摘要

摘要：南极海洋的苔藓库由一种或两种苔藓组成，其中Chorisodotum aciphyllum和Polytrichum strictum形成了3.4米厚、5500年树龄的泥炭库。它们可能代表了世界上最简单的泥炭形成系统，因此研究它们的动力学可以帮助理解泥炭地的总体动力学，特别是温带覆盖泥炭地的动力学。它们可以深入了解泥炭的生长、分解和压实平衡如何导致泥炭的形成，下坡爬行如何是垂直边缘和形成图案沼泽的原因，以及泥炭的侵蚀如何是一个自然过程。

The contribution of Antarctic moss peat to the understanding of global peatland processes

Abstract The moss banks of the Maritime Antarctic composed of one or both of the mosses Chorisodontium aciphyllum and Polytrichum strictum form peat banks up to 3.4 m thick and 5500 years of age. They represent perhaps the simplest peat-forming systems in the world, so studying their dynamics can help in the understanding of peatland dynamics generally, particularly those of temperate blanket peat. They can provide insights into how the balance of growth, decomposition and compaction of peat results in peat formation, how downhill creep can be the cause of both vertical edges and the creation of patterned bogs and how erosion of peat can be a natural process.

期刊介绍： Antarctic Science provides a truly international forum for the broad spread of studies that increasingly characterise scientific research in the Antarctic. Whilst emphasising interdisciplinary work, the journal publishes papers from environmental management to biodiversity, from volcanoes to icebergs, and from oceanography to the upper atmosphere. No other journal covers such a wide range of Antarctic scientific studies. The journal attracts papers from all countries currently undertaking Antarctic research. It publishes both review and data papers with no limits on length, two-page short notes on technical developments and recent discoveries, and book reviews. These, together with an editorial discussing broader aspects of science, provide a rich and varied mixture of items to interest researchers in all areas of science. There are no page charges, or charges for colour, to authors publishing in the Journal. One issue each year is normally devoted to a specific theme or papers from a major meeting.
