| 摘 要： | 于2005年4月,对不同地类、不同土层垂直深度、不同季节的土壤含水率进行了连续3a的定位测定,并探讨了影响土壤含水率的相关因子.结果表明,红松郁闭林分土壤含水率为22.52%,均超过未郁闭的红松纯林和红松-白桦混交林.表层(0～10cm)土壤含水率最高,为22.62%,并呈现出随土壤深度的加深而含水率逐渐减小.在水热同...

| Abstract: | Orientation determination of soil moisture content in Pinus koraiensis plantations was conducted on different types of land,at different vertical depth of soil layers and in different seasons for three consecutive years in April 2005.The related factors affecting soil moisture content were discussed.Results showed that the forests with closed-canopy had the highest soil moisture content(22.52%),which was higher than that of the pure P.koraiensis plantations with unclosed-canopy and the mixed forest of P.kor... |
