A combination vivarium assembly is formed by at least a vivarium, wherein the vivarium includes a bottom board, plural pillars, plural side boards, and a top board. Therein, the pillars have grooves thereon and are combined to the bottom board. The side boards are inserted in the grooves, respectively, and surround the bottom board to form a containing space. The top board is magnetically connected to the pillars. Through such configuration, the bottom board, the pillars, the side boards, and the top board are allowed to be assembled and disassembled easily. With magnets provided on the bottom board, the pillars, and the top board, other components can be added, while multiple vivariums can be stacked. Each board component can be substituted by a board having a hole, whereby multiple vivariums are allowed to be combined into a vivarium assembly, thus forming a larger eco-system.本發明提供一種組合式生態模組,由至少一生態箱所組成,該生態箱包括有:一底板、複數設有一柱體凹槽且接於該底板上的柱體、複數插入嵌接於兩相鄰柱體並圍設成一容置空間的側板、一磁接於各柱體上的頂板,藉由其中簡易的連接構造,使該生態箱之該底板、各柱體、各側板及該頂板均達到可輕易拆解組裝之便利,並於該底板、各柱體、該頂板上設置有磁鐵,使該生態箱得依照需求加裝其他部件及供複數該生態箱堆疊固定,另外該底板、各側板及該頂板均可替換成一設有洞口的底板、側板及頂板,進而將複數該生態箱接合成一生態模組。1‧‧‧生態模組10‧‧‧生態箱20‧‧‧底板30‧‧‧柱體32‧‧‧柱外磁鐵33‧‧‧柱體凹槽40‧‧‧側板41‧‧‧遮光片50‧‧‧頂板52‧‧‧頂板磁鐵
