- 摘要:
- 土壤微形态研究的任务是利用显微镜观察和分析土壤微结构，这对重建土壤形成时的环境背景具有重要意义。初步分析了青海民和县喇家遗址内外的土壤微形态。在喇家遗址内的土壤微结构中发现有铁质胶膜，表明了局部较强的淋溶作用。喇家遗址外的土壤微结构中孔隙较多，出现了大量暗色矿物，并呈现一定程度的定向排列特征，显示了成壤过程中受到生物的扰动和水流作用的影响。
- Abstract:
- The task of soil micromorphological study is to analyse soil microstructure through microscope, which is very important for environmental reconstruction during soil formation.In this paper, soil micromorphology characteristics in Lajia site, Minhe county, Qinghai Province was observed and preliminarily analyzed.Ferric membrane was found in soil microstructure inside Lajia site, indicates local intense eluviation.Many voids, together with dark suites that present directional characteristic to some extent were found in soil microstructure outside Lajia site, which suggests that this area was influenced by biodisturbance and current during Qijia cultural period.
