摘要: 狮泉河盆地风成沙丘主要分布于盆地中西部, 风沙活动十分强烈, 对师泉河镇居民生产、生活造成了极为严重的危害。其成因是严酷的自然条件与不合理的人为活动共同的作用。通过对该区自然因素、人为因素及其相互作用的可能变化趋势分析, 风沙活动在今后至少是下世纪初以前, 仍将加速、加剧发展。在此基础上提出了风沙整治目标、技术措施与分区方案。

Abstract: According to our field investigation and wind tunnel esperiment, it is concluded that the sand dunes are mainly distributed in the centre and western part of Shiquanhe Basin and their frequent shifts, dominanted on Gobi plane, have seriously damaged the production and peole's life of the town. The wind-blowing sand was caused by harsh natural conditions and unreasonable human activities. Based on estimation of possible change tendency of the natural-human factors and their interaction, we predicted that the wind-blowing sand activities from now to the begining of next century,it would be more serious than today. The control objective, technical measures, and regionalization scheme are put forward on the basis of favourable and non-favourable conditions for wind-blowing sand control in the Basin.
