I. Current situation of the industry

Landscape architecture in the modern sense has developed from the 1950s of 19 to today, and has a wider meaning and requirements. It is a synthesis of art and science, involving architecture, plants, ecology, art, tourism, environmental protection, geology, landforms, social and economic development, etc., which requires designers to master and have comprehensive qualities in all aspects. Landscape design is a very serious professional work, and an unprofessional, irregular and unreasonable design scheme will cause great damage to the ecological environment.

At present, China's landscape design market is not standardized, which leads to the phenomenon that designers and design units are mixed. First of all, many non-professional, inexperienced and low-quality designers are flooding the design team. Secondly, China implements the qualification grading system for design units, and has strict regulations on the professional personnel allocation, site, hardware and equipment requirements, and work scope of different qualification units. However, under the market economy system, all kinds of professionals are highly mobile, and their qualifications or qualifications cannot accurately reflect the working ability of design units.

This irregularity leads to unbalanced competition in the design market. Design companies often get design business by reducing design rates. The original design rate has taken the lower limit of the national rate. This abnormal competition makes the design company worse and overwhelmed. In addition, the owner often requires to complete the design task in a short time, which makes the design unit and designer unable to devote their energy to the full demonstration in the early stage of the design project and the guidance on the construction site in the later stage, which eventually leads to the slow progress of the project and even the destruction of the natural environment.

The direct victims of unbalanced competition are medium-sized design units, especially unqualified emerging design units. Because large-scale design units are state-owned units established before the reform and opening up, with high qualifications, they have more advantages when owners often pursue high-quality and overseas designers. But after all, these units are a few, and the number can not meet the requirements of China's expanding landscape design market and design theory innovation.

Due to the imperfection of landscape design norms and systems, when there are differences between the design unit and the owner unit, it is often difficult for the design unit to adhere to its correct opinions and sometimes even become a cartographer of the owner unit for the sake of the unit's survival and timely recovery of design funds according to the contract. At the same time, because the design unit can't effectively express opinions on the use of garden products such as building materials, garden sketches, lamps and seedlings, and the acceptance of project completion, many products that do not meet the design requirements often enter the construction, which affects the final effect of design.

Today, landscape design has a great impact on the natural environment, urban environment and ecosystem, so it is an urgent problem to standardize the landscape design industry. Standardizing the landscape design industry mainly includes four aspects: the cultivation of landscape designers, professional certification, management and the improvement of design laws and regulations.
