In the construction of gardens, the fabrication of rockeries began in the Qin and Han Dynasties, and began with mounds of earth. Although the momentum of the mountains had changed, there was no precipitous interest in stones, so it developed to use real stones to build rockeries. In the Wei, Jin, Southern and Southern Dynasties, landscape poetry and landscape painting began to flourish, which had a great impact on garden construction. Despite imitating natural rocks and rocks, the combination of rockery and gardens has the charm of Chinese landscape paintings, and the interest of gardeners in expressing their feelings for mountains and waters can be gathered in specific scenes. The history of making rockeries in gardens has been nearly two thousand years.
The development of rockery production should go through four parts: material selection, pond building, Hill folding and decoration. Material selection: The production of large-scale rocks, whether hard or soft, whether absorbent or non-absorbent, requires the unification of stone materials and specifications (block or strip). Pool building: stacking mountains and managing water, pool building is a means of managing water. Water is the blood of mountains, while water is the soul. There are many types of pools. It is usually round, usually 5 to 10 meters in diameter and 80 to 120 centimeters in depth; the water depth is subtracted from 20 centimeters along the mouth and maintained from 60 centimeters to 100 centimeters; there are pipes at the bottom of the pool to discharge water. Mountains overlapping: Artificial hills are either multi-body (combination type) or single-body (solitary peak type); they are composed of three parts: main peak, object peak and lining (low mountain).
During the Wei, Jin, Southern and Southern Dynasties, the flourishing of landscape poetry and landscape painting had a great impact on gardening. It was shown in the way of setting the scenery of rockery in the production of rockery, which generally adopted the lofty and far-reaching methods in traditional Chinese painting.
(1) The subject should be on the left or right side of the front. If the subject is on the left, the object is on the right, forming an open-close type, a big one, a small one, a tall one, a short one, and echoing with each other.
The main peak is tall and steep, and the back hillside extends slowly, which is connected with the backseat liner (remote mountain). In front of the main peak, it forms a way to hide first, which makes people feel that the greater the realm is, the more attractive the central landscape is to "see but not see clearly", which makes visitors have to move forward to see what is going on.
(2) The height ratio of the main body is the same as that of the high-distance method. Its position should be arranged on the left or right side of the middle, and the object should be placed on the right or left side of the front. The subject and object have a wrong front, a wrong back, echo each other remotely, and the lining is behind. The multi-layer structure of a single scene forms all levels of the near (object) medium (subject) and far (lining) scenery, thus enhancing the positive perspective and increasing the depth of the landscape. Generally, the total area of mountain body does not exceed half or less of the water surface. In this way, leave enough blank space for the viewer to associate and imagine, to achieve the effect of "scenic scenery here" and "visible reality in the empty". "Mountains are clothed with trees, and trees are built with mountains as bones." Only by reasonably allocating plants, can mountains and rivers have bones, flesh and spirit.
The rockery is made of plants with beautiful posture, small evergreen leaves, low growth, long life and strong adaptability.
