摘要
对贵州省西部地区桦木林、柳杉林、华山松林和杉木林4种典型林地土壤的物理性质和水文特性进行了初步研究。结果表明:4种林地土壤容重、毛管孔隙度、贮水深和毛管持水深均随土壤深度的增加而增大,总孔隙度、非毛管孔隙度、最大持水深和渗透性具有随土壤深度的增加而减小的趋势。综合评价4种典型林地土壤物理性质和水文特性,桦木林地土壤平均非毛管孔隙(16.29%)和渗透性(2.77mm/min)最大,表现出较强的蓄水能力;华山松林地土壤平均总孔隙度(66.70%)最大,表现出较大的持水深。
A pilot study on hydrological characteristics and physical properties are studied in four typical types of woodlands,which Betula luminifera H.Wink forest,Cryptomehia fortunei forest,Cryptomeria fortunei forest and Pinus armandi forest are grown respectively in western region,Guizhou Province.The results showed that： soil bulk density,capillary porosity,water storage and capillary capacity of the four typical types soils in woodlands increased with soil depth;the total porosity,the capillary porosity and permeability,maximum capacity decreased with soil depth.In terms of comprehensive evaluation on physical properties and hydrological characteristics of soils in the four typical types woodlands,the average capillary porosity（16.29%） and permeability（2.77 mm/min） of Betula luminifera H.Wilk is the maximum,showing greater storage capacity;the average total porosity（66.70%） Pinus armandii Franch is the maximum,showing greater water holding depth.
