| 摘 要： | 青海省大柴旦双口山地区属于我国干旱荒漠戈壁特殊景观区之一,具典型大陆荒漠气候特征。依托2010年"青海绿梁山—双口山矿产远景调查"项目,开展了干旱荒漠戈壁特殊景观区1∶5万区域化探最佳采样粒度、采样密度等有效性方法实验。通过野外采样、室内分析及数据处理,确定了适合此特殊景观区的1∶5万水系沉积物测量采样方法技术:采样密度为6～8点/km2,采样粒级在-20～+60目,较为经济合理,技术上可行。 |
| 关 键 词： | 双口山 荒漠戈壁景观地区 水系沉积物测量 采样密度 采样粒度 |

| Abstract: | The Shuangkoushan area of Dachaidan in Qinghai Province is one of arid desert and gobi land- scape areas, with the typical climatical characteristics of continental desert. Mainly relying on the project ＂Qinghai Luliangshan-Shuangkou Shan Mining Vision Survey＂, we carried out the effective method tests about theoptimum sampling grain size and sampling density to regional geochemical in arid desert and gobi landscape area. Through field sampling, laboratory analysis and data processing, we determined the sam- piing methods of 1 ： 50000 stream sediment survey for this special landscape area. The reasonable sam- piing density is 6-8 samples per square kilometer, and the reasonable sampling grain size is --20-＋ 60 mesh. |
