so far in the Shapotou section of the Baolan Railway, and played in an important role in preventing the threat of the wind and sand disaster to the Baolan Railway, and provided a strong guarantee for the safe operation of the Baolan Railway. Based on the remote sensing data from 1990 to 2015, the author quantitatively researches the effectiveness of sand control using the “3S” technology, and aims to reflect the area changes of desertification land types and land use types in the monitoring area by the end of 2015 in the Shapotou section of the Baolan Railway. We hope to grasp the current situation and development trend of desertification in monitoring area, analyze the effect of various control measures and put forward new control mode.
