摘要
以文峪河上游河岸林为例,分析了河岸林与相邻高地林林下土壤的理化性质。研究结果显示,河岸林土壤含水量、速效磷和速效钾含量均高于相邻高地林;河岸林土壤有机质和全氮含量低于相邻高地林。不同类型河岸林和相邻高地林土壤含水量差异均达到极显著,土壤有机质含量均差异显著,土壤酸碱度差异均不显著。河岸林与相邻高地林土壤全氮和有机质含量呈极显著正相关(r=0.946 4)。土壤含水量、速效磷和速效钾含量在不同林型河岸林和高地林下的分布格局不同。
Comparison of soil properties under riparian forest and adjacent upland forest in upstream of Wenyu watershed was analyzed. The results indicated that soil moisture, contents of available phosphorous and available kalium under riparian forest were generally more than that in adjacent upland forest, while contents of soil organic matter and total nitrogen were less than that in adjacent upland forest. Soil moisture and content of organic matter in different riparian forests had sig- nificant difference, but there was no significant difference among the soil pH. Content of soil organic matter had significant- ly positive correlation with total nitrogen （ r = 0. 946 4） and patterns of soil moisture, contents of available phosphorous and available kalium in different riparian forests were different.
