摘要

[目的]获取黄河源区代表性土壤剖面风成母质的发育年代，结合区域古环境记录，探讨母质形成的气候背景，为该区可持续发展提供科学依据。[方法]采用中颗粒（38~63 μm）石英单片再生剂量法，测定黄河源区10个土壤剖面底部风成母质层的光释光年代；利用Malvern 2000激光粒度仪测得土壤的粒度机械组成；采用重铬酸钾—硫酸消化法测定土壤的有机质含量。[结果]①该地区土壤平均粒径介于14～37 μm，以粉砂为主（体积约占85%）；有机质含量介于13.1～41.1 g/kg，平均含量为27.2 g/kg； ②黄河源区土壤母质层开始形成时间大多数集中在晚全新世，特别是近2 000 a； ③黄河源区土壤剖面平均厚度为（0.46±0.05） m，土层厚度较薄，风尘堆积速率达（16±0.07） m/ka。[结论]黄河源区现存土壤厚度较薄，有机碳储量较高；土壤主要是在相对干冷的晚全新世气候下发育的，发育模式以风尘加积型为主。

Abstract

[Objective] To obtain the optically simulated luminescence (OSL) age of parent material of the representative soil profile in the source region of the Yellow River

reveal the development and formation of parent material based on the paleoclimate records

in order to provide scientific basis for the soil conservation and sustainable development of the area.[Methods] The silt-sized (38~63 μm) quartz optically stimulated luminescence single-aliquot regenerative (SAR) dose protocol was used to obtain the OSL ages of parent material layer at the bottom of 10 different soil profiles. The soil particle size was measured by Malvern 2000.The content of soil organic matter was determined by potassium dichromate-sulfuric acid digestion.[Results] ① The soil was mainly composed of silt (account for 85%)

and the average grain size was ranged between 14 and 37 μm. The content of soil organic matter was between 13.1 and 41.1 g/kg

and the average value was 27.2 g/kg. ② Soil in the source area of the Yellow River mainly developed since late Holocene

especially since the near 2000 years. ③ In this region

the average thickness of soil profile was (0.46±0.05) m

and the average dust accumulation rate was (16±0.07) m/km2.[Conclusion] The remarkable characteristics of the modern soil in source area of the Yellow River included thin soil layer and relatively high storage of organic carbon. As a sequence

the formation and development of soils mainly occurred in in a relatively dry and cold climate condition of late Holocene

and the development model was mainly aeolian dust aggradation.
