摘要
以江西省生态公益林5种主要林分类型为研究对象,从土壤水分—物理性质、土壤化学性质方面对5种典型林分类型进行比较,并应用SPSS 18.0软件采用主成份分析法对各林分类型土壤性质进行综合分析评价,结果表明:针阔混交林的土壤具有较好的土壤渗透性,具有较强的持水能力,其土壤养分含量与其他林分相比也更高,采用主成分分析对各林分类型进行综合评价,土壤性质的综合排序为针阔混交林>竹林>阔叶混交林>针叶纯林>针叶混交林。
Soil moisture-physical properties and soil chemical properties were compared between the 5 types of ecological forest in Jiangxi Province, amt applied SPSS 18.0 software by using the principal component analysis method on soil properties of each stand type of comprehensive analysis and evaluation. The results showed that coniferous and broad-leaved mixed forest soil has better soil permeability and has strong water holding capacity, the soil nutrient content compared with other stands is also higher, using principal component analysis to conduct a comprehensive assessment of various forest types and soil properties in a comprehensive sort for mixed coniferous and broad-leaved forest 〉 bamboo forest 〉 mixed broad- leaved forest 〉 coniferous pure forest 〉 mixed coniferous forest.
