For assessing the impact of soil temperature on tree growth in remote areas such as the alpine timberline, we introduce a new method for soil temperature manipulations. This new approach is based on roofing of the rooting zone and allows either soil cooling or soil warming without significantly influencing soil water availability and the above ground microclimate.

意见书：模拟土壤温度对高山林线松柏茎直径增量的影响：一种基于根区屋顶的新方法

为了评估土壤温度对高山林线等偏远地区树木生长的影响，我们引入了一种新的土壤温度操作方法。这种新方法基于生根区的屋顶，允许土壤冷却或土壤变暖，而不会显着影响土壤水分可用性和地上小气候。
