Method for constructing river bank stabilization-buffering-regulation function improving buffer zone
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.
本发明涉及构建河岸稳定‑缓冲‑调控功能提升缓冲带的方法。本发明公开了一种适宜于北方地区的，能够改善河岸侵蚀、有效阻控农业面源污染，同时调控抑制外来植物入侵，有效提升河岸带稳定‑缓冲‑调控功能的河岸缓冲带构建方法，属于生态及环境保护领域。本发明所述方法是针对生态功能退化的河岸带，特别是边坡侵蚀较重、河岸植被单一、外来植物入侵、农业面源污染影响大的河岸区域。分为边坡防护区和缓冲调控区。边坡防护区进行人工修整，自常水位区到缓冲调控区进行削坡，坡脚处采用石笼稳固，坡面上采用密植扦插与种植相结合的方式栽种杞柳。缓冲调控区由三部分组成：靠近岸坡处为紫穗槐与草地早熟禾调控带，中间为一条生态阻隔带，外侧为灌草阻控带。本发明适宜于受人为干扰大、存在严重外来植物入侵且水土流失较重的退化河岸带，可以起到防护河岸稳定、提升河岸植物多样性、减少面源污染的作用，同时还具有良好的经济及景观美学功能。
