摘要
在气候逐渐变暖情况下,地处辽东山区的本溪县无霜期和冬季冻土深度也发生了明显变化。通过分析1958～2010年本溪县初终霜及冬半年冻土深度资料,结果表明:本溪县无霜期随气温升高呈延长变化趋势,而冻土深度则呈减小变化趋势,土壤解冻及化通时间均有所提前。
With the gradual warming of climate condition,frost-free period and winter frozen soil depth changed apparently in Benxi County which located in the Liaodong mountain areas.Through analyzing data of initial and final frost and frozen soil depth during half-winter during 1958-2010,the results showed that the frost-free period changes extensively with the temperature increase,while the frozen soil depth changes with the temperature decrease,soil thawing and through time are ahead of time.
