辽宁省泥质海岸防护林对土壤理化性质的影响
|
摘要
为了分析不同林分类型的防护林对土壤理化性质的影响,以辽宁省泥质海岸5种不同类型防护林为研究对象,分析并得出了不同林分类型的防护林对土壤速效氮、速效磷、pH值、总孔隙度、体积含水量、土壤密度的影响,结果表明:防护林不同类型林分对土壤的理论性质有显著影响,其中速效氮含量的依次为刺槐纯林>辽宁杨纯林>小胡杨+紫穗槐混交林>刺槐+杨树混交林>小胡杨纯林,刺槐纯林和辽宁杨纯林与空白对照组存在显著差异;对土壤pH值影响的程度由大至小排列为辽宁杨纯林>小胡杨+紫穗槐混交林>小胡杨纯林>刺槐+杨树混交林>刺槐纯林,各林分与对照组均存在极其显著差异;对土壤速效磷含量影响的程度由大至小排列为辽宁杨纯林>小胡杨+紫穗槐混交林>小胡杨纯林>刺槐+杨树混交林>刺槐纯林,与对照组均存在极其显著影响,以辽宁杨纯林、小胡杨+紫穗槐混交林、小胡杨纯林的影响最为显著;对土壤孔隙度影响的程度由大至小排列为刺槐纯林>辽宁杨纯林>小胡杨纯林>刺槐+杨树混交林>小胡杨+紫穗槐混交林;刺槐+杨树混交林、辽宁杨纯林对土壤含水量的影响最为显著;刺槐纯林、辽宁杨纯林、小胡杨纯林对土壤密度影响效果最为显著。
In order to analyze the influence of different forest types on soil physical & chemical properties, five different types of forest protection on the muddy coast of Liaoning Province were studied. The effects of different forest types on soil available nitrogen, phosphorus, pH, total porosity, volume water content & soil density were analyzed. Result shows that different forest types have a significant impact on the theoretical properties of soil;among them, the order of the rapid nitrogen content is Robinia pseudoacacia pure forest > Populus maximowiczii pure forest> Populus simonii ×P. euphratica + Amorpha fruticosa mixed forest > Robinia pseudoacacia and Populus maximowiczii mixed forest> Populus simonii ×P. euphratica pure forest.There are significant differences between Robinia acacia pure forest and Populus maximowiczii pure forest & control group. The degree of influence on soil pH ranges from large to small rows is Populus maximowiczii pure forest > Populus simonii ×P. euphratica + Amorpha fruticosa mixed forest> Populus simonii ×P. euphratica pure forest> Robinia pseudoacacia + Populus maximowiczii mixed forest > Robinia pseudoacacia pure forest.There are significant differences between the forest and control groups. In terms of the degree of influence on soil available phosphorus content, Populus maximowiczii pure forest,Populus simonii ×P. euphratica + Amorpha fruticosa mixed forest and Populus simonii ×P. euphratica pure forest have most effects.The degree of influence on soil porosity ranges from large to small rows is Robinia pseudoacacia pure forest> Populus maximowiczii pure forest > Populus simonii ×P. euphratica pure forest> Robinia pseudoacacia + Populus maximowiczii mixed forest> Populus simonii ×P. euphratica + Amorpha fruticosa mixed forest; the effects of Robinia pseudoacacia and Populus maximowiczii mixed forest and Populus maximowiczii pure forest have most significant effects on soil water content. The effects of Robinia pseudoacacia pure forest, Populus maximowiczii & Populus simonii ×P. euphratica pure forest have most significant effect on soil density.
