| 摘 要： | 基于冬季野外大田土壤入渗试验,以北方高寒地区——哈尔滨为例,分析了冻深对冻结土壤入渗能力的影响。结果表明,冻结土壤入渗能力与非冻结土壤相比具有较大的区别,其入渗能力要远小于非冻结土壤,冻结土壤具有明显的减渗特性。研究结果对于指导北方高寒地区科学合理地制定冬春灌溉技术指标及高效利用土壤水资源具有重要的理论和实践意义。

| Abstract: | Based on soil field infiltration test in winter,taking northern extremely cold area——Harbin as example,the effect of frozen depth on infiltration capacity was analyzed.The results showed that frozen soil infiltration capacity was very different from that of unfrozen soil.The infiltration capacity of frozen soil was less than that of unfrozen soil and frozen soil had obvious reduction infiltration characteristic.The research results have practical and theoretical values for guiding to irrigate reasonably in winter and spring,and effectively utilize soil water resources in northern extremely cold area. |
