摘要: 对辽宁省北票县刺槐-油松混交林、刺槐、油松纯林及无林地土壤水分的物理性质和持水特性进行了测定。结果表明:刺槐-油松混交林的土壤孔隙状况、机械组成、持水性能、渗透性能和储水量均明显优于无林地和2种纯林。刺槐和油松纯林的各项指标均明显优于无林地,刺槐和油松纯林的各项指标处于相近水平。综合评价表明:在持水能力方面,以上3种林型中,刺槐-油松混交林是该地区最优的林分类型。同时建立了混交林土壤饱和导水率主要影响因子的线性回归方程。

Abstract: In this study, the physical properties of soil moisture and soil water retention were measured in plots of 20 m×30 m in the mingled forest of Pinus tabulaeformis Carr. and Robinia pseudoacacia L., pure forests of P. tabulaeformis Carr. and R. pseudoacacia L., and nonforest land in Beipiao County of Liaoning Province. The results showed that the soil physical properties including soil porosity, soil mechanical composition, soil water retention, soil permeability and soil water storage capacity in the mingled forest of P. tabulaeformis Carr. and R. pseudoacacia L. were all better than those in the pure forests and nonforest land. All the values of soil in the pure forests of  P. tabulaeformis Carr. and R. pseudoacacia  L. were similar. The comprehensive evaluation revealed that soil water retention in the mingled forest of  P. tabulaeformis Carr. and R. pseudoacacia L. was the highest among the three forest types. The linear regression equations of the main factors affecting the saturated hydraulic conductivity (EMAS) were developed.

Key words: mingled forest of Pinus tabulaeformis Carr. and Robinia pseudoacacia L., soil water retention, soil permeability, soil water storage capacity, Liaoning Province
