《白土案》述及南康府星子县因开挖白土而引起的环境变迁。开挖白土仅仅是陶冶的一个步骤,就引起了人与环境关系的恶化,正是这种恶化酿成此案的发生,造成了对当地环境的三大威胁:危及田园,危及庐墓,危及地脉风水。南康府最终决定封山禁开,以保护环境。本文基于文献资料上分析了此案所涉及的陶冶对小环境的这三个威胁。 The “Case of Clay” refers to the environmental changes caused by excavation of clay in Xingzi County, Nankang Prefecture. Excavation of clay is only a step in the process of cultivation, causing a deterioration in the relationship between man and the environment. It is precisely this deterioration that has led to the occurrence of the case, resulting in three major threats to the local environment: endangering the garden, endangering the Lu Tomb and endangering Geomance feng shui. Nankang government eventually decided to close the mountain closed to protect the environment. Based on the literature, this article analyzes the three threats to the small environment that are involved in this case.
