摘要

选择山西省中阳县车鸣峪林场4种典型防护林为研究对象

通过静水崩解试验测定土壤抗蚀指数并对其与土壤基本理化性质的关系进行了研究。结果表明

不同防护林土壤抗蚀性能存在明显差异

土壤抗蚀指数表现为:落叶松白桦混交林>白桦纯林>落叶松纯林>辽东栎纯林。土壤抗蚀指数随土层深度的增加而减小

表现为0-20cm土层抗蚀指数是20-40cm土层的2~5倍。土壤抗蚀指数随浸水时间的增加而减小

呈三次多项式函数关系。土壤抗蚀性指数与容重、粒径>0.25mm土壤水稳性团聚体、有机质含量和全氮含量呈显著正相关关系

与其基本理化性质存在一定的线性关系。

Abstract

Taking 4 typical shelterbelts in Chemingyu Forestry Station

Zhongyang County

Shanxi Province as studying subjects

the article discussed the relationship between soil anti-erosion ability and soil physical and chemical characteristics through measuring the soil anti-erosion index by the experiments of static soil collapse.The results indicated that:the soil anti-erosion ability varied apparently with the types of shelterbelt

among which the order of soil anti-erosion indices is as follows:combines foresty of Larix spp. and Betula platyhylla Suk. >Betula platyhylla Suk.>Larix spp>Quercus liaotungensisKoidz.;Anti-erosion ability decreases with the increase of soil depth and time of water soaking.Soil anti-erosion indices in up-per 20 centimeters are 2-5 times as these under 20 centimeters and present a cubic polynomial relation with time of soaking.The amount of soil bulk density

water-stable aggregate(>0.25 mm)

organic matter and total nitrogen is of significantly relations with anti erosiorrindex and some kind of lineal relation with its physical and chemical characteristics.
