Description
Technical field
The utility model relates to technical field of soil remediation, specifically, is repair the green of heavy metals mining area soil to plant structure.
Background technology
Along with developing rapidly of economic globalization, problem of environmental pollution is increasingly serious, and the health of the mankind in positive serious threat, wherein especially serious with the soil pollution by heavy metal in mining area.Be eliminated or scoop away owing to showing soil in mining process, the normally cubsoil stayed after mining or slag, adding the weight of large-scale winning equipment, often make soil hard, harden.Mining area surface collapse forms large-area subsidence basin simultaneously, very easily causes soil to grow salination because phreatic table improves relatively.Mine solid slag in banking process through rain drop erosion, shower, very easily poisonous and harmful element is wherein infiltrated in soil, cause heavy metal content in soil too high, directly pollute the agricultural product be planted near mining area in soil, contaminated agricultural product then can be detrimental to health by food chain.It is reported, the content of beary metal in the high incidence of Jiangxi Residents in Mining Area liver cancer and soil is higher substantial connection.
At present, the reparation of heavy metal polluted soil in mine field mainly adopts physics, chemistry, biology reparation.Phytoremediation be biological prosthetic in one, have that cost is low, effective, application prospect extensively, non-secondary pollution, reclaim after the high feature of ecological benefits.
Utility model content
The purpose of this utility model is to provide a kind of with low cost, and structure is planted in multi-functional the green of reparation heavy metals mining area soil.
For achieving the above object, the utility model provides following technical scheme:
Repair the green of heavy metals mining area soil and plant structure, belong to technical field of soil remediation.Be characterized in: in the ditch of mining area, fill different soil horizons from top to bottom, along ditch planted on two sides greenbelt.Described soil horizon is divided into three layers: underearth is by this rammed earth in the ditch of mining area, and soil thickness is 3 ~ 5m, forms impervious barrier; Spoil layer is piled up by the spoil in mining area and is formed, and spoil layering is piled up, and every layer thickness is 3m; Topsoil covers low unit weight, high porosity, without the clayey soil of degenerating or the high-quality soil adding soil conditioner, soil thickness is 0.8 ~ 1.0m.Described greenbelt is divided into 3rd district: a district is willow greenbelt, and along ditch plantation, shelter strip breadth is 10m, adopts soil moved in improve the original hole to plant, and the initial stage of playing is to filling the blocking of soil layer, shielding action; 2nd district are Eupatorium adenophorum greenbelt, and along the plantation of willow greenbelt, shelter strip breadth is 20 ~ 30m, utilizes its plant heavy metal zinc, lead and measuring copper characteristic absorption accumulation heavy metal; 3rd district are green arbor, shrub greenbelt, intersect and plant, the wide 6m in forest belt along Eupatorium adenophorum greenbelt, as green screen, reduce mining area airborne dust and spread at a distance.
Described willow greenbelt adopts soil moved in improve the original hole to plant, and soil moved in improve the original adopts mellow soil and fertilizer to press 10:1 mixing, and fertilizer adopts sanitary sewage station mud.Described willow greenbelt width is 10m, and array pitch is 1 ~ 1.5m, and spacing in the rows is 0.5 ~ 1m.
Described Eupatorium adenophorum greenbelt adopts cuttage plantation, and greenbelt width is 20 ~ 30m, and array pitch is 0.5 ~ 0.8m, and spacing in the rows is 40cm.
Described green arbor, shrub greenbelt, adopt point row's multirow to intersect intensive plantation, greenbelt width is 10m, and array pitch is 20 ~ 30cm, and spacing in the rows is 10cm.Green arbor selects arbor-vitae wood, and shrub selects rockery first, gold zone plum, camellia tree.
Compared with prior art, good effect of the present utility model is:
1. after implementing the utility model, soil desertification degree reduces, and viscosity improves, and content of beary metal declines, and organic matter increases.Described Eupatorium adenophorum greenbelt heavy metal ZINC IN SOIL, lead, copper segregation are strong, and unit are heavy metal-polluted soil remediation efficiency is high.
2., after implementing the utility model, effectively avoid soil degenerate problem repeatedly.Because the section feature according to natural soils constructs, effect that different soil plays growing process is different, forms nutrient chain capable of circulation between soil layer itself and plant.Topsoil provides the nutrient needed for plant growth, and spoil layer carries out the migration and conversion of moisture and nutrient by the capillary porosity in the soil body and bottom and underground water, underearth lowering of watertable, to alleviate in underground water salinity to the impact of plant growth.Therefore, final-period management only need suitably be turned over to topsoil and apply fertilizer, and saves labour.
