Problems solved by technology

The above-mentioned schemes all need to change the internal structure and soil environment of the original soil layer of the riparian buffer zone, thereby destroying the microbial community structure in the soil. For the riparian buffer zone, microorganisms are one of the main groups that decompose or degrade pollutants First, the damage to the structure of the riparian zone will break the balance of the microbial community, which will affect the decontamination effect
Therefore, the existing riparian buffer zone construction measures are not only not conducive to the removal of pollutants, but will also cause damage to the riparian ecosystem in severe cases.

Embodiment 1

[0031] Follow the steps below to construct a riparian ecological buffer zone:

[0032] (1) Delineate the construction area: select the river bank land area within 15 meters from the extension of the highest water level of the river as the construction area of ​​the river bank ecological buffer zone;

[0033] (2) Adjust the surface slope of the construction area to 7-8 degrees without changing the internal environment of the soil layer in the construction area;

[0034] (3) Determine the community construction scheme: in the construction area, a reed-grass belt with a width of 1.2 meters, a tree-shrub-grass belt with a width of 7 meters, and a shrub-grass belt with a width of 5 meters are arranged successively from near to far from the river. On the edge of the area far away from the river, dig a catchment ditch with a width of 1m at the bottom of the ditch, a width of 2m at the top of the ditch, and a depth of 1m along the direction of the river, and the rest is grassland;

Embodiment 2

[0044] Follow the steps below to construct a riparian ecological buffer zone:

[0045] (1) Designate the construction area: select the river bank land area within 20 meters from the extension of the highest water level of the river as the construction area of ​​the river bank ecological buffer zone;

[0046] (2) Adjusting the surface slope of the construction area to 5-6 degrees without changing the internal environment of the soil layer in the construction area;

[0047] (3) Determine the community construction scheme: in the construction area, a reed-grass belt with a width of 2 meters, a tree-shrub-grass belt with a width of 8 meters, and a shrub-grass belt with a width of 5 meters are set in sequence from near to far from the river. On the edge of one side of the river along the direction of the river, a catchment ditch with a width of 0.5m at the bottom of the ditch, a width of 1.5m at the top of the ditch and a depth of 0.5m is set up, and the rest is a grassland area; ...

Embodiment 3

[0056] Follow the steps below to construct a riparian ecological buffer zone:

[0057] (1) Delineate the construction area: select the land area of ​​the river bank within 50 meters from the extension of the highest water level of the river as the construction area of ​​the ecological buffer zone of the river bank;

[0058] (2) Adjusting the surface slope of the construction area to be 9-10 degrees without changing the internal environment of the soil layer in the construction area;

[0059] (3) Determine the community construction scheme: in the construction area, a reed-grass belt with a width of 2.5 meters, a tree-shrub-grass belt with a width of 25 meters, and a shrub-grass belt with a width of 17.5 meters are set in sequence from near to far from the river. On the edge of one side of the river along the direction of the river, a catchment ditch with a width of 1.5m at the bottom, a width of 2.5m at the top and a depth of 1.5m is set up, and the rest is grassland;

Abstract

The invention relates to a riverbank ecological buffering band and a construction method for the same. The construction method comprises the following steps of (1) selecting a construction area, (2) adjusting gradient of the construction area, (3) determining a group construction scheme, and (4) planting plants according to the group construction scheme. The invention further provides a riverbank ecological buffering band constructed according to the method. Plants are optimized without a change of an original soil layer structure of the riverbank buffering band, and sewage can be stopped and controlled before entering the river way; resistance of the sewage is increased when the sewage flows through the buffering band, working time of the sewage between the buffering band and plant roots and the soil micro-bial community can be increased; pollutants can be removed; water and soil loss can be reduced; load of pollutants flowing into the river can be reduced; and land resources can be conserved and environment can be beautified.

Description

technical field [0001] The invention relates to the field of environmental governance, in particular to a river bank ecological buffer zone and a construction method thereof. Background technique [0002] In our country, the rivers in many areas are artificially excavated, and tidal flats are formed around them. Sewage containing a large amount of pollutants enters the rivers and destroys the river ecosystem. Moreover, the salinization of soil in such areas is high, bank protection measures lead to a large amount of hardening of river bank soil, and few green plants can adapt to this harsh habitat condition, so that the vegetation types currently constructed for river bank management are relatively monotonous. The ecological landscape and water purification ability are not strong. [0003] In the prior art, herbaceous plants are mostly used in the treatment of rivers and coasts, and most of them are repaired in water bodies; however, because the pollutants in the river flow...
