摘要

［目的］探清土壤侵蚀对土壤分布与特性的影响机制，为防治该地区的林下水土流失和土地退化提供科学依据。［方法］基于调查取样和分析测试获取的数据，采用统计和灰色关联度等方法分析红壤丘陵区马尾松林地侵蚀坡面的土壤特性。［结果］红壤丘陵区马尾松林地侵蚀坡面土壤养分相对较低，理化指标基本处于4级以下水平；红壤丘陵区马尾松林地侵蚀沟的土壤指标与坡面土壤的相应指标存在显著性差异，18个土壤指标中，侵蚀沟的土壤有10个指标显著优于坡面土壤的相应指标，侵蚀沟与土壤特性关联度更高，侵蚀沟土壤指标间的显著相关数量更少。［结论］红壤丘陵区马尾松林地的土壤侵蚀对林下土壤特性和分布产生了显著的影响，但侵蚀沟对土壤特性的影响机制尚需进一步研究。

Abstract

[Objective] To investigate the influences of soil erosion on the distribution and properties of soil in order to provide scientific basis for controlling soil erosion and land degradation in Pinus massoniana forestry.[Methods] Soil properties of eroded slope in P. massoniana forestry in the hilly red soil area of Southern China were studied based on statistics and the grey relational degree methods. The data was obtained by field surveying and sampling.[Results] Soil nutrients of the eroded slope were poor. Most of the soil physical and chemical indices were at or below level 4. There were significant differences in the soil index between soil on the slope and soil in the erosion gully. Among eighteen soil indices

ten soil indices of soil erosion gully were better than the corresponding indicators of soil on the slope. Compared with slope

the correlation between erosion gully and soil properties was higher

and the number of significant correlation indices of soil was less in erosion gully.[Conclusion] Soil erosion had a significant impact on the properties and distribution of soil on eroded slope in P. massoniana forest in the hilly red soil area of Southern China. Nevertheless

the mechanisms of the effect of erosion on soil properties needs to be further studied.
