According to the rapid opening of industries and other fields, China ’s ecological environment has gradually encountered problems such as the decline of groundwater levels, deterioration of the water ecological environment, and water pollution. Therefore, the State Council announced the “Counseling Opinions of the General Office of the State Council on Promoting the Construction of Sponge Cities,” which requires In the process of urban construction planning, we should give full play to the ecological system conditioning functions of construction, green, and roads. In order to create an outstanding ecological space, a university school as an independent system should absorb the sponge city planning concept and plan and transform the existing school scene in order to ease the ecological crisis. The following is a detailed discussion of the scene planning of sponge schools.

Sponge school concept

As an independent system, university schools have received the attention of urban construction operations. That is, under the guidance of the sponge city theory, the construction of sponge schools has been gradually proposed. The sponge school refers to that the entire university school is like a sponge, with certain flexibility and the ability to adapt to environmental changes. . For example, when encountering natural disasters, you can rely on your own resilience to collect and release rainwater, and reasonably plan the water absorption, storage, seepage, and clear water treatment procedures during rainfall. When the school ’s water resources are scarce, release the storage in a timely manner. Store water, and ultimately improve the ecological environment of colleges and universities. In addition, the sponge school concept broke through the traditional school construction thinking in the process of proposing, and proposed the integrated planning of infiltration, stagnation, storage, cleanliness, use, and drainage. Then, through the rational application of rainwater resources, the school ’s water ecology was restored. Together, the construction The aquatic basic equipment based on scenes creates an outstanding school scene environment. However, during the sponge school scene planning, in order to conform to the sponge school theoretical thinking, outstanding human-oriented planning criteria are needed, that is, to stand on people's aesthetic habits, natural mental needs and other perspectives, to explore the characteristics of school civilization, and adhere to the rational layout of Joe, irrigation, grass, etc. , Reflecting the characteristics of multi-level scene planning, and relying on green sceneries to create outstanding aquatic ecological spaces.

Sponge school scene planning approach

1. Zoning planning In the process of Xuchang school scene planning, in order to distinguish the sponge school planning concept, it attaches importance to reaching infiltration, stagnation, storage, net, use, drainage and other environmental construction intentions through zoning planning methods. The Xuchang School scene plan mainly includes the planning of Yingjie Park, Siguyuan, etc. In the meantime, the Yingjie Park scene is mainly embossed with water curtain walls, and it attaches importance to reflecting the history of Xuchang celebrities. Together, in order to plan the characteristics of water civilization for an outstanding scene, a water weir was planned on the top of Yingjie Park, and then the dynamic nature of the water scene attracted people's attention. In addition, during the planning of the hometown area of Xuchang College, I studied the traditional thinking of "the wise men enjoy the water and the benevolent people enjoy the mountain", condensing Xuchang's prehistoric civilization into a landscape civilization, that is, setting up a pool in the center of the hometown, with a rockery on the north side The pavilion corridor is on the east side and the gentle slope is on the south side, full of green bamboo, and then through the scene of water, stone, pavilion, etc., it is thought-provoking and meets the planning requirements of the sponge school. In addition, during the planning process of the 10,000-square-meter nursery garden in Xuchang College, flower beds, bonsai, and bonsai were planned, and basic equipment such as greenhouses were placed together to create an outstanding scenery environment.

From the above analysis, it can be seen that through the zoning planning of Yingjie Garden, Siguyuan, Nursery Garden, etc., it is possible to rationally plan water resources seepage, stagnation, storage, and netting operations according to the different needs of water resources in each region to prevent The problem of water resources corruption, outstanding sponge school planning ideas.

2. Reconstruction Planning of Scenery Water System Pipe Network In order to invent outstanding water ecology in the planning process of Xuchang College's sponge school, it is also necessary to pay attention to the reconstruction plan of scene water system pipe network system. During the reconstruction of the landscape water system, first of all, the characteristics of the school environment appearing high in the north and low in the south should be considered. The southern area should be used as a water storage area, with the lake scene belt as the center. Then, sewage pipes and artificial reservoirs should be added. , Rainwater pipelines and other basic equipment to rationally seep, store, clean, and drain water resources in schools. Together, based on the complete set of basic equipment, artificial reservoirs and rainwater pipelines need to be connected with the school's water collection system. Then, when water resources in the lake scene belt are lacking, the artificial reservoirs should be launched in a timely manner. Compensate and complete the supply of oasis water, daily water, and landscape water to achieve the best water use. Secondly, in the process of transforming the scene water system, attention should be paid to the discharge of school sewage and excess rainwater to municipal sewage pipelines, that is, to ensure the recycling of water resources through timely discharge of school sewage, and to create an outstanding aquatic ecological environment. .

3. Oasis System Reconstruction Planning During the planning process of the sponge school in Xuchang College, the opening of the oasis system reconstruction planning process must be started from the following levels:

At the top of the list, in the process of planning the oasis system of roofs, roofs, bay windows and other teaching buildings, a large number of flowers and plants need to be cultivated to improve the school's greening rate. Together, through roof pots, roof sheds, roof oasis, and houses The planning of the top garden, etc., compensates the oasis area occupied by the construction.

Second, in the planning process of Xuchang College's school scene, because the square area occupies a large area, it is necessary to add a green belt mainly in the square space. For example, during the planning of the school gate oasis system, if the terrain is flat, it will affect the collection of rainwater and cause the problem of water loss. Therefore, you can learn the concept of concave-convex planning, and set up an oasis system in the flat area of the school gate. After all, through the planning method of the concave water collecting belt, accelerate the absorption of water by surrounding plants, and ensure that rainwater enters the ground, improve the groundwater environment, and invent outstanding schools. Ecological space, in the planning, we must pay attention to make steep and appropriate planning based on the terrain.

Thirdly, in the process of reforming the oasis system of the rainwater garden and planting grass ditch, in order to enhance the flexibility of the school's ecological environment, it is necessary to adopt the sinking oasis resettlement method of the rainwater garden on both sides of the road, thereby slowing the flow of rainwater in the oasis. Finish rainwater storage and other operations. Together, during the collection and use of rainwater in schools, it is also necessary to add water collection equipment, water storage equipment, etc., in order to cooperate in the orderly opening of rainwater treatment operations.

4. Pavement Pavement Reconstruction Planning During the school landscape planning process of Xuchang College, the reconstruction plan of the pavement can also reach the planning intention of the sponge school. For example, during the school sidewalk reconstruction planning process, in order to satisfy the school's water ecological construction requirements, it must be adopted. The pervious paving is the main construction method, and the drainage of the remaining sewage is completed by the paving method of inverted trapezoidal floor tiles. During the planning of school motorway reformation, in order to facilitate the seepage of rainwater, we need to use seepage bricks to lay the school motorway. Together, we need to set a drainage outlet on the stone along the pavement road so that the remaining rainwater flows away from the drainage outlet. In addition, during the reconstruction of the school's sidewalk, the overall height of the oasis should be about 50-100mm lower than the roadside stones. Together, a ditch should be set up between the oasis and the roadside stones. Then, when rainwater passes through the roadside stones, it can enter the ditch. At this point, the intention of water purification was reached. In addition, during the school parking lot planning and planning, in order to preserve the sponge school planning concept, attention should be paid to the selection of grass planting bricks or permeable bricks during the paving process in the area, in order to complete the conditioning of the school's surface humidity and reach the best school water ecological planning. And prevent the lack of water resources from being highlighted.

To sum up, the traditional school scene planning concept can no longer satisfy its sustainable opening requirements. Therefore, in order to maintain the balance of the school's water ecology, attention should be paid to the sponge city concept as a guide. During the scene planning process of the sponge school in Xuchang College, the pavement pavement reconstruction plan, the oasis system reconstruction plan, and the landscape water system pipe network system reconstruction plan were optimized to optimize the school scene. Together, the rainwater collection was completed during the rain. Then, when the scene environment and water resources are scarce, timely resource compensation will be performed, and an outstanding scene space will eventually appear.
