国道318线海竹段公路整改遥感选线研究

The Choosing Line Research on Highway's Repair and Modification by Remote Sensing Technique in Haizhu Segment of National Highway 318

国道 318线海子山 -竹巴笼段位于四川省西部与西藏自治区交界处 ,由于受印度板块强烈影响 ,地震频繁 ,导致该路段地质灾害频繁发生 ,严重影响着进藏物资的运输和当地经济的发展。经过遥感调查、分析 ,确定地质灾害的发育特征 ,从地质背景、地质灾害、生态环境、经济等方面进行综合比较 。

The segment from Haizishan to Zhoubalong in national highway 318 lies in the borderline of the western part of Sichuan province and Tibet Because of the extensive effect of Indian Plate movement,earthquakes often take place in this segment,which results in frequent geological disasters and affects goods transportation of Tibet and local economic development By remote sensing survey and analysis,the characteristics of these disasters are found Then,after such elements as geological background,geological disasters,environment,and economic are overall appraised,the optimal highway line is chosen
