| 摘 要： | 雅鲁藏布江中游河谷及其支流拉萨河和年楚河沿岸地带是西藏社会经济发展的中心,但也是遭受风沙灾害影响严重的区域.分布于雅鲁藏布江和拉萨河两岸,特别是贡嘎机场和拉萨市周边的河岸流动沙地,是本区土地沙漠化危害严重的区域.在对我国低海拔地区沙地飞播成功经验进行系统分析和总结的基础上,从降水、温度、光照、地形地貌和风况条件5个方面对西藏高寒河谷风沙化土地飞播可行性进行了研究.结果表明,雅鲁藏布江中游河谷雨热同季,光温水配合较好,对植物生长极为有利.同时5月底6月初播种期风向交换频繁,有利于种子自然覆沙.选择能够适应西藏高寒风沙化土地特殊生境条件的乡土植物种和解决种子播后的位移问题将是西藏高寒风沙化土地飞播试验成败的关键.

| Abstract: | The areas along the middle reaches of the Yarlung Zangbo River and its tributaries,the Lhasa River and the Nianchu River,are the center of social and economic development in Tibet,and also regions that are seriously affected by aeolian sands.The regions alongside the Yarlung Zangbo River and the Lhasa River,especially around the Gonggar Airport and Lhasa City,covered with rolling sand dunes are serious in hazard in Tibet.Based on systematic analysis and summarization of the successful experience of air-seed... |
