摘要:
通过对新疆策勒流动沙丘地、半流动沙丘地、砾质戈壁不同类型流动沙丘进行观测，研究了不同下垫面不同类型流动沙丘年运移速度、方向及其规律，为沙丘运移规律及保护绿洲生态安全提供理论依据。结果表明：沙漠—绿洲过渡带流动和半流动沙丘年平均前移距离为4.76～12.92 m，半流动沙丘比流动沙丘前移速度明显减小，沙丘移动方向为东南东（99.82°—115.48°）。砾质戈壁2 m高新月形流动沙丘年移动距离为9.37 m，年移动方向为东南东（105.1°）。0.9 m高盾状沙丘年运移距离19.15 m，移动方向为东南东（93.77°），流动沙丘移动方向与年合成输沙势方向东南东（108°）基本一致，沙丘高度与运移速度呈二次函数反比关系。如果不采取有效的防沙措施，流动沙丘将会对策勒绿洲产生潜在的入侵威胁。
Abstract:
Through field observation of shifting sand dunes on surfaces of shifting sandy land, semi-shifting sandy land and gravel Gobi desert, we investigated the migration velocity, direction and regularity of shifting sand dunes and semi-shifting sand dunes in different landscape types within a year in order to provide the theory basis for dune migration law and protection of oasis ecosystem. The results showed that annual migration distances of shifting and semi-shifting sand dunes on Cele oasis-desert ecotone were between 4.76 m and 12.92 m, the migration speeds of semi-shifting dunes decreased significantly compared with the shifting sand dunes. Moving direction of sand dunes was ESE (99.82°—115.48°). Annual migration distance of crescent dune on Gravel Gobi desert with 2 m high was 9.37 m, the moving direction was ESE (105.1°). The annual migration distance of shield dune with 0.9 m high was 19.15 m, the moving direction was ESE (93.77°), and the movement direction of shifting sand dunes was primarily in accord with resultant sand transporting potential direction for ESE (108°) within a year. Dune height and migration velocity followed the polynomial function inversely proportional relationship. If the effective prevention measures are not taken, shifting sand dunes will pose potential invasion threat to Cele oasis.
