摘要

[目的]对青海省木里江仓煤矿区高寒湿地腐殖质层形成过程进行分析，为当地矿区与渣山的植被恢复提供科学依据。[方法]应用沉积学、光释光（OSL）年代学以及土壤营养学对江仓和木里地区高寒湿地表层土壤剖面进行了较为全面的研究。[结果]①江仓剖面由冲积扇砾石层、黄土层、泥炭层和腐殖质层组成，腐殖质层形成年代为1.7±0.1 ka，木里高寒湿地剖面由基岩风化层和腐殖质层组成，腐殖质层形成年代为2.0±0.2 ka。②江仓和木里两剖面的腐殖质层中有机碳、全氮、碱解氮、全磷等含量较高。[结论]该地区高寒湿地腐殖质层的形成时间至少是2 000 a，形成过程十分缓慢，草原植被生长依赖于含量较高的土壤有机质。后续的渣山植被恢复工作需要因地制宜，通过提高土壤厚度、肥力等方法来缩短土壤形成的时间。

Abstract

[Objective] The formation age

process and soil nutrients of wetland in Muli-Jiangcang coal mine area in Northeastern Qinghai-Tibet Plateau were studied in order to provide scientific basis for vegetation restoration of open-pit coal mine spoil heaps.[Methods] The strata analysis

optically stimulated luminescence(OSL) dating method and soil nutriology were applied to study the forming progresses of humus layers in alpine wetlands.[Results] ① The Jiangcang coal mine area was composed of alluvial gravels

loess

peat sediment

and humus layers

which had an OSL age of 1.7±0.1 ka. The Muli coal mine area was composed of weathered crust and humus layers which had the ages of 2.0±0.2 ka. ② There were high contents of organic matter

total nitrogen

available nitrogen

and total phosphorus in the humus layers.[Conclusion] The forming age of the humus layers of the wetlands underwent two thousand years at least

indicating a long evolution history. The plants of the wetlands depended on the abundant nutrients of humus layers. It is suggested to adjust measures to local conditions

and increase soil thickness and soil fertility as soon in order to recover the vegetation on coal mine spoil heaps.
