摘  要:
通过实地取样、试验及遥感影像分析,分析了河西走廊东部主要地表类型颗粒组成,估算了各地表类型表层土壤潜在尘源总量,分析了潜在尘源与2005年7月17日沙尘暴的关系。研究结果表明:绿洲耕作区易起尘颗粒百分含量最高,戈壁、灌丛、退化草原潜在尘源总量最大,农田次之、沙漠最少;该地区西部、西北部的沙尘源为7月17日沙尘暴提供了物质条件;增加上述地区的植被覆盖度可减轻当地沙尘暴危害。

摘  要:
Through investigation,test and remote sensing analysis,the paper analysed the pellet form of the main earth′s surface in the east part of Hexi Pasageway,primarily estimated the total quantity of the potential duststorm source,analysed the relationship between potential duststorm source and "2005·7·17" duststorm.The result indicted that:the oasis tillage area has the highest percentage of pellet which is easy to rise,the Gobi,bush,degenerated grasslands have the most potential duststorm source.The duststorm source in west,northwest part of this area provided material factor for "2005·7·17" duststorm.Increasing the vegetation coverage of the area above can alleviate the duststorm disaster.
