長期以來，人們將微生物與病原體畫作等號，但實際上有許多微生物定居於體表、腸道等位置與人體細胞協力維持身體的運作。現今人體的微生物群系是人類長期與環境互動、適應與共同演化的結果，而微生物多樣性最為豐富的土壤則是協助建構健康人體菌叢的要角。現代都市化的生活減少了人們親近土壤的機會，人體微生物菌群多樣性的降低與這樣的生活改變息息相關。在這樣的背景下，本論文以佔領為概念、微生物菌落為主題進行創作，回應此種人類對於大自然看似疏遠、宰制，實則無法分割的處境。在爬梳了與微生物菌落相關作品、並分析了作者所創作之《佔領》系列的前兩件作品後，作者製作了一款以在瓊酯培養基上培菌為靈感的擴增實境體驗：觀眾的知覺由土壤培養出來的菌落製成的標本物件透過應用程式延伸至土地本身，而觀眾在虛擬培養基上劃菌的同時也在觸摸土壤的同時被土壤微生物所佔據。作者試圖藉此體驗引發觀眾對於人類以及其所身處環境之間關係的思考。

People have been equating microbes as pathogens for a long time, while many of them settle on our body surface, inside our intestine, and other places cooperate with human cells to maintain our body function. Adaptation, coevolution and long-term interactions between humans and microbes in the living environment shape the human microbiome. Soil, rich in microbial diversity, is crucial to construct a healthy human flora. However, living in a modern, urbanization life reduces the opportunities to contact the soil, and the diversity loss of human microbial flora is closely related to such changes in life. This thesis aims to respond to this situation, where humans seem to alienate and dominate nature yet are inseparable from nature by artwork creation using "occupation" as the concept and the microbial colony as the theme. After combing through works related to microbial colonies and analyzing the context of the author's first two artworks in the "Occupation" series, the author created an augmented reality experience in-spired by the dish culturing techniques. During the process, audiences' sense ex-tends from the epoxy specimen made by the colonies cultivated from the soil to the land itself through the mobile application; when the audiences streak the virtual microbes on the ground, as virtual culture medium, with their bare hands, the audiences themselves are occupied by soil microorganisms at the same time. The author attempts to trigger the audience's thinking about the relationship be-tween human beings and the natural environment by this creation.
