Soil disturbance and restoration: During the construction process, operations such as excavation and landfill will inevitably disturb the native soil. If the traditional construction process is excessively disturbed, it may destroy the natural structure of the soil, resulting in a decrease in soil fertility and poor air permeability. For example, frequent rolling of large machinery will cause the soil to compact. The use of refined construction technology, such as small equipment combined with manual excavation, can reduce the damage to the soil. Timely soil improvement after construction and the addition of organic fertilizers will help the rapid recovery of the soil ecosystem and provide a good foundation for plant growth.
Plant planting method: The plant planting process of the ecological retaining wall directly affects the survival rate and growth of plants. Reasonable planting spacing and depth are crucial. For example, the use of precise fixed-point planting technology ensures that plants have sufficient growth space and nutrient acquisition range. At the same time, choosing the right planting time, such as planting during the dormant period of plants or before the rainy season, can improve the survival rate of plants, promote the rapid establishment of plant communities, and enhance the stability of the ecosystem.
Drainage system construction: The construction quality of the drainage system during construction has a significant impact on the ecosystem. Poor drainage can lead to water accumulation in the soil, causing plant roots to lack oxygen and rot, affecting plant growth, and even causing retaining wall collapse. Scientific construction technology requires precise setting of drainage slope and drainage hole location. For example, the method of laying drainage materials in layers can ensure the efficiency and stability of drainage, maintain suitable soil humidity, and create a good living environment for plants and soil microorganisms.
Material laying order: ecological retaining wall is usually composed of a variety of materials, such as stones, geogrids, vegetation blankets, etc. The laying order of these materials will affect the function of the ecosystem. For example, laying geogrids first to enhance structural stability, then laying planting soil, and finally covering vegetation blankets can provide a good implantation environment for plant seeds and promote plant germination and growth. The correct laying order helps to build an organic whole so that each material can play its own role in the ecosystem.
Construction time and season: The choice of construction time and season has an important impact on the establishment of the ecosystem. Construction in the peak season of plant growth may cause great damage to the existing plant communities in the surrounding area. Choosing to construct in winter or during the dormant period of plants can reduce interference with plant growth. At the same time, avoid large-scale earthwork construction in the rainy season to prevent soil erosion, which is conducive to the natural recovery and establishment of the ecosystem.
Protective measures during construction: Taking effective protective measures during construction, such as setting up fences and covering dust nets, can reduce the pollution and damage to the surrounding ecological environment caused by construction. Prevent construction dust and construction waste from entering the surrounding water bodies and soil, and protect the living environment of surrounding animals and plants. In addition, for rare plants or animal habitats found during construction, take measures such as migration protection to maintain the integrity of the ecosystem.
Maintenance and management after construction: Maintenance and management after construction is a key link in the establishment of an ecosystem. Regular watering, fertilizing, pruning plants, and timely cleaning of weeds and pests and diseases can promote the healthy growth of plants and accelerate the succession and stability of the ecosystem. For example, in the early stages of plant growth, increase the frequency of watering to ensure that the plant roots fully absorb water, improve the survival rate, and lay the foundation for the long-term and stable development of the ecosystem.
