碧峰峡森林土壤性状研究

碧峰峡不仅是旅游景点,还是多学科研究的天然“实验室”,地处雅安亚热带区,原始森林植被保护完好,土壤垂直分布明显,地质现象复杂,也是大熊猫、金丝猴出没之地。经研究结果：土壤呈酸性,自然肥力高．经相关分析结果：土壤有机质含量和ＣＥＣ等有关理化特性的相关性,较物理性粘粒与ＣＥＣ间更加显著。

A Study of the Characters of Forest Soil in the Bifeng Gorge

Bifeng Gorse is not only a tour place but also a natural"laboratory"for many subjects.Ithas subtropical moist climate,well-proctected original plant cover,apparent vertical distribution ofsoils and complicate geology.Giant pandas and golden monkeys are often found here.The resultsobtained from the study have shown that the soil is tinged with acidity and has a high matural fertility and that the relationship between the CEC and organic matter content of the soil is more significant than that between the CEC and physical clay content.
