Abstract: 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.

Abstract: A soil desalination and salt control apparatus and method for a bank of a lake reservoir are provided. The apparatus includes a soil washing system and an auxiliary heating evaporation system; the soil washing system includes a desalination fabric laid on a surface of soil in a to-be-desalinated area, a washing pipeline set on the desalination fabric, and a washing water source connected to the washing pipeline. Washing holes are provided on a lower end side of the washing pipeline towards the desalination fabric. The auxiliary heating evaporation system includes an auxiliary heating circulation pipeline buried inside the soil of the to-be-desalinated area, and a heat source assembly and an auxiliary heating control system both connected to the auxiliary heating circulation pipeline. The burial depth of the auxiliary heating circulation pipeline is the desalination control depth of soil of the bank of the lake reservoir.
