| 摘 要： | 高寒湖沼丘陵景观土壤详查方法技术是一个需要尽快解决的问题.景观区存在大量的风成沙,其优势粒级为-40～ 80目.选择3个试验区,探讨了土壤中元素的粒级分布特征、风化过程元素的地球化学性状,指出土壤中成矿元素迁移主要受到土壤风化程度和风成沙的约束,成矿元素迁移机制主要是机械分散和化学溶蚀.通过土壤详查示范测量,提出中高山区土壤详查方法以岩屑( 10目 )测量为主,中低山区适宜的土壤详查方法是残积土(-10～ 80目)测量. |
| 关 键 词： | 高寒湖沼丘陵 元素迁移机制 岩屑测量 残积土测量 |

| Abstract: | Detail soil survey technology for limnetic area in high-cold limnetic hills should rapidly be studied. There are a great of eolian sands distributing in this area and their main grain sections appear in -40 ~ +80 meshes. The grain features of trace elements in soil and geochemical characteristics of elements in weathering process of rocks have been studied in three areas. It is found that the migration mechanics of ore-forming elements in soils is mechanical dispersion and chemical facies transition restrained by weathering degree and eolian materials. Three illustration surveys showed that soil-debris (+10 mesh) survey in high-middle mountains or residual soil (-10~ +80 mesh) survey in middle-low mountains is suitable for limnetic area in high-cold limnetic hills. |
| Keywords: | high-cold limnetic hills element migration mechanics soil-debris survey residual soil survey |
