The present invention relates to: a tunnel-type greenhouse dome having a space frame structure, which can obtain a maximum nurturing area over a minimum amount of area and can control optimum environmental conditions necessary for the growth of animals and plants inside the greenhouse dome through computer control using various sensors and an ultra-intensive multilayer structure using a maximum area by forming multiple layers inside the greenhouse dome.To this end, the present invention comprises: mesh vinyl provided outside and inside a sealed space frame for forming a greenhouse dome, and having meshes which are inserted and bonded to vinyl and a sunlight-sensitive discolored film, so as to allow the greenhouse dome to be sunny and the inside of the greenhouse dome to be protected from typhoons, deep snowfalls, and hail the sealed space frame for preventing freezing and bursting and corrosion inside a pipe among space frame structures, wherein the space frames form anchor spots in a plurality of columns and beams of a multilayer structure such that pipe members for forming a space frame structure are as thin as possible so as to enable sunlight to be maximally projected to the inside of the greenhouse dome a sterilizing and disinfecting facility provided at the entrance of the greenhouse dome a dust collection filter and an antibacterial filter provided in a blower fan for forcibly introducing outside air, in the lower part of the greenhouse dome and a dust collection filter and a plasma device provided in a blower fan for forcibly discharging inside air, in the upper part of the greenhouse dome, so that dust and bacteria generated from the inside of the greenhouse dome can be removed and gas is decomposed so as to discharge clean air to the outside. Meanwhile, the present invention enables: a sliding film to be provided in an inlet and outlet vent as a means for maintaining a normal atmospheric environment when the atmospheric environment inside the greenhouse do
