摘要

采用样方法

调查了福建省长汀县红壤侵蚀区马尾松林下芒萁的生物量、覆盖度和高度生长特征

并与地形、土壤养分和土壤侵蚀强度等环境因子进行相关性分析。结果表明

不同坡向上的芒萁生物量差异较为明显

其中位于东坡的样地生物量最大(1 967.65g/m

)

位于南坡的生物量最小(1 230.28g/m

)。各样地的芒萁覆盖度和高度随着坡位的升高而逐渐降低。芒萁总生物量、覆盖度和高度与有机质和全氮呈显著的正相关性。土壤侵蚀程度与芒萁的生物量、覆盖度和高度都达到极显著的负相关性。该地区芒萁的生长主要受侵蚀程度、土壤有机质和全氮等因素的影响。芒萁对控制水土保持有着重要的作用

因而可作为南方红壤侵蚀区水土保持与生态修复的先锋植被。

Abstract

The biomass

coverage and height of Disranopteris dichotoma

as well as topography

soil nutrients and soil erosion degree in Changting County

Fujian Province

were investigated using quadrat methods.The differences of the biomass were evident in different slope directions.The total biomass for the quadrats on east slope was with the maximum of 1 967.65g/m2 and for the quadrats on south slope

with the minimum of 1 230.28g/m2.The coverage and height decreased with increased slope position.The total biomass

coverage and height were positively correlated with soil organic matter and total nitrogen.Soil erosion degree was significantly negatively correlated with the biomass

coverage and height.The Dicranopteris dichotoma growth was apparently influenced by soil erosion degree

soil organic matter and total nitrogen.Dicranopteris dichotoma plays some important roles in controlling soil and water loss and therefore

it can be used as pioneer vegetation in soil and water conservation and ecological restoration of the study area.
