Guide, guide, guide and guide, are considered to be the same or similar content in many professional books. According to its meaning can be understood as instruction, guidance and sight. The guidance system refers to a complete information indicating system in a region, and there are many types of guidance, which are generally summarized as four types:

1. Indicative guide card. Provide route guidance for people to know the route of unfamiliar environment at a glance. The design focuses on the direction of the regional direction information and the provision of public service facilities and other information.

2. It is used to reveal the rules and regulations of public space and regulate the signs of people's behavior. Through this kind of sign, can promote conservation of nature, close to the environment information, remind people to pay attention to its own responsibility, make the person's behavior conforms to the principle of a healthy life, avoid and prevent the happening of the accident.

3. Introduction signs. It is used to explain the situation in the region, which can help people understand the environment and enrich people's vision. 4. Caring sign. Purpose is to promote environmental protection, ecological tourism, the national fitness slogans such as, advocate to build a harmonious coexistence between man and nature, fully embody the humanistic care, make up the lack of other signs content at the same time. With the increasing of environmental types, the cross and influence between environment and environment are becoming more and more obvious, and the types of modern guide are also being enriched, and the detailed rules of division are still to be perfected.

I. The development of public guide design in our country.

Compared with foreign countries, although the guide design of our country started late, it developed very quickly. In 1938, the national standard gb3818-1983 was promulgated for the first time, and 15 graphic symbols used in public places were stipulated in the standard. The development and implementation of these standard symbols have created a precedent for standardization of public information graphic symbols in China. After 2000, the state bureau of quality and technical supervision has issued a GB/T10001 "logo with public information graphic symbol" series standard, the standard symbol for the species divided more, the message content is more accurate and vivid, the rapid development of urban space, would send charcoal in the fire. In some eastern developed cities, the development of guided vision is quite mature. Such regions, such as guangzhou, shenzhen and Shanghai, represent the development frontier of the design of China's guide system. Many fully functional and unique guided vision systems play an important role in the convenience of people's life. Good material foundation and technical support provide an unprecedented opportunity for the development of visual design. The wide application of new materials and new technologies greatly improves the function of the guide.

Of course, there are many problems. First of all, the integrity of various environmental guide planning is not strong, and the coordination of environment is not enough, and the design concept is not updated. The quantitative production of the guide card is very serious, which neglects the relationship between environment and culture. Especially in many business environments, the design of the guide system is monotonous and lacks the overall consideration of space. The clutter of advertising signs fills the city space, grabs the visual status of the guide and weakens the function. In cultural buildings and squares, the guide design also lacks the embodiment of the cultural connotation and distinctive features of the specific environment. Design practice and theory to study the vertical portal, isolation, lack of effective contact coordination, causing insufficient design concept updating, advertising design and set up and the development of urban construction space cannot be synchronized. The more prominent problem is the lack of system specification, scientific and reasonable and effective guidance system design. Once again, the guidance system indicates that the information is not clear, or even wrong, that is, "information blind area" and "information misunderstanding", which leads to the failure of the navigation system function. The "information blind area" guidance system lacks the coherence of the information instruction, and the interruption in the local area can easily cause people to judge the ambiguity. The "information erroneous zone" instructs the system to refer to the incorrect, ambiguous and ambiguous content of the system, or whether the location is unreasonable, deviant, or the language content is ambiguous, and it is easy to understand the difference. The existence of "information blind area" and "information erroneous zone" can easily lead to people's error of judgment, causing great inconvenience to travel. In the end, the domestic partial guide card chooses the material false and inferior, the service life is short, directly affects the overall environmental quality, causes unnecessary resources to waste. All these problems need to be paid enough attention by city builders and participants to strengthen supervision and management, and actively improve the development environment.

II. Case analysis of public space guide design.

1. Cultural guide design.

Every nation has desire and pursuit of self-realization, are in their own way to express themselves, which makes more and more people aware of the problem of "localization" of the design, the design must be integrated into the local culture in order to get sustainable development. Especially in China, design localization is an urgent problem. The localization of design is not a simple inheritance of traditional Chinese culture -- a simple form of cultural "shape", but the essence of Chinese traditional culture -- "god" is integrated into the design. The so-called "god" refers to the things of thought and spirit. The direct reference to cultural elements, the abstract generalization of cultural symbols, the indirect reference to cultural connotation, are all cultural design embodiment.

Lijiang is one of the most famous tourist cities in yunnan, and its rich cultural connotations make the ancient city extremely bright. Here, guided vision is not only a sign guiding people's direction, but also fully demonstrates the connotation of regional ethnic culture. In the selection of materials, lijiang guide chooses natural and simple wood as the base skeleton, which is integrated with traditional architecture and street space, and is natural and harmonious. In the shape design, the details reflect the national cultural characteristics. In the text design, choose Chinese, dongba wen, English three language use, fully considered the instruction function complete, embodies the humanized design request. The overall form of the unified and local variation of the guide system and the ancient town full of strong folk customs of the commercial storefront integration, showing the unique charm. In this, the guide sees more to become the cultural carrier of the environment.

2. Ecological environmental protection type guide design.

The appearance of eco - friendly guide design makes the guide system achieve a "harmonious symbiosis" relationship with the environment. It is a concept of design that originates from the environment, integrates with the environment, does not damage the environment, and respects the environment. The guide of eco-environmental protection is mainly understood from the theme and material of design, and it is distinguished from the design style. In terms of specific design, it means that the design and environmental coordination coexist, and the impact on the environment is objectively minimal. On the theme, the purpose and content of this kind of guide setting is to encourage people's environmental protection behavior and raise awareness of environmental protection. In the choice of materials, first of all, the use of ecological materials does not harm human beings. The second is the use of natural stone, bamboo, biodegradable materials, etc. In order to save costs, designers usually locate the selection of materials in the local raw materials, these materials are inexpensive, and can be coordinated well with the natural environment, also greatly reduce the transportation cost on cost. Reflected in the choice of color, can coordinate with the overall environment, do not cause visual pollution. Like the newly established tianmu mountain guide, its architectural design is based on the respect of the overall environment, reflecting the humanistic culture, and based on the construction principle of Chinese traditional wooden structure. The guide system and the public infrastructure are all made of wood (carbonized anticorrosive wood), which is very suitable to resist the moisture of the mountain. The color positioning of the whole guide system is dark and dark, presenting a natural sense of simplicity and will not conflict with the environment of tianmu mountain. Its advertising height, width, thickness, colour collocation and text font, size, color and so on before the design is made of human body engineering test, to maximize meet the needs of the tourist's visual and clear guidance. Not only natural and environmental protection, but also contains the history and cultural knowledge of tianmu mountain, and improved the tourist grade of tianmu mountain.

3. Personalized guide design.

Personalized guide design is a kind of design form that contemporary people seek to realize self-worth, and usually pays great attention to the theme of environmental design. But its personality design reflects the relative, the environment entity is restricted a lot. The embodiment of individuality is best understood as being in harmony with the whole environment, and different, having its own connotation.

For example, the design of the guide system of Hong Kong Disneyland is very different. Its design economy consumables not waste, color is rich and colorful, modelling is vivid, easy to recognize. Different theme park, the style of guide design each has its own characteristics, dazzling. It can be said that Disney's guide design is more individualistic and creative than the guide design of any urban space. Its shape is peculiar, the content is varied, the color is rich, the whole feels the myth dream without losing the function. Disney's vision allows people to fully appreciate the limitless scope of creation, and even the conventional facilities can be so colorful. Cognitive, thus it is easy to design is to meet demand without pattern, imaginative art can be in the public facilities, but don't blindly pursue individuality, ignored the essence of things actually do more harm than good.

4. Energy-saving guide design.

Under the influence of eco-environmental protection concept, more and more people realize the importance of low-carbon life to human development. Design is a service, to meet the needs of the people, also need to comply with the public economic level, from the sustainable development strategy to transform the design quality and design the contradiction between the practical and the trend of the change design bold waste. In light of the dimming effect of the night light, people have installed lighting on the guide sign. In Hong Kong, advertising not only consider the needs of pedestrians, and also consider the needs of the driver, guide light emitting devices are installed in the card, the driver in the car at night can see advertising information, the pedestrian access is also very convenient. This design not only meet the guide depending on the direction function, also have the effect of the street lamp, a combination of both, reduced the space of public facilities occupy, reduce visual noise, save material, from cost is to adapt to the sustainable development of the design of the new way of thinking.

At home, we also tried the economical energy-saving design, such as changing the lighting mode as energy-saving lamp, and using solar energy to generate electricity to meet the night lighting of street lamps; The night spontaneous light material was selected for the guide material. Or to reorganize the street lamp, telephone booth, chair and other environmental facilities and guide system. Although such design cases are few at present, the prospect of development is strong, economical and practical.

III. Endnotes

Through the in-depth analysis of the current situation of domestic guide development, the author believes that the following points should be followed in the guide design:

1. The design reflects the harmony between man and nature, and the natural and humanistic landscape features should be fully considered, so that the guide is naturally integrated into the landscape without appearing abrupt.

2. Design reflects cultural connotation. The design of the guide system should refine the cultural spirit of the landscape to help shape and strengthen the regional cultural characteristics.

3. Designed to reflect humanistic care and improve the happiness index. The planning and design of the guide system should not only facilitate people's travel, but also allow people to feel the concern of human nature in the environment, which is helpful for advocating healthy and developing a positive lifestyle.

4. Design must focus on practicality. The design plan of the guide system needs to consider the economic practicality fully, and strictly control the material selection, production method, setting location and other factors, so as to ensure the durability of the guide system. In a word, a successful guide design should be combined with "functionalization and service", and in the form of an aesthetic form, it should reflect the unique characteristics of regional culture.
