贵州西部四种典型林地土壤水文特性研究
Study on Hydrological Characteristics of Soils in Four Typical Types of Woodlands in Western of Guizhou Province
摘要
Abstract
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.关键词
