图7 冻土特征参量的空间趋势率特征及显著性水平
注:左半部分为空间倾向率计算结果,右半部分为相应参量倾向率的显著性水平空间分布;折线图分别展示了呈现显著上升(P1)、显著下降(P2)和不显著上升(P3)等变化趋势。
Fig. 7 Spatial trend rate characteristics and significance level of characteristic parameters of frozen soil: profile temperature (a), liquid water content (b), ice content (c), and surface heat flux (d)
Note:The left half is spatial distribution of tendency rate of various parameters,and the right half is spatial distribution of significance level of the corresponding tendency rate;the line chart shows trends of significant increase(P1),significant decrease(P2),and insignificant increase(P3).
