Garden hard materials play an important role in the construction of conservation-oriented gardens. The selection and design of hard materials are related to the overall appearance of the garden, which is an important part of building an economical and sustainable garden. After expounding and summarizing the design principles of garden hard materials in conservation-oriented gardens, the important role of garden hard materials in building conservation-oriented gardens is summarized, including reflecting local cultural characteristics, reusing with conservation-oriented design concepts, and promoting the research and development of new environmental protection materials. Therefore, it reflects the significance of garden hard materials to sustainable development.

Key words: garden hardwood (thanks: publishing papers, writing graduation papers, publishing papers, publishing medical papers, publishing paper titles, paper titles); Building economical gardens; Sustainable development.

Economical landscaping is to maximize the comprehensive benefits of landscaping with the least resources and capital investment, and promote the sustainable development of urban landscaping construction. Garden materials are divided into two categories: plant materials and corresponding hard materials. Hard materials include all kinds of stone, wood, concrete, metal and glass used in landscape engineering. These hard materials play an important and irreplaceable role in the construction of garden masterpieces and are an important part of all aspects of garden architecture. Therefore, the scientific and rational application of hard materials in gardens is of great significance to the construction of conservation-oriented gardens.

First, the design principles of garden hard materials in the construction of conservation-oriented gardens

(A) pay attention to ecological benefits

Building a conservation-oriented garden means building an ecological garden. The theme should be reflected in environmental protection. Promote the use of environmental protection materials on garden hard materials to balance the internal ecosystem of the garden. The components of the system are coordinated and matched with each other in structure, quantity and function design, and a beautiful picture is constructed with the same structure. Designers should pay attention to the choice of materials when building gardens, and don't use natural wood and stone resources to avoid the damage of over-exploitation to nature, resulting in soil erosion and vegetation destruction. Moreover, we should pay attention to the recycling of natural resources and the development of new technologies, methods and means, and create more and better landscapes for tourists to enjoy without destroying too many resources.

(B) the inheritance of regional culture

Local garden landscape is an important building reflecting local culture and local cultural style. The differences between the north and the south and between the east and the west are different, so the garden styles and cultures represented by different regions should also be different, and the gardens also have distinct differences in hard materials. For example, the landscape in the south is mostly made of lake stones and bamboo, which is quiet and elegant and beautiful; The hard materials in the north are mostly rocks and bricks, which are slightly majestic. In garden construction, the use of materials that can represent local cultural characteristics and local customs can not only make the garden meet the life and entertainment needs of local people, but also greatly promote local cultural and social benefits, which is conducive to local development.

(3) Improve economic benefits

In garden construction, we should pay attention to the principle of circular economy, rationally use hard materials and reduce waste. We should know how to use advanced technology and measures to make rational use of waste and obsolete man-made materials and turn them into useful materials. For example, the metal frame and concrete materials, various types of clay bricks, glazed tiles and various synthetic materials replaced in the process of landscape transformation can be transformed through different processes and applied to landscape construction to reduce construction costs.

(D) Follow the design concept

In the process of selecting hard materials, we should comprehensively consider the selection of materials, not only considering economy and economy, but also selecting matching materials from the aspects of texture, service life and long-term and short-term comprehensive benefits of hard materials. Materials that show modern style, such as steel plate and glass, are rich in artificial flavor, rich in modeling, exquisite and delicate, and are commonly used elements to shape modern garden style.

Second, the important role of garden hard materials in the construction of conservation-oriented gardens

Based on the analysis of design principles and concepts, the concrete application and design techniques of hard materials in gardens are summarized in order to build an economical garden. Conservation-oriented gardens should consider sustainable development, minimize the input of circular economy, resources and energy, maximize social, cultural and economic benefits, help build a green model of harmonious coexistence between man and nature, rationally use local materials, waste materials and eco-friendly materials, and reduce the adverse impact of various materials on the environment.

(A) clever use of local materials, highlighting local culture.

Clever use of local hard materials to reflect local culture will facilitate foreign tourists to learn more about local customs and beautiful landscapes, stimulate local cultural, social and economic benefits, and promote ecological balance.

1, processing local materials with modern technology

In landscape design, the application of traditional local materials can reflect the regional characteristics that the works continue rather than break, and are familiar rather than unfamiliar. After hundreds of years of baptism, local materials have their own unique expression techniques. Based on the unique understanding of garden art and material characteristics, landscape designers can fully tap the new technologies applied by traditional materials. In modern gardens, ceramic tiles, as one of the traditional building materials in China, have been endowed with richer functions, which can not only be used to pave sites and roads to form a unique curved texture, but also be used as bricks to build landscape walls, windows and other garden sketches.

2. Combination of local materials and new materials.

The appearance of new materials has brought a new atmosphere to the garden, making the garden works full of modern art, but it is slightly insufficient in reflecting local culture. The combination of local materials and new materials can complement each other and coordinate with each other, which not only meets the requirements of modern aesthetics, but also continues the regional culture.

(b) Developing design concepts and recycling waste materials.

1, new use of waste

For those demolished waste materials or useless materials, as long as landscape designers can skillfully use them, they can develop their bright spots in the garden. This can not only save the engineering cost, but also effectively use the waste and reduce the generation of garbage. In modern garden design, all kinds of stone materials with ecological labels are widely used in places such as ground paving and wall veneer, and even the thickness and polishing degree of stone materials have become one of the standards for evaluating garden quality.

2. Recycling of waste materials

Wood is a common material in landscape design, but it is easy to corrode, crack and deform, and its service life is short, so it needs to be replaced regularly. The replaced wood should continue to be recycled to maximize its ecological benefits. For example, large materials such as removed wooden beams and columns can be processed and transformed into small-sized wooden frames if the quality is good; If the corrosion is serious, it can be transformed into a flower pond or crushed into small pieces of wood to make a ground cover. This can not only cover the bare planting soil, keep the soil moisture, but also meet the environmental protection requirements of absorbing rainwater.

(3) Actively research and develop new environmental protection materials.

In the process of using common hard materials in garden construction, some management problems will inevitably appear, which will remain unchanged because of high price or frequent maintenance. The use of wood products will cause expensive anticorrosive wood to crack and paint to fall off in the face of constant wind and rain, and rainwater and wood materials are prone to chemical reactions, resulting in decay. Therefore, based on various inconveniences and disadvantages, designers should constantly develop new hard materials and new resources for production and construction through scientific and technological means to meet the quality development of garden construction. In recent years, some materials with good eco-environmental performance have appeared, such as wood-plastic products. Take wood fibers and thermoplastics as examples. These products are sawable, planed, tenoned, moth-free, and easy to construct and maintain. During use, they will not emit volatile substances harmful to human health, and the products themselves can be recycled without reducing their physical properties.

Today, conservation-oriented society has become one of the main construction directions of the government, and conservation-oriented gardens are also one of the key points to reflect the construction of contemporary landscape environment. The selection and selection of garden hard materials needed for garden construction has become an important work that cannot be ignored. In the planning, design, construction and maintenance management of urban garden ecological greening, it is necessary to protect the garden hard materials at all stages and check and repair them regularly, which can not be ignored for the safety and aesthetics of garden landscape. This paper summarizes the importance of garden hard materials in building conservation-oriented gardens, including clever use of local materials, highlighting local culture and expanding design ideas. The recycling of waste materials and the active research and development of new environmental protection materials show that garden hard materials optimize the ecological, social and economic benefits of urban gardens and lay a good foundation for building a harmonious society.

Sorry, it's exactly the same. No, I personally think that hard building materials and new building materials are also a kind of garden building materials. The function of garden building materials can be written from these two aspects.
