Greening project refers to the introduction, construction and management of vegetation to create an environment with ecological, aesthetic and humanistic benefits for regional life. Greening projects can improve the ecological environment, enhance the regional landscape, improve air quality, reduce temperature, increase the infiltration of precipitation and reduce soil erosion.
Under normal circumstances, greening projects are roughly divided into urban greening projects, greening subsidiary distribution projects and other projects.
Urban Greening Project:Including greening division, large tree transplantation division, vertical greening division and greening subsidiary division. Greening Ancillary Division Project:This is a project that includes rockery stacked stones, garden road paving, general garden road, stepping steps, pebbles, grass brick installation, garden water supply and drainage, flower bed facilities and small retaining walls.
Engineering technology of garden construction:These technologies include earthworks for terrain transformation, mountain digging and stone engineering, garden water management engineering and garden revetment engineering, fountain engineering, garden water supply and drainage engineering, garden road engineering, planting engineering, etc.
The project cost of greening projects is quite different from the cost of general civil engineering and housing construction, and a number of factors need to be considered. Generally speaking, the cost of greening projects includes eight parts: seedling budget price, planting fee, survival rate maintenance fee, management fee, profit, independent fee, seedling price difference and tax. Among them, the budget price of seedlings is the basis for taking fees, including nursery storage price, excavation fee, mud ball bandaging fee, hoisting fee, transportation fee, transportation loss, unloading fee, planting loss, procurement fee, plant quarantine fee and seedling operating profit.
The planting fee includes the planting of seedlings and lawns, as well as the removal and transportation of garbage and waste after planting. Big tree planting also includes the cost of hoisting machinery. The maintenance fee during the survival rate period includes the cost of straw rope around the trunk, the cost of conventional support, the cost of shade canopy, the cost of flexible snorkel, the cost of labor, the cost of water and electricity, etc. The management fee includes the cleaning and transportation of construction waste and other obstacles within the scope of the project, the excavation or cutting of the roots of the original seedlings within the scope of the project, the excavation of turf or the removal of turf, the soil ball bandaging or pulping, pruning, ponding, loading and handling of the original seedlings after excavation, waste transportation, site clean-up, sorting out the greening land fee, planting soil, nutrient soil, earthwork modeling, earthwork transportation, special support and water and electricity fees in planting and maintenance.
In the greening project, plants that adapt to the local climate and soil conditions are selected for cultivation, and through scientific and reasonable design and planning, the plant composition is reasonable, rich and diverse, and reasonable planting, management and maintenance are carried out. The implementation of the greening project requires the participation of enterprises, institutions and residents, and jointly promotes the development of the greening project through cooperation and investment of capital, manpower, material resources and other resources.
