Abstract: With the improvement of people’s living standards, people’s pursuit of material and high quality of living environment must combine the concept of human and nature to integrate urban landscape design with the surrounding ecological environment. The most interesting thing is the landscape design of most coastal cities. Based on this, a virtual environment is proposed based on virtual reality technology and intelligent algorithm, using 3-bit binary to represent the digital factor and creating the virtual environment by simulating the display environment. After constructing the basic model of coastal landscape, the landscape design of coastal areas using virtual reality technology is analyzed, and the parametric design method of new images in landscape design analyzed, the landscape design of virtual reality technology in coastal areas analyzed. The research results show that the display degree of DEM is 50% and the image display detail degree is 90% by using virtual reality technology. Combined with 3DMAX, it can be transferred to the 3DMAX operation surface to perform real editing and simulation of the coastal garden environment. Thus, the algorithm proposed in this paper is effective. The research in this paper shows that it is feasible to apply virtual reality technology and intelligent algorithm to landscape design in coastal areas, and has achieved certain effects.
