摘要:
以山东省临沂市四种典型土地利用方式为例,分析不同土地利用方式对土壤养分及肥力的影响.结果表明:不同土地利用方式对有机质(OM)含量具有显著影响,而对pH、全磷(TP)、全氮(TN)、全钾(TK)和土壤颗粒组成无显著影响.不同土地利用方式土壤OM含量由高到低顺序为:水田>未利用地>林地>旱地;TN含量由高到低顺序为:未利用地>林地>水田>旱地;TP含量由高到低顺序为:未利用地>旱地>林地>水田;TK含量由高到低顺序为:林地>水田>旱地>未利用地.相关分析表明,旱地各养分之间的相关系数要大于水田、林地和未利用地,不同土地利用方式对TP和TN之间的相关系数无影响.主成分分析表明,旱地、水田、林地和未利用地综合肥力指标F值大小顺序为:水田(0.86)>林地(0.78)>旱地(0.51)>未利用地(0.43).
Abstract:
4 typical land use of Linyi Shandong Province were taken as a case study. The influence of different land uses on soil nutrients and fertility was analyzed. The result indicated that different land use had significant effect on organic matter (OM), but had no significant effect on pH, total phosphorus (TP), total nitrogen (TN), total kalium (TK) and particle composition. The order of contents of OM in different land use types was paddy field >unutilized land>forest land>dry land. The order of content of TN in different land use types was unutilized land>forest land>paddy field>dry land. The order of content of TP in different land use types was unutilized land>dry land>forest land>paddy field. The order of content of TK in different land use types was forest land>paddy field>dry land>unutilized land. Correlation analysis indicated that the correlation coefficient among different nutrients of dry land was larger than paddy field, forest land and unutilized land. Different land use types had no significant effect on the relativity between TP and TN. The component analysis indicated that the order of the comprehensive fertility index F of dry land, paddy field, forest land and unutilized land was paddy field(0.86)>forest land(0.78)>dry land(0.51)>unutilized land(0.43).
