| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 105 === Shellfish culturing not only produces food but also could provide benefits like carbon sequestration, water purification, reduction of agricultural waste, and harboring wildlife. Due to climate change and disease it has become harder and harder to achieve successful operations. Soil plays an important role in the eco-system by buffering water quality, storing nutrients, and prevention of disease. Fractal analysis on pore geometry can assist the determination of soil health. Fractal is a mathematical tool for characterizing complicate geometric patterns. By using box counting method on 2D images of pores, self-similarity of patterns at different scales can be enumerated as fractal dimension. The aim of this work is to understand the mechanics that organize soil particles. Soil without or losing microbial activity normally has fractal-like pores with high fractal dimensions. Soil with high microbial activity normally appears non-fractal.
