A kind of ecological city system and its construction method

technical field

The invention relates to the field of ecological city construction, in particular to an ecological city system and a construction method thereof.

Background technique

To build an eco-city, it is necessary to maximize the use of natural resources and not cause irreparable damage to natural resources, to establish a low energy consumption, high output, economical and conservation-oriented society, and to form a sustainable development, A benign modern livable urban environment where people and nature live in harmony.

Since modern cities often use impermeable materials such as glazed bricks, cement, and asphalt to lay the ground, the proportion of artificial impermeable ground in the urban area is increasing. Therefore, the expansion of urban artificial impermeable It is divided into two completely different environmental systems from the ground below. For the environmental system above the ground, the drainage system is the main one, which increases the runoff coefficient. Under the same rainfall, the flood peak appears earlier, and the flood peak discharge also increases sharply. When encountering a large amount of rainfall, its flow may exceed the bearing capacity of the urban drainage system, causing urban waterlogging, and posing a greater threat to the urban road traffic system, housing property loss, and urban public health. For the underground environment system, the increase of impermeable ground will cause rainwater to stay on the ground to form surface runoff or flow into rivers through the drainage system. The groundwater cannot be replenished in a timely manner. In addition, industrial production and modern life double the groundwater, resulting in a sharp drop in the groundwater level. Aggravated the city's drought, water shortage, land subsidence and other problems. Due to the barrier of the impermeable ground, when a large amount of rainwater falls on the ground, it can only flow away in vain. At the same time, the soil layer under the impermeable ground and the soil layer in the green belt cannot get enough water for a long time. The ground rainwater supply causes water shortage. For the vegetation in the green belt, it is often necessary to use additional sprinkler equipment for water supply, resulting in a large consumption of urban water resources.

In order to improve the adverse effects caused by laying artificial impermeable ground on a large scale in cities, it is inevitable to improve the urban water ecological environment by introducing rainwater into the urban underground soil, restoring the original ecosystem, taking measures to replenish groundwater, and at the same time reducing the pressure on urban drainage. way. For urban construction, the ground rainwater seepage system can be pre-buried under the hard pavement of urban roads and squares to reduce the impact on the original land and natural environment, which is conducive to the creation of green cities and ecological cities.

In addition, the planning of industrial areas and residential areas in modern cities is not reasonable, resulting in the mixed gathering of enterprises in industrial areas, which is not easy to classify and supervise. Pollution and interference, the rational division of different urban functions into different regions is conducive to improving the efficiency of urban operations and reducing mutual interference between different regions.
