Landscape as the object of visual aesthetics, the habitat of life. It reconciles people and the external environment, and to some extent both benefit. It also shows the harmonious development of human and environment.

Human beings depend on land for their survival and must also protect the environment. Human beings have all kinds of material and spiritual needs, which promote the continuous development and progress of science and technology. Outdoor landscape is the art of designing, planning and managing land. The emergence of new materials for outdoor landscape comes from the emergence of new technology. People began to use natural materials to produce bricks, tiles this artificial material so that for the first time humans broke through the natural materials of the bondage. Bricks and tiles have been important materials for more than two thousand years. Metal material applications use iron history beginning in the 1670 s, the early nineteenth century began to use wrought iron, in the 19th century produced tensile, compressive strength, good ductility, building steel of uniform quality. Concrete was also invented in the 1820s. The materials used in modern times include various alloy materials, glass fibre reinforced plastic materials, nanomaterials, wood plastic composite materials, etc. We can see that the time for the material to emerge and change is getting shorter and shorter.

In today’s huge energy consumption, if we don’t pay attention to environmental awareness, the environment we live in will become terrible. The loss of soil, wood, metal, water, energy, whatever materials are used in the landscape, is a disaster for humans. Therefore, we are actively developing environment-friendly and energy-saving materials. An indirect measure to reduce the consumption of wood is the production of antiseptic wood. Wood is a kind of biological organism. When used in the outdoor environment, it is easy to be eroded by microorganism and termite, thus losing its commercial value. Anticorrosive wood is a special that the systematic pressure impregnating anticorrosive processing, have anticorrosive, antibacterial, prevent termites effect, beautiful and durable, its normal service life in thirty years to fifty years or more. At present, antiseptic wood is widely used in the market. There are municipal landscape, viewing platform, anti-corrosion wooden bridge, anti-corrosion wooden ladder, amusement facilities, anti-corrosion wooden road, tables and chairs, garden pavilion, anti-corrosion wooden furniture, landscape villas and so on. Its landscape effect is good, deeply loved by the masses.

In order to protect forest resources and reduce the use of new timber, the recycling of low-cost used timber and plastics has become a common concern in industry and science. Thus, wood plastic composite materials, the wood plastic composite material is wood fibre and plant fibre as the main ingredient, after pretreatment with thermoplastic resin or other material combination and become a new type of material. Its performance is: the good mechanical strength, high impact strength, heat sealability and absorbent are smaller than wood, good size stability, abrasion resistance, resistance to chemical corrosion, not afraid to eat by moth, nonflammable, it possesses the processability of the wood and plastic. Saw, planing, spinning, cutting, cutting, tapping, pasting and glueing can also be extruded, pressed, injection moulding. The characteristics of this material determine the great development space of wood-plastic composite materials. Such environmental protection, energy – saving building materials are now being widely used in the market and people’s life.
