Third, the overall planning ideas 1. The overall image of the ancient city of China —— the university "city" draws lessons from the prototype of the grid layout of the ancient city of China, and adopts the pattern of eccentric axis symmetry, which embodies the oriental culture and the theme of "city". 2. Ecological duckweed-Lotus originated in China, and has a relatively dispersed and independent group structure. It is famous for its good relationship with the environment, and is loved by the world with its holy and beautiful image and profound cultural connotation. The overall planning concept of Guangzhou University Town draws lessons from the growth mode of lotus, and adopts the architectural layout mode of overall dispersion and local concentration, just like the blossoming lotus floating in the green ocean, which is in harmony with the natural environment and protects and exerts the ecological function of "green heart" to the maximum extent. 3. Nervous system)-The network structure consisting of function, structure, road and management is the most complex material structure on the earth. The main functions of the human nervous system are to receive and process various sensory information inside and outside the body, regulate and influence the movements of the body and internal organs, maintain the relative stability of the internal environment, initiate and control various behaviors, and manage advanced functions such as learning, memory, emotion, thinking and language, as well as the central nervous system. In the overall planning concept of Guangzhou University Town, we learn from the network structure characteristics of nervous system, understand the structure and function of Guangzhou University Town as the central intellectual area and information center system of the city in a more general sense, and try to form a clear overall spatial framework with linear network order and create a dynamic internal functional organization. 4. Spacecraft-the high-tech symbol of soaring. The overall planning model is consistent with the shape of the spacecraft. The * * * enjoyment area in the central city is an empty metaphor for the residents and citizens of the university town, while the campus areas on both sides are like two unfolded solar panels, which provide energy and information for the university town at all times and endow Guangzhou University Town with high-tech connotation; And expressed the ambition of Guangzhou University Town to take off in the new century. Fourth, the concept of the master plan, the overall order model diagram, considers the uncertainty of the university. The concept of master plan adopts the combination of "rigid structure" and "flexible structure" to actively adapt to the requirements of the change of higher education industry in Guangzhou University Town. "Rigid structure" refers to the relatively stable skeleton in the planning and layout, which will not change with the introduction of colleges and universities. Its contents mainly include main roads, interval main roads, urban resource enjoyment areas and pilot production areas. "Elastic structure" refers to the elastic structure that changes with the change of higher education industry market, including elastic land, living quarters and secondary roads in various university parks. This plan is based on the actual situation of Guangzhou, combined with the terrain, and under the guidance of planning objectives and design concepts, a frame-type spatial structure model is put forward, and on this basis, a variety of different university organizations and layout schemes are developed to adapt to the uncertain factors of the market. 5. The overall order pattern adopts the method of grid and module overall design, organically connects all functional units with a regular and orderly road system network, and creates a spatial rhythm with a sense of order. At the same time, the reserved mountains and curved green ecological spaces are interspersed as active elements, which embodies the philosophical concept of the unity of opposites between "freedom" and "rules" in modern society. The layout of campus land of intransitive verbs The campus land of university town forms a three-level structure, namely the secondary college of university town campus. The university park consists of several universities with similar nature. There are four university parks in the North District (including the relatively independent international university park in the West District) and two university parks in the South District. The determination of the nature of colleges and universities in each park should fully consider the existing functions and location conditions of adjacent areas. For example, the nature of the park near Guanzhou International Biological Island should be combined with the biological theme, and the university park near the ecological agriculture protection zone in the southwest corner of the southern district should choose agriculture and forestry universities, and the agricultural protection zone can be used as its experimental base. The combination of international university parks adopts the way of "combination of reality and reality". On the one hand, it attracts international famous schools to set up branches or offices, on the other hand, it should give play to the distance education function of virtual universities. The construction of university campus advocates resource sharing. In accordance with the principle of "mutual benefit, voluntariness and contribution to academic exchanges", it is suggested that some academic resources, life service resources, sports resources and public education resources, such as university-level libraries, restaurants, canteens and stadiums, should be properly concentrated to form a relatively concentrated inter-school resource sharing area, and each university should be responsible for the construction of 65438. Focusing on the uncertain factors of the market, the spatial layout adopts the "flexible structure" system and puts forward different university spatial organization modes such as "belt", "center" and "group" to adapt to the development and changes. Seven. The hierarchical structure of * * * Resource University City provides three kinds of * * * resources with different degrees of openness, which not only ensures the enjoyment of resources, reduces investment, expands communication, but also ensures the relative independence and integrity of universities. The first-level * * * enjoyment of resources refers to the * * * enjoyment area of urban resources; The second level includes inter-school resource sharing area; The third-level * * * resources include the secondary college area in the university campus. Eight. Living area * * * Enjoy the facilities structure. The living quarters in the university city are industrialized to solve the living and living problems of most teachers and students in colleges and universities. In space, the group layout mode is adopted, and public facilities and public green spaces are provided respectively according to service units. Student apartments pay attention to the closure of space and promote exchanges between students. Structure diagram of greening landscape system. The greening ecological structure system strengthens the overall function of the "green heart" of the city. On the basis of ecological sensitivity evaluation of land use, an open reticular greening ecosystem is adopted to form a green grid with "two hearts, two axes, four rings, five corridors and six cores" to create a landscape ecological security pattern. Strengthen the organizational function of green space, organize public facilities and living facilities with various forms of public green space as a link, form a green urban outdoor recreation space sequence, and realize the ideal of "returning to nature" for mankind. Two hearts-strictly control the mountain forests and agricultural ecological protection areas in the north and south areas of the university town, as the "green hearts" of the two areas of the university town. Two axes-give full play to the ecological function of the central part of the Pearl River waterway in the north-south region as the "blue axis", and emphasize the greening ecological function of the main axis of the north-south intercity function as the "green axis". The Fourth Ring Road-the combination of north and south areas, the main rivers and highway protection belts, and the circular greening of transit form an ecological barrier. Five corridors-Combining the water system and the dominant wind direction, five green corridors are set up in all parts of the Pearl River to strengthen the ecological connection between the university town and the Pearl River, forming an overall situation of embracing the Pearl River, which not only draws wind to dissipate heat, but also attracts people to the river and returns to nature. The six-core group public green space is arranged in each main functional unit, forming six "green cores". 10. Waterfront shoreline utilization gives full play to the advantages of long coastline of university town, highlights the image of "island", and properly handles the relationship between shoreline function and landscape. In the planning, people's activities are led to rivers to realize ecological life. Combined with the functional organizations along the Yangtze River, cultural facilities belts and green leisure belts are set up respectively. Various small-scale cultural activities facilities are arranged in the cultural facilities area to provide riverside cultural activities places for students and teachers; Green leisure belt provides various leisure and fitness activities, such as walking, talking and jogging. In combination with the good environment of riverside, arrange a centralized large-scale sports facilities area and large-scale sports venues for local people and urban residents to use, and even serve as the main venue of the Universiade; At the same time, it can also be used as a landmark building along the river in the university town, enriching the skyline along the river. At the same time, the planning should pay attention to handling important landscape nodes along the river, such as the island tail, which is not only a good viewing point, but also a landscape focus of external attention. In addition, in combination with functions and transportation, a number of docks are set up along the river to meet the connection between life and campus. XI。 Internal traffic organization mode The internal road system in the north and south areas of the university town is relatively independent, and the main roads are closely connected through the river-crossing tunnel (which is merged with the subway line to cross the river). The road networks in the two districts are in the form of grid and radiation, which not only ensures the squareness of plots and the order of traffic, but also provides extremely convenient pedestrian contact and the integrity of landscape organization. The roads in the university city are clearly classified, and the functional areas are connected with each other through main roads and interval main roads, and the interior of each unit is connected through secondary main roads. The university town advocates the policy of giving priority to public transportation and bicycles, and adopts the public transportation system for inter-school and life contact. Among them, Xiaoguwei Island proposed to set up a two-way public transportation line combining inter-school resources and residential units to facilitate teachers and students to travel and communicate; At the same time, the characteristics of bicycle traffic are fully considered in road design. The cross-shaped subway is equipped with main roads and urban resources, which attracts and facilitates more people to use and is conducive to traffic evacuation. The subway station is equipped with large-scale public facilities and living quarters. Planning advocates the mode of separation of people and vehicles. Macroscopically, try to separate people and vehicles and set up fitness trails around the island; In each functional unit, the mode of separation of people and vehicles is adopted to ensure the smooth traffic of shops and pedestrians. Twelve. External traffic system structure External traffic organization is divided into two levels. First of all, make full use of the transit expressway and expressway, and set up interchanges in the north-south area and the east-west side of the university town to connect with the internal trunk traffic system. Secondly, the internal trunk roads are directly connected with the surrounding urban functional areas, such as Guangzhou New Town, Guanzhou International Biological Island, cheung chau island Historical and Cultural Protection Area and Haizhu District, forming a secondary urban trunk road network. In addition, make full use of the transit of Metro Line 4, and consider the continuity of urban residential groups along the south bank of the Pearl River (such as South China New City, Agile Residential Group and Xinghewan Residential Group). ), it is suggested to set up a subway along the river to connect Guangzhou Economic Development Zone, strengthen the connection between the radiation capacity of university town and science and technology industry, and form a landscape environment of "one river and many banks" in Guangzhou.
