湿地草本植物枯落物分解的影响因素

草本植物是湿地的主要植被类型之一，其枯落物是湿地有机物质的重要组成部分。本文概述了影响湿地草本植物枯落物分解的主要因素及研究进展，主要包括枯落物自身质量、生物因素、环境因素和人类活动与全球变化等。认为，枯落物质量是本质要素，生物是分解的主导因素，环境等外部因素起到重要作用。讨论了该领域有待深入研究的方向，指出要深入湿地枯落物分解机理的研究，加强多尺度、大环境梯度和多种影响因素的综合研究，加强全球变化对湿地枯落物分解的影响研究，增强实验方法研究等。

Factors affecting litter decomposition of wetland herbaceous macrophytes

Herbaceous macrophyte is a main vegetation type on wetland. Its litter decomposition is one of the key processes in the material cycling and energy flow of wetland ecosystem, and plays an important role in maintaining the functions of the ecosystem. This paper reviewed the research progress on the main factors affecting the litter decomposition of wetland herbaceous macrophytes, including the quality of litter itself, biotic and abiotic factors, and human activities, etc., and discussed the issues to be further studied. More attention should be paid on the mechanisms of litter decomposition, the effects of global climate change on the decomposition, and the approaches of related integrative and multi-scale research.
