SPP 1315: Biogeochemical Interfaces in Soil

土壤是由固体、液体和气体组成的活泼、多相的三相系统。它是生物圈、水圈、大气层和岩石圈之间的动态界面，因此是“临界区”的基本隔间。优先方案范围内的研究旨在系统地确定土壤中生物地球化学界面的结构特征和功能，并揭示其对有机化学品命运和影响的作用。总体的联系科学目标是从机械上了解在生物地球化学界面上运行的物理、化学和生物过程的复杂的相互作用和相互依存关系。主要的挑战是确定控制生物地球化学界面复杂结构的因素，以机械的方式将在分子和生物尺度上起作用的过程与在聚集尺度上活跃的现象联系起来，并在一般机械框架内解释土壤中有机化学品的中长期行为。这项研究基于以下假设：

Soil is an enlivened, heterogeneous three-phase system made of solid, liquid and gaseous components. It serves as a dynamic interface between the biosphere, hydrosphere, atmosphere and lithosphere and is thus the essential compartment of the "critical zone". Research within the Priority Programme aims at the systematic structural characterisation and functional exploration of biogeochemical interfaces in soil and at unravelling their role for fate and effect of organic chemicals. The overall connecting scientific goal is to gain a mechanistic understanding of the complex interplay and interdependencies of physical, chemical and biological processes operative at biogeochemical interfaces. Grand challenges are to identify the factors controlling the complex architecture of biogeochemical interfaces, to link the processes operative at the molecular and organism scale to phenomena active at the aggregate scale in a mechanistic way and to explain the medium- to long-term behaviour of organic chemicals in soil within a general mechanistic framework. The research is based on the following hypotheses:
