摘要: 以塔克拉玛干西部别里库姆沙漠东部为研究区,利用实时动态控制系统(RTK)技术动态测量胡杨沙堆的基本形态特征,并通过手工钻井获取地下水相关数据,分析胡杨沙堆形态特征对地下水的响应.结果表明: 研究区胡杨沙堆各形态参数变化范围均较大;该区潜水由西、南和西南向东北渗透,整个区域的潜水埋藏深度变化范围为0.15~83.2 m;除长度和周长的极大值外,胡杨沙堆其余形态参数指标与潜水埋藏深度均呈负相关;胡杨沙堆体积主要分布在63.54~91.24 m3.

Abstract: By regarding the east of Birkum desert of the west of Taklimakan as research areas, the paper measured the basic morphological characteristics of Populus euphratica
nebkhas through realtime kinematics, got the relevant data of groundwater by manual drilling, and analyzed the response of emorphological characteristics of P. euphratica nebkhas to groundwater. The results showed that the change range of morphological parameters of P. euphratica nebkhas was large. Groundwater infiltrated the research areas from west, south and southwest to northwest and the depth of groundwater ranged from 0.15 m to 83.2 m. Except for the maximums of the length and circumference, the other morphological parameters of P. euphratica nebkhas had a negative relation with the depth of groundwater. The  volume of P. euphratica nebkhas was mainly in the range of 63.54-91.24 m3.
