Embodiment 1

[0023] This embodiment 1 is implemented under the following conditions of implementation and technical requirements:

[0024] A 35-meter-wide riverside vegetation buffer zone is constructed in the section of the Liaohe River Protection Zone at Shuang'an Bridge in Tieling City, which is divided into two parts: the slope protection zone and the buffer control zone.

[0025] The side slope protection area is manually repaired first, and the heavily eroded side slope is cut from the normal water level. The slope is set to 30°, and the foot of the slope is stabilized with gabions. . Starting from the gabion on the slope, a 2-3m willow wood pile is nailed every 50cm, and the willow willow is planted between the two piles by a combination of close-planting cuttings and planting. The cutting density of willow branches is 30 branches / m 2 , the annual planting density of willow seedlings was 0.5 m between plants and 0.5 m between rows.

[0026] Two rows of willow willows were planted...

Embodiment 2

[0034] This embodiment 2 is implemented under the following conditions of implementation and technical requirements:

[0035] A 50-meter-wide riparian vegetation buffer zone is constructed at the main stream section of the Liaohe River at the mouth of the Liuhe River in Xinmin City, which is divided into two parts: the slope protection area and the buffer control area.

[0036] The slope protection area is manually repaired first, and the severely eroded slope is cut from the normal water level, with a slope of 45°. The foot of the slope is stabilized with gabions, and willow bundles wrapped in non-woven fabrics are laid under the gabions. On the slope upwards from the gabion, a 2-3m willow wood stake is nailed every 50cm, and the willow willow is planted between the two stakes by means of close-planting cuttings and planting alternately. The cutting density of willow branches is 35 branches / m 2 , the annual planting density of willow seedlings was 0.5 m between plants and 0....

Abstract

The invention relates to a method for constructing a river bank stabilization-buffering-regulation function improving buffer zone, discloses a river bank buffer zone construction method which is suitable for northern areas, can improve river bank erosion, effectively prevents and controls agricultural non-point source pollution, regulates and inhibits alien plant invasion and effectively improves river bank zone stabilization-buffering-regulation functions, and belongs to the field of ecology and environmental protection. The method is used for river bank zones with degraded ecological functions, especially river bank areas with heavy side slope erosion, single river bank vegetation, alien plant invasion and large agricultural non-point source pollution influence. The buffer zone is divided into a side slope protection area and a buffering regulation area. The side slope protection area is manually trimmed, slope cutting is carried out from a normal water level area to the buffering regulation area, the slope toe is stabilized by adopting a gabion, and salix integra is planted on the slope surface in a close planting cuttage and planting combined mode. The buffering regulation area is composed of three parts, namely, an amorpha fruticosa and meadow bluegrass regulation zone close to the bank slope, an ecological barrier zone in the middle and a grass irrigation barrier control zone on the outer side. The method is suitable for degraded river bank zones which are greatly interfered by people, have serious alien plant invasion and are heavy in water and soil loss, can play roles in protecting river banks, improving river bank plant diversity and reducing non-point source pollution, and has good economic landscape and aesthetic functions.

Description

technical field [0001] The invention belongs to the field of ecology and environmental protection. Specifically, it is a method for constructing a riparian buffer zone that can improve the stability and buffer capacity of the riparian zone and regulate the alien invasive plants in the riparian zone. Background technique [0002] The riparian buffer zone is an ecological transition zone between river ecosystems and terrestrial ecosystems, with obvious edge effects and high biodiversity. The special geographical location determines that it plays an important role in preventing and controlling non-point source pollution, intercepting and stagnating sewage, maintaining biodiversity and creating riverside landscapes. As the main body of the riparian buffer zone, the riparian plant community plays a decisive role in protecting the riparian banks and preventing and controlling agricultural non-point source pollution. However, due to the impact of human activities, the damage and ...
