The key to success or failure of rockery in courtyard landscape lies in rockery design, and the design of mountain facade is the key to rockery design. The facade modeling of rockery engineering must be based on the principle of static balance. Even for the artistic beauty of rockery, there is a sense of instability in its modeling, but in the structural mechanics, it is still necessary to achieve the static balance relationship according to the balance distribution method, so as to achieve the internal balance in the appearance similar to instability. The facade design of rockery production should pay attention to the three problems of body, surface, line and pattern.
Generally, for the whole elevation near the mountain, the method of convex, concave and straight down is often adopted to deal with its surface structure; and if it is a large-scale rockery project, the foot of the vein slope is often used to reflect its "far mountain to examine its potential, near mountain to see its quality". A rockery in the spatial facade of the flat, curved, concave, convex, virtual, real and other ornamental texture. The facade design of rockery in rockery engineering should avoid the straightness of copper wall and iron wall, but should use the size, texture, concave and convex of stones and holes to show the contrast between light and shade. At the same time, the rockwork material should be made of large blocks, supplemented by small blocks. There should be a distance between the stones, so that the shadow can be formed under the light, or it is conducive to the growth of plants. Otherwise, full expansion of mortar will result in no grass and no interest.
The synthesis of the contour line of the whole rockery design or the contour line of the local level. Finally, it can be composed like the rhythm and melody of music, from low to strong, fluctuating and changeable, until the climax.
In the design of rockery, the proportion between the sight distance and the volume of rockery (the scenery to be viewed) should be fully considered. For the specific facade design, first of all, the rockery should be tall, gentle, towering or precipitous, with reasonable layout and artistic treatment for its mountaintops, mountainsides, mountain corners, etc., which can be fully expressed by drawing on the traditional Chinese landscape painting. For the combination of multiple body shapes in facade design, especially the combination of mountains, we may also use the combination method of spatial triangles for reference.
Therefore, the design of garden landscape rockery needs to lay out several combination units of rockery in a certain space, which is suitable for construction. The arrangement of the rockery plane in the rockery project should also be consistent with the specific situation of the actual site of the rockery project, so as to make the rockery really play a role of foil in the courtyard landscape.
