The invention relates to a water source water quality purification system for recovery of a natural bank zone of a river in an arid region, the water source water quality purification system comprises a hydraulic power supply unit, a water quality purification unit and a river bank remodeling unit which are sequentially connected in series, and water flow sequentially flows through the hydraulic power supply unit, the water quality purification unit and the river bank remodeling unit and then flows to an external river channel from the river bank remodeling unit; the hydraulic power supply unit comprises a sewage treatment plant and a water pumping station, the water quality purification unit comprises a soil percolation system and an ecological purification pond, the river bank remodeling unit comprises a floodplain, the floodplain is close to a river channel, and the floodplain is located between the water quality purification unit and the river channel; all structures in the water source water quality purification system are connected through a water diversion channel, and the water diversion channel between a water quality purification unit and a river channel penetrates through a flood plain. The soil percolation system comprises a multi-soil-layer percolation mechanism, at least one or more water distribution pipes are arranged in the multi-soil-layer percolation mechanism, and each water distribution pipe is correspondingly connected with a plurality of water quality strengthening and purifying grids.

The utility model relates to a dry stream type water flow channel suitable for a rainwater regulation and storage wetland purification system, which is characterized in that an upstream water body is communicated with a downstream water body by adopting a dry stream, and a first water distribution gabion wall used as a water inlet overflow weir is transversely arranged at the communicated part of the dry stream and the upstream water body; a second water distribution gabion wall used as a water making overflow weir is transversely arranged at the position where the first water distribution gabion wall is communicated with the downstream water body, and the first water distribution gabion wall and the second water distribution gabion wall are each provided with a low-position water passing channel. The water distribution gabion wall has a good rainwater retention effect in the process of transferring incoming water of an upstream water body to a downstream water body, pollutants in the water can be effectively filtered and diluted, the water quality is purified, the incoming water and outgoing water can be filtered and purified through the water permeation function of the water distribution gabion wall, and the water distribution gabion wall can be used for filtering and purifying water. And incoming water and outgoing water can quickly pass through when the incoming water quantity is too large, so that overflow caused by retention in upstream water and stream is avoided.

The utility model relates to the technical field of slope greening protection, and disclose a kind of slope greening protection structure, including slope, and protection assembly and irrigation subassembly are arranged on the slope upper side;Irrigation subassembly is located above protection assembly, and the protection assembly includes the first galvanized iron wire, second galvanized iron wire, third galvanized iron wire and fourth galvanized iron wire located above slope.The grid structure formed by the first galvanized iron wire, second galvanized iron wire, third galvanized iron wire and fourth galvanized iron wire reduces the slope maintenance requirement due to wind and rain erosion, and the fixing mode of pressing plate and ground nail, effectively enhances the stability of slope, prevents rock collapse and slope instability, and the use of planting bag makes vegetation recovery more direct and efficient, and the substrate ratio garden soil in planting bag provides a good soil environment for vegetation growth, so as to not only realize the stability of slope, but also improve the ecological and landscape value of slope through the planting of vegetation.

The application discloses a kind of modular ecological floating island water purification device, including floating island module and the shock-absorbing component assembled to its periphery.Floating island module is composed of installation base and bottom float, and multiple modules are flexibly spliced by shock-absorbing component, to improve overall wind and wave resistance.The device integrates energy-harvesting component, transmission component and water purification component, and the energy-harvesting component converts wave energy into mechanical energy through floating ball and guide rod, and unidirectionally transmits to the water purification component through the ratchet mechanism of transmission component.The water purification component includes a sewage collection basin, a water pumping cylinder and a sewage collection cylinder, and the water pumping piston performs water pumping operation under the drive of reciprocating screw rod, and cooperates with isolation disc and check valve to realize water lifting;Sewage cleaning component A and sewage cleaning component B automatically clean filter cone disc and filter disc respectively to prevent clogging.The application has the characteristics of stable structure, energy self-sufficiency and efficient purification, and the modular design is convenient for expansion, suitable for ecological restoration and pollution control of various water bodies.

The application provides a kind of water level fluctuation river beach zone degraded wetland Juncus effusus community directional recovery method, belongs to wetland water environment ecological management and landscape restoration technical field.The application includes the following steps: (1) the hydrological condition of river beach zone degraded wetland is investigated, and the target recovery area and the transplanting height and time of Juncus effusus are determined: the transplanting height of low-lying area is greater than or equal to 30 cm, and the transplanting is carried out in early May; the transplanting height of water level change area is greater than or equal to 25 cm, and the transplanting is carried out in early May; the transplanting height of humid area is greater than or equal to 20 cm, and the transplanting is carried out in mid-late May; (2) the degradation degree of Juncus effusus in the target recovery area is investigated, and the transplanting density of Juncus effusus is determined: the natural recovery is carried out in slight degradation area, 20-30 plants / m 2 are transplanted in moderate degradation area, and 40-60 plants / m 2 are transplanted in severe degradation area.The application can not only improve the growth adaptability of Juncus effusus, but also enhance the ecological function of wetland, and provide a new solution for ecological protection and sustainable development.
