Cho et al. proposed the use of interactive genetic algorithm to express the cycle iteration relationship of design activities in view of the complex iterative cycle in garden engineering design, so as to clearly reflect the data mutual extraction between design activities [8]. Eikelboom et al. proposed a DSM- GA algorithm compiled based on the critical path Method (CPM), and applied the genetic algorithm to the design activity matrix to find a better order arrangement of design activities, so as to optimize the design iteration and shorten the design period [9]. Venema and Calamai extracted the geometric feature analysis model of garden landscape spatial environment design image, and realized garden landscape spatial environment design and image visual reconstruction through the 3d reconstruction method of computer vision features [10]. Banyai used pixel tracking and fusion technology to construct key feature quantity of landscape spatial environment design image, and realized landscape spatial environment design and optimization recognition [11]. 1.2 Contribution On the basis of the current research, this paper proposes an optimization design method of landscape space environment based on interactive genetic algorithm.
