Abstract

A method for making the slope of bank green in the water level varying region includes such steps as using flexible ropes and floating substance to make floating beds, using flexible ropes to tie said floating beds to the position on bank slope, where the highest water level is possible, and attaching the plants onto said floating beds.

Description

The greening method of fluctuation in stage region shore slope

Technical field

The present invention relates to a kind of greening method, particularly relate to the greening method of fluctuation in stage region shore slope.

Background technology

In the prior art, all be the bank slope greening that realizes waters fluctuation in stage band by the plantation emergent aquactic plant.But the plant height of emergent aquactic plant is all very limited, and emergent aquactic plant also can be dead when its whole plant is submerged in the water for a long time.Therefore, this greening method only can be used for the greening that the fluctuation in stage amplitude is little or flood the fluctuation in stage region shore slope that cannot not last longly.

Summary of the invention

The object of the present invention is to provide a kind of method of fluctuation in stage region shore slope greening, to satisfy various different fluctuation in stage amplitudes and the various different needs that flood fluctuation in stage region shore slope greening under the situation of lasting.

The object of the present invention is achieved like this: the object that can swim in the water surface with tightrope connects into floating bed, with pull in to shore side bolt the bank at peak level place of tightrope with floating bed, the offshore side of floating bed can be with the fluctuation of water level free lifting, with rope or simultaneously with rope and the stake floating bed is fixed along water (flow) direction, then with plant attaching on floating bed.Like this, water level rises when high, and floating bed swims in the water surface under buoyancy function, unlikely dead by water logging attached to the plant on the floating bed; When water level fell, floating bed was resting on the bank slope that has surfaced with drop in water surface under the effect of gravity, and the bank slope that surfaces is afforested.

Adopt the bank slope in this method greening fluctuation in stage district, neither be subjected to the restriction of fluctuation in stage amplitude, also do not flooded the restriction that lasts length, and less demanding to the plant variety of being planted.

This greening method can be used for the bank slope greening that there is the waters of fluctuation in stage on rivers, lake, reservoir, the pool, weir etc.

Embodiment

Embodiment one: with plastic ties plastic foam plate, floating drum, short bamboo bar etc. are connected into the rectangle floating bed, wherein, short bamboo bar is parallel to the minor face of rectangle floating bed, also is parallel to the bank slope in waters.Tack the minor face of the side of pulling in to shore of floating bed with plastic ties, the other end bolt of rope is on the bank slope that is positioned at the peak level place, and the side of pulling in to shore that the length of rope is in floating bed when the highest with water level makes the long limit of floating bed vertical with the bank slope in waters near bank slope degree of being.With plastic ties adjacent rectangle floating bed is fused, so that form a continuous floating bed band parallel with bank slope along the bank in waters.Simultaneously, at a certain distance with rope or simultaneously with the stake and rope floating bed is held along water (flow) direction, drift about along water (flow) direction to prevent floating bed.Plantation climbing plants such as Chinese wistaria, ivy, caulis lonicerae etc. on the bank slope that is positioned at more than the peak level, and the ground stem of the climbing plants of being planted is sought connections with on floating bed.Like this, water level rises when high, and floating bed is subjected to buoyancy function and swims on the water surface, and the cauline leaf of seeking connections with the climbing plants on floating bed is unlikely dead by water logging; During water level depression, floating bed because of the effect of gravity with drawdown, when drawdown to a certain degree the time, floating bed just rests on the bank slope that has surfaced, the climbing plants cauline leaf of seeking connections with on floating bed covers the bank slope that was not had by water logging, and the bank slope that was not had by water logging is afforested.

Embodiment two: with plastic ties with plastic foam plate, floating drum, short bamboo bar etc. connects into the rectangle floating bed, wherein, short bamboo bar is parallel to the minor face of rectangle floating bed, the bank slope that also is parallel to the waters. tack the pull in to shore minor face of side of floating bed with plastic ties, the other end bolt of rope is on the bank slope that is positioned at the peak level place, the length of rope is in the side of pulling in to shore of floating bed when the highest near bank slope degree of being with water level, make the long limit of floating bed vertical with the bank slope in waters. with plastic ties adjacent rectangle floating bed is fused, so that the bank along the waters forms a continuous floating bed band parallel with bank slope. simultaneously, at a certain distance with rope or floating bed is held along water (flow) direction with rope with stake simultaneously, drift about along water (flow) direction to prevent floating bed. on the plastic foam plate of forming floating bed, beat the hole that some penetrate, and in these holes the plantation hygrophyte as bengal dayflower herb etc. like this, water level rises when high, floating bed is subjected to buoyancy function and swims on the water surface, and the plant of being planted on the floating bed is unlikely dead by water logging; During water level depression, floating bed because of the effect of gravity with drawdown, when drawdown is arrived to a certain degree, floating bed just rests on the bank slope that has surfaced, the root system of institute's plant species stretches into continued growth in the bank slope earth that has surfaced on the floating bed, its cauline leaf then covers on the bank slope that was not had by water logging, makes the bank slope that was not had by the water logging green clothing of putting on, thereby reaches the purpose of fluctuation in stage region shore slope greening.

Claims

1. the greening method of fluctuation in stage region shore slope, it is carrier with the floating bed, to be green plants, it is characterized in that attached to the plant on the floating bed: it with tightrope with floating bed pull in to shore the side bolt on the bank slope at peak level place, and the offshore side of floating bed can the lifting with the fluctuation of water level.

2. according to the greening method of the said fluctuation in stage region shore slope of claim 1, it is characterized in that: connect with tightrope between the floating object of composition floating bed.

3. according to the greening method of the said fluctuation in stage region shore slope of claim 1, it is characterized in that: be fixed along the water (flow) direction floating bed.
