阔叶红松林4种演替阶段不同土层深度磷组分的特征
Characteristics of Soil Phosphorus Fractions at Different Depths Across 4 Successional Stages in a Broadleaved Pinus koraiensis Forest
摘要
Abstract
In order to explore the differences of soil phosphorus fractions in different forest community suc-cession stages and different soil depths in broad-leaved Pinus koraiensis forest,the soil of broad-leaved P.ko-raiensis forest(natural Betula costata secondary forest,secondary broad-leaved forest,secondary coniferous and broad-leaved mixed forest and original broad-leaved P.koraiensis forest)in 4 different succession stages in Less-er Khingan Range was taken as the object to analyze the effects of different succession stages and different soil depths(0-10,10-20,20-40 cm)on soil phosphorus fractions(total phosphorus,available phosphorus,organic phosphorus and inorganic phosphorus).The findings demonstrate that with the progress of forest community suc-cession,soil total phosphorus,available phosphorus,organic phosphorus,inorganic phosphorus,active organic phosphorus,moderately active organic phosphorus,Al-P and Fe-P showed a trend of first decreasing and then in-creasing,while moderately stable organic phosphorus,highly stable organic phosphorus,O-P and Ca-P showed a trend of first increasing and then decreasing.The contents of available phosphorus,moderately active organic phosphorus and Fe-P did not decrease significantly with the change of soil layer,and the content of Ca-P in-creased with the deepening of soil layer.The contents of total phosphorus,organic phosphorus,inorganic phos-phorus,active organic phosphorus,moderately stable organic phosphorus,highly stable organic phosphorus,Al-P and O-P decreased with the deepening of soil layer.关键词
