Abstract
The invention discloses a method for constructing a waterfront vegetation zone for filtering non-point source pollution. The method is characterized by comprising the following steps: a) setting ecologic interception nets at high positions on sloping surfaces of natural gentle slopes of rivers and lakes in a densely populated area of a waterfront zone, and supporting the ecologic interception nets by adopting small timber piles; b) planting relatively large, thick and strong emergent aquatic plants between normal water level positions on the sloping surfaces of the natural gentle slopes of the rivers and lakes in the densely populated area of the waterfront zone and the ecologic interception nets at the high positions, wherein the emergent aquatic plants are distributed in a stripped manner, and the distributing direction is vertical to a water flow direction; and c) planting flooding-tolerant emergent aquatic plants with a suitable growth depth of 40cm or above below the normal water level of the sloping surfaces of the natural gentle slopes of the rivers and lakes in the densely populated area of the waterfront zone, wherein the emergent aquatic plants are distributed in a stripped manner, and the distributing direction is vertical to a water flow direction. The method for constructing the waterfront vegetation zone for filtering non-point source pollutions, disclosed by the invention, is suitable for water systems of the natural gentle slopes of the rivers and lakes in the densely populated area of the waterfront zone.
Description
Technical field
The present invention relates to a kind of water ecology reparation, particularly relate to a kind of riparian plant band for filtering pollution of area source
The method built.
Background technology
Along with expanding economy and the quickening of Development of China's Urbanization, people are more and more deep for the cognition of ecological environment,
Restoration of the ecosystem is badly in need of wanting in the rivers and lakes of dense population areas, recovers view and the amusement function in river course, and the river in suburb, lake are suddenly
Needing to repair the ecological environment having been subjected to destroy, therefore, river, lake even basin has been carried out in China's majority area in recent years
Ecological management project, wherein the restoration of the ecosystem of waterfront band is an important ring, how by aquatic the planting of reasonable construction waterfront band
Thing becomes the water correction of water body and plays the important means of landscape function.
Summary of the invention
A kind of method that the invention aims to provide riparian plant band for filtering pollution of area source to build, it is not only
Can be effectively realized the restoration of the ecosystem in the river in band dense population areas, waterfront, lake, and can also recover river course view and
Amusement function.
The present invention is realized in achieve the above object: a kind of shore for filtering pollution of area source of the present invention
The method operation that water vegetational zone builds is as follows:
A) the river of band dense population areas, waterfront, lake natural gentle slope domatic on eminence ecological intercepting net is set, and adopt
With small-sized timber supporting；
B) the river of band dense population areas, waterfront, lake natural gentle slope domatic at residing ordinary water level with eminence set by
Ecological intercepting net between plant the emergent aquactic plant that plant is more sturdy relatively greatly, and be distributed in ribbon, distribution arrangement and current side
To vertically；
C) the river of band dense population areas, waterfront, lake natural gentle slope domatic plant resistance to water logging under residing ordinary water level
The emergent aquactic plant more than suitable raw degree of depth 40cm, and be distributed in ribbon, distribution arrangement is vertical with water (flow) direction.
The described river in band dense population areas, waterfront, the natural gentle slope in lake are that slope is refuted than 1:3 and more slow soil property
Bank.
Described ecological intercepting net is high density polyethylene (HDPE) net, the aperture 20-30mm of described ecological intercepting net, and height is 18-
22cm。
The relatively big more sturdy emergent aquactic plant planting density of described plant controls at 5-10 strain/m2, plant is more sturdy relatively greatly
Emergent aquactic plant kind is Canna generalis Bailey, again power flower, Arundo donax or short cattail and reed plant.
Described resistance to water logging, the emergent aquactic plant planting density more than suitable raw degree of depth 40cm is 20-40 strain/m2, resistance to water logging, suitable raw
The emergent aquactic plant kind more than degree of depth 40cm is with Mugil cephalus grass, Hai Shouhua, Rhizoma Iridis Tectori or calamus plant.
The method that a kind of riparian plant band for filtering pollution of area source of the present invention builds, mainly at waterfront band population
The river of compact district, natural gentle slope domatic in lake the most successively high density polyethylene (HDPE) net is constructed ecological intercepting net,
The emergent aquactic plant cultivation using plant more sturdy relatively greatly builds and forms preliminary filtration system and use suitable raw degree of depth 40cm of resistance to water logging
Above emergent aquactic plant cultivation builds and forms depth-type filtration system.
The present invention a kind of for filter pollution of area source riparian plant band build method have in actual use with
Lower advantage:
1, the method that a kind of riparian plant band for filtering pollution of area source of the present invention builds, in band dense population areas, waterfront
River, the domatic upper eminence on natural gentle slope in lake arrange wide-aperture ecological intercepting net, and use small-sized timber supporting, macropore
The ecological intercepting net in footpath intercepts floating thing, fallen leaves and other the impurity rubbish etc. in rainwash.
2, the method that a kind of riparian plant band for filtering pollution of area source of the present invention builds, in waterfront, band is densely populated
The river in district, lake natural gentle slope domatic residing ordinary water level at and eminence set by ecological intercepting net between plant and plant
The emergent aquactic plant that strain is more sturdy relatively greatly, and be distributed in ribbon, distribution arrangement is vertical with water (flow) direction, to filter out rainwash
Middle large particulate matter and partial suspended thing.
3, the method that a kind of riparian plant band for filtering pollution of area source of the present invention builds, in waterfront, band is densely populated
The river in district, lake natural gentle slope domatic residing ordinary water level under plant the very water of more than suitable raw degree of depth 40cm of resistance to water logging
Plant, and be distributed in ribbon, distribution arrangement is vertical with water (flow) direction, filters out the little granule in rainwash with deep purifying
Material, the most also nutrient substance in depth-type filtration water body, it is achieved the deep purifying of water body, thus play the mesh of protection water body
's.
The method that a kind of riparian plant band for filtering pollution of area source of the present invention builds is applicable at waterfront band population
The river of compact district, the water system on natural gentle slope in lake.
