| 摘 要： | 通过对侵蚀与非侵蚀黑土的渗透性能研究,结果表明,非侵蚀土壤的渗透速率大于侵蚀土壤,且达到稳渗的时间长于侵蚀土壤;侵蚀土壤与非侵蚀土壤的渗透速率呈现随土层深度的增加而减少的趋势;侵蚀土壤达到稳定的时间随土层深度的增加而延长,而非侵蚀土壤则随土层深度的增加而缩短。侵蚀与非侵蚀土壤的渗透速率均随着初始含水量的增加而下降;同一含水量下,非侵蚀土壤的渗透速率大于侵蚀土壤,且达到稳渗的时间长于侵蚀土壤;非侵蚀地与侵蚀地降雨前土壤的初渗速率和稳渗速率均大于降雨后土壤的初渗速率和稳渗速率,且降雨前后非侵蚀地渗透速率都大于侵蚀地的渗透速率;通过典型相关分析可知,土壤容重、总孔隙度和非毛管孔隙度是影响土壤渗透能力的主要指标。

| Abstract: | According to eroded and non-eroded soil infiltration properties were studied.The results showed that:non-eroded soil infiltration rate was higher than the eroded soil,and the steady time of non-eroded soil was longer than the eroded soil;non-eroded and eroded soil infiltration rate was decrease with increasing the soil depth;in the time of reach steady eroded soil was increased with increasing soil depth,but non-eroded soil was decreased with increasing soil depth.Non-eroded and eroded soil infiltration rat... |
