The invention discloses a self-adaptive flood-drought mutual aid system and method for a river channel in an arid region based on terrain remodeling, and belongs to the technical field of ecological water conservancy projects. The system comprises a water and sediment separation topographic unit, a threshold value overflow topographic unit, a narrow and deep evaporation restraining topographic unit and an outer side beach overflowing flood area which are sequentially arranged in the water flow direction and coupled. A bottom plate of the water-sediment separation shape unit is provided with a transverse slope inclining towards an outer side concave bank, and bottom layer sediment is guided by gravity to be conveyed to the outer side; the narrow-deep evaporation-inhibiting terrain unit adopts a narrow-deep compound section with a large depth-to-width ratio to collect clear water so as to inhibit evaporation; and the top of the threshold overflow terrain unit forms a physical threshold for flood and drought switching. The invention further discloses a corresponding implementation method. According to the system, by remodeling the geometric shape of a riverbed, self-adaptive switching between clear water returning, efficient sand discharging and evaporation restraining in the dry season and muddy water beach overflowing, ecological supply and automatic dredging in the flood season is achieved, and the problems of water-sand contradiction and ecological water use of wandering rivers in the arid region are effectively solved.

The utility model discloses a water conservancy floodplain sector fine particle soil gravel reservoir seepage control body construction vibration roller compactor belongs to vibration roller compactor technical field for floodplain sector construction site use, including vibration roller compactor car body, the lower both sides of roller compaction wheel and be located in the back -to -back frame beam bottom is provided with dust removal subassembly, when the roller compaction wheel is on the fine particle soil gravel reservoir seepage control body construction site of floodplain sector and rolls, dust removal subassembly can synchronous removal roller compaction wheel roller compaction end before and after two sides' dust particle, the both sides of roller compaction wheel and be located in the back -to -back frame beam symmetry is provided with buffer limiting component, when roller compaction wheel rotates and executes roller compaction operation in back -to -back frame beam, two buffer limiting components can buffer and stroke limit to the vibration of roller compaction wheel. The utility model is dusted while compacting, can finish cleaning without interrupting operation, need not extra watering or manual cleaning, saves process time.

A layout of ecological spaces in river corridors is provided. The ecological spaces comprise water ecological spaces and land ecological spaces. The water ecological spaces comprise river channels, floodplains, and lakes and wetlands adjacent to and communicated with the river channels, and the land ecological spaces comprise forest and grasslands adjacent to the river channels, and strip-shaped ecological spaces along riverbanks, with a width of each of the strip-shaped ecological spaces meets ecological functional requirements by a corresponding river section. The layout of the ecological spaces in the river corridors follows a “patch-corridor-node” mode, and the ecological spaces in the river corridors are divided into water ecological patches, water ecological corridors, water ecological nodes, land ecological patches, land ecological corridors, and land ecological nodes.
