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.
