But because of the aggression of eight-power allied forces, the most scenery of it had been destroyed. This article took the example of ancient landscape architecture reconstruction of old summer palace, and explained the whole process to reconstruct landscapes with virtual reality technique which mainly includes the data acquisition and processing, visualization of 3D landscape and decoration of virtual reality technique professional software. In addition, this text studied the quality evaluation criterion of reconstruction of ancient landscape. With the example of Shang Gan village, to evaluate it with model number, number of textures and average FPS three aspects. So the evaluation criterion is to ensure the weights of the three aspects.
