Chinese name: Obstructive landscape mbth: Obstructive landscape, another name: landscape inhibition form: the role of rock barrier, shrub or forest barrier, etc. Increase the level of landscape architecture and other disciplines: the expression form, functional significance and application of horticulture, and the expression form of landscape obstruction is also called "landscape inhibition". All the barriers that inhibit the sight and guide the space are landscape obstacles, mainly to create a garden with a winding path and a deep courtyard. Obstacles can be divided into three types according to the arrangement position: entrance obstacle, end obstacle and bend obstacle. The entrance barrier scene is located at the entrance of Jingtong, which is set up to achieve the functions of promoting first and then restraining, increasing the level, organizing people flow and promoting ugliness. The terminal barrier is located at the end of the landscape sequence, and it is hoped that tourists will have endless aftertaste, which will play a role in lingering and memorable. Arc fence is the application of architectural theme. Usually, in a house garden, they often come to the garden through a turning corridor. They are called arc barriers. According to the materials used, it can be divided into shadow barrier, rockery barrier, mound barrier, shrub barrier, hedge barrier, group carving barrier, stone barrier and building barrier. The aesthetic significance of China people is based on the traditional cultural mentality and cultural edification, and has the characteristics of oriental culture and aesthetic consciousness. The traditional aesthetics of China people pay attention to implication, obscurity, emptiness, tranquility and profundity. I don't like to have a panoramic view when enjoying the beautiful scenery. I hope to add my own imagination to the aesthetic process, transcend the garden landscape, and understand the external image from the image, spirit and detachment. However, the obstacles in the garden landscape, like "hiding half her face in front of us behind her guitar" and "I want to stop talking", have aroused the curiosity and imagination of aestheticians and made them want to uncover the veil of the landscape. 1. Stimulating aesthetic interest In gardens, the landscape effect of "turning into a stream" is often used to stimulate tourists' aesthetic interest. When people go through a tortuous and closed journey, a "suddenly enlightened" landscape appears in front of them, which opens their eyes and is overjoyed. Their spirits are really high, and there is indeed some new joy. Especially in some large gardens, this method is often used: for example, the Summer Palace in Beijing, after entering from the East Palace gate, a neat and symmetrical palace, gallery and fence, just a little tired, bypassed Renshou Hall and came to Kunming Lake. 2. It can be said that the ugliness of the barrier is one of the functional manifestations of the barrier. First, some facilities in the same forest are unsightly or indecent and need to be covered with obstacles, such as garbage dumps and toilets in parks or scenic spots; Second, the boundaries of the garden (walls, fences) are covered by garden towels through the barrier landscape, which will make people feel "boundless wind and moon" and "infinite mountains and rivers" and increase the artistic conception of the garden. For example, Fuhai Scenic Area in the east of Wang Mingyuan, and Xiushanfang in the east takes Xishan Mountain as the scenery. Between the palace wall and the river, there is an earthen mountain, and the palace wall is properly covered up. This practice of "blocking the edge" can give people the illusion that there is a far sky beyond the green hills; Third, some places in the landscape park, such as office areas and employee activity areas, do not want tourists to enter or disturb, and set up barriers to separate these places from the scenic spots where tourists are active. 3. Improve the garden level and enrich the landscape. The creation of China's classical garden art pays attention to the beauty of hierarchy. A good garden will not let visitors see the essence of the whole garden at once, but, like music, there is a landscape sequence, which develops in turn from the beginning, development, * * * to the end. Taking rockery as a barrier, the Grand View Garden aims to avoid having a panoramic view of the whole garden as soon as it enters the park, but adopts the artistic techniques of first revealing and then hiding, first promoting and then restraining, so as to achieve the artistic conception of mountains, rivers, winding paths and secluded places. "A winding path leads to a secluded place" is a common technique in ancient gardening. Its intention is to create a quiet environment for people. The winding path leads to a secluded place, which can be seen everywhere in Jiangnan gardens. In some gardens, plaques with "secluded places" and "secluded paths" are clearly written at the entrance of scenic spots to arouse tourists' awareness. Apply 1. The screen wall is the barrier opposite or inside the gate of the ancient courtyard in China, also called the screen wall. Its building materials are brick, wood, stone and glass, and plant materials are gradually introduced into the barrier. Therefore, the screen wall should be wider. For example, in the East, West and Six Palaces of the Forbidden City, almost every group of palaces has a screen wall. The most exquisite screen wall is the three famous glazed Nine Dragon Walls in China. The screen wall built in Beijing quadrangle is to shield the messy buildings outside the gate, which makes people feel spacious and tidy when standing in front of the gate, and also shows the difference between inside and outside the quadrangle. 2. Rockery barriers and mound rocks, as landscaping elements, originate from people's worship of nature. After the rise of geomantic omen theory, stones, as barriers, constitute multiple enclosures and forbidden areas. Later, stone barriers became one of the landscaping techniques in the same forest. For example, the earth-rock barrier of Gongwangfu Garden in Beijing, the Huangshi rockery at the entrance of Humble Administrator's Garden, the Huangshi rockery in front of the entrance of Longhua Park in Shanghai, and the earth-rock mountain behind Yihe Copper Life House are all commonly used in classical gardens. 3. As barriers, the plant materials of shrub barriers and hedge barriers block people's sight, and their landscape effects are the most abundant: with different degrees of permeable plants, they can miss the scenery; The plant design with guardrails in the middle will form a frame view or a clip view. Therefore, when using plant materials as a barrier, it is necessary to analyze the position of the viewer, the height of the barrier, the distance between the viewer and the barrier and the terrain, which will affect the height, distribution and configuration of the plant barrier. In addition, there is a group sculpture at the entrance of the main entrance of Shanghai Martyrs Cemetery. The wall barrier includes the wall barrier of East Lake Park in Linhai. In fact, it can be used as a barrier material, and sometimes it can be used in combination of several materials and in various forms.
