Aiming at the problem of the recovery of degraded ecosystem construction, we set up a group of plant restoration model creatively on the basis of ecological restoration dynamics to analysis the relationship of the group of objects with environment, the implant group and the original species. Finally, by using the MATLAB software, we find that during artificial implant, we should choose herbal and shrub instead of arbor. Besides, we’d better choose a plant of similar species as implanted object to improve the ecological system.
