Spatio-temporal patterns of Q(10) values for improved modelling of heterotrophic soil respiration (B03)

群落土地模型(CLM)作为TerrSysMP的一部分，假定异养土壤呼吸对温度的依赖是固定的。然而，我们的发现表明，土壤的质地、孔隙度、湿度和营养状况对温度的依赖是可变的。我们计划衡量这些因素对土地利用和土壤单位的影响。我们将使用近距离和远距离土壤遥感，以实验室中红外光谱和我们的RESPICOND系统土壤培养为支持，测试鲁尔流域选定部分的已发现的关系。潜在的改进将在CLM中实施。

The Community Land Model (CLM) as part of TerrSysMP assumes a fixed temperature dependency of heterotrophic soil respiration. Our findings indicate, however, a variable temperature dependency as a function of texture, porosity, moisture, and nutrient status of the soil. We plan to scale the influence of these factors in relation to land-use and soil unit. We will test the found relations for selected parts of the Rur catchment using proximal and remote soil sensing, backed up by lab-based mid-infrared spectroscopy and soil incubations with our RESPICOND system. Potential improvements will be implemented in CLM.
