Description
Technical field
The utility model belongs to massif recovery technique field, repairs more particularly to a kind of massif based on sponge ecosystem
Complex system.
Background technique
In recent years because of the quickening of development & construction and urbanization speed, the contradiction of urban construction and ecological protection is caused increasingly
Aggravation.During the infrastructure constructions such as highway, railway, water conservancy and municipal administration, a large amount of level lands Wa Shan, quarrying take soil, both destroy
Topography and geomorphology and natural vegetation, and form numerous using bare side sloping as the massif crushed zone of main feature, this protects water and soil
It holds and ecological protection, urban landscape and living environment produces totally unfavorable influence, therefore, bare side sloping and massif are lacked
Mouth is administered and is afforested and beautified extremely urgent.
Currently, the main method of slope greening and mountain collapse ecological management is to carry out vegetation weight using thick-layer spray seeding technique
It builds and restores, i.e., prepared dedicated substrate is equably injected in exposed side slope using hydroseeding equipment, formed one layer both
The loose ventilative artificial soil for having some strength and fertility again.The key link of spraying and seeding afforesting is to spray preparation and the plant of matrix
The selection of seed.
The selection of domestic and international greening backing and proportion are different according to reality, and substrate proportion is ecological vestige
Core, the developed countries such as America and Europe, Japan have developed suitable substrate according to conditions such as weather, the hydrology of respective their location and match
Than, such as the technology of Japan's research and development is only suitable for precipitation in 1200mm or more warm humid climate, it is not applicable in China's most area.
China has had been developed that the conditions such as some regional climates in several suitable China, the hydrology, the soil texture since introduction of foreign technology
Substrate, but show the following aspects there are many problems in practice:
(1) high expensive of substrate influences the utilization and popularization of ecological vestige
The substrate of ecological slope protection is that slope greening is successfully crucial.The formula materials of substrate are many using external import at present
Material holds at high price, and the proportion of formula materials is also mechanically using external fixed mode.In addition to this, these imports
Material is to climate in china, and floristic suitable situation is also up for further studying.In fact, some materials in substrate are complete
Domestic replacement can be used entirely, and price only has 1/4 of import or so.
(2) formula of substrate is stereotyped, affects the effect and the acceptance of work of ecological slope protection
The substrate formula implemented at present does not adapt to differently band, Geological Engineering condition, soil types and vegetation adaptability
The requirement of equal ecological environments, the cultivation of Plants types choice especially therein and cooperation advantage group is without it can be considered that weather
Expected ideal effect is often not achieved in condition, soil types, geological conditions, the gradient, the ecology element such as slope aspect (Schattenseite or tailo)
Fruit.
(3) vegetation engineering technology does not adapt to differently matter, rock and soil, the gradient and domatic needs
In unit in charge of construction's implementation process, construction technology is single, be unable to adaptation to local conditions, adapt to different geology, rock and soil,
The gradient and domatic requirement, construction quality is unstable, also influences the effect of slope greening to a certain extent.
Therefore, in order to solve the above problem it is necessary to research and develop a kind of spraying sowing substrate, making it not only has good slope protection
Effect, and cost reduces, it is resourceful.
