摘要: 以四川省理县凉台沟3种不同林型(冷杉纯林、桦木纯林和冷桦混交林)0~40 cm土层为研究对象,探讨不同林型的土壤理化性质变化规律,旨在为该区的人工林可持续发展提供理论依据。研究结果表明:(1)土壤含水量随土层的加深而逐渐减少,其大小冷桦混交林 > 桦木纯林 > 冷杉纯林。(2)各林型土壤机械组成颗粒含量的变化均是砂粒 > 粉粒 > 粘粒;土壤中砂粒含量为冷杉纯林 > 桦木纯林 > 冷桦混交林,而粗粉粒、细粉粒和粘粒则呈现相反的趋势。(3)土壤pH值介于5.3~5.8之间,3种林型pH值随土层深度的增加而增大,但差异均不显著,其中冷杉林的pH值最低,混交林的pH值最高;(4)3种林型土壤有机质、全N、有效P和速效K均随土层深度的增加而减少,呈现明显的"表聚"现象,其含量表现为:桦木纯林 > 冷桦混交林 > 冷杉纯林

Abstract: In this paper,taking the soil layer of zero to 4 cm thickness of 3 different forest types(pure fir forest,pure birch forest and mixed forest of birch and fir,in Liangtaigou of Lixian County of Sichuan as the research object,researches were conducted on the change rule of soil physical and chemical properties of the different forest types in order to provide theoretical basis for the sustainable development of artificial forests. The results of the study showed that (1) their soil water content decreased with the increase of the soil depth:mixed forest > pure birch forest > pure fir forest (2) changes of particle content in soil mechanical composition of different forest types were as follows:sand > silt > clay,and the sand content in the soil:pure fir forest > pure birch forest > mixed forest of birch and fir,and yet coarse silt,fine silt and clay displayed an opposite trend (3) The soil pH value was between 5.3~5.8,pH value of 3 forest types increased with the increasing of soil depth,but there was no significant difference in the pH value. Among them,the pH value of fir forest was the lowest and the pH value of mixed forest was the highest; (4) 3 kinds of soil organic matter,total N,available P and available K all decreased with the increase of the soil depth,showing obvious "accumulation" phenomenon. Their contents were as follows:pure birch forest > mixed forest of birch and fir > pure fir forest.
