图1. 试验期间各处理下5 cm土层土壤日平均温度、70 cm空气日平均温度和5 cm土层土壤含水量(平均值±标准偏差)的季节动态。P0W0、P0W1、P1W0、P1W1分别指不同处理方式: 去除植物+不增温、去除植物+增温、不去除植物+不增温、不去除植物+增温。
Fig. 1. Seasonal transitions of daily mean soil temperature at 5 cm below the soil surface, daily mean air temperature at 70 cm high and soil volumetric moisture at 5 cm below the soil surface under different treatments (mean ± SD) during the experiment period. P0W0, P0W1, P1W0, P1W1 are refer to the different treatments, indicated removal-plant + controlled temperature, removal-plant + increased temperature, unremoval-plant + controlled temperature, unremoval-plant + increased temperature, respectively.
