摘要: 为了研究文峪河上游3种典型河岸林土壤理化性质之间的差异,对河岸林土壤的pH、容重、总孔隙度、毛管孔隙度和毛管持水量进行了测定分析。结果表明:土壤理化性质在不同类型河岸林之间的差异达到极显著水平;3种典型河岸林土壤pH和容重表现为:华北落叶松河岸林>杨桦河岸林>云杉河岸林,总孔隙度、毛管孔隙度和毛管持水量表现为:云杉河岸林>杨桦河岸林>华北落叶松河岸林;3种典型河岸林土壤pH随土壤深度增加而增大,距离河流越近总孔隙度越小,其他方面无显著规律。

Abstract: In order to study the differences of the soil physical and chemical properties among three kinds of typical riparian forests of Wenyu River upstream, some parameters, such as soil pH, bulk density, total porosity, capillary porosity and capillary water capacity, were measured and analyzed. The results showed that the differences of the soil physical and chemical properties were very significant among different types of riparian forest; the soil pH and bulk densities of three kinds of riparian forestry had an order as: larch riparian forest>birch riparian forest>spruce riparian forest; the soil total porosity, capillary porosity and capillary water capacity had an order as: spruce riparian forest>birch riparian forest>larch riparian forest; the soil pH of three kinds of riparian forest increased with the soil depth, and soil total porosity decreased with the distance getting close to the river, no other apparent regularity was detected on soil properties.
