| 摘 要： | 以嘉陵江源头风景区7种林型(锐齿栎林、红桦林、油松林、华山松林、巴山冷杉林、针阔混交林及灌木林)土壤为研究对象,通过对林地土壤不同层次pH、有机质及主要养分含量的测定,分析不同林型下土壤肥力的差异状况。结果表明,华山松林、油松林和针阔混交林的土壤趋于中性,锐齿栎林、红桦林、灌木林的土壤趋于弱酸性,而巴山冷杉林的土壤呈酸性。随土壤深度增加,土壤pH升高,土壤有机质、全氮、全磷、碱解氮、有效磷含量均呈下降趋势。土壤综合肥力优劣为华山松林<油松林<针阔混交林<锐齿栎林<灌木林<巴山冷杉林<红桦林。

| Abstract: | Based on analysis of soil pH,the content of organic matter and main nutrient at the different levels of soil under seven different forest types(Quercus aliena BI.var.acuteserrate,Betula albo-sinensis,Pinus tabulaeformis,Pinus armandii,Abies fargesii,coniferous and broad-leaved mixed forest,shrub forest)in Jialing river of source,this paper studied on soil fertility of different forest types.The result showed that the soil in Pinus armandii,Pinus tabulaeformis and coniferous and broad-leaved mixed forest wer... |
