Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] like figure 1 As shown in , it is a schematic structural diagram of the vegetation restoration method in the water-fluctuation zone of the reservoir provided by this scheme.

[0027] The method for restoring vegetation in a water-fluctuating zone of a reservoir of the present invention comprises the following steps:

[0028] S1. In the dry season, excavate inward the bank soil at a set depth at the set position on the bank of the reservoir at an inclination angle of 30 degrees to the horizontal plane to obtain an inclined groove 1 at an inclination angle of 60 degrees to the horizontal plane. like figure 2 and Figure 4 shown.

[0029] Among them, the setting position is generally 10cm to 30cm above the lowest water level in the dry season to ensure the water source required for the growth of the lowest side plants in the inclined tank 1, and the depth is genera...

Abstract

The invention discloses a method for restoring vegetation in a water-level-fluctuating zone of a reservoir. The restoration method comprises the steps of: in the dry season, at a set position of a reservoir bank, inwardly dredging shore soil at a set depth along a dip angle of 30 degrees to a horizontal plane and obtaining an inclined trough with a dip angle of 60 degrees to the horizontal plane;digging a plurality of mounting grooves in the side surface, deviating from a water source, of the inclined trough along the set position; and prefabricating partition frames and stone cage columns, filling the partition frames with compacted composite soil, mounting the partition frames and the stone cage columns in the mounting grooves respectively, and forming a plurality of planting grooves among the partition frames, the stone cage columns and the side surface of the inclined trough respectively. The restoration method can solve the problem of a poor management effect on the water-level-fluctuating zone of the reservoir in the prior art, is high in efficiency, low in construction volume and high in success rate, and can ensure the survival of the vegetation at the same time.

Description

technical field [0001] The invention relates to the technical field of ecological control engineering, in particular to a method for restoring vegetation in a water-fluctuating zone of a reservoir. Background technique [0002] The ebb and flow zone refers to rivers, lakes, reservoirs and other water bodies that connect the water and land areas and are periodically submerged with seasonal and tidal fluctuations, forming alternating dry and wet mixed zones. Barriers and hydrofluctuation zones play a vital role in water body health and ecological security. [0003] Compared with water bodies such as inland rivers and lakes, the ebb and flow zone of the reservoir has the characteristics of low fluctuation frequency, but the water level difference between the dry season and the flood season is relatively large. As a result, the plants growing in the dry season are submerged in the flood season, which leads to the drowning of vegetation, which in turn leads to the destruction of...
