Layout of Ecological Spaces in River Corridors and method for constructing same

A layout of ecological spaces in river corridors, wherein 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, wherein a width of each of the strip-shaped ecological spaces meets ecological functional requirements by a corresponding river section;

• wherein the layout of the ecological spaces in the river corridors follows a “patch-corridor-node” mode;
• wherein large lakes and wetlands communicated with the river channels serve as water ecological patches;
• wherein river sections and river channel areas that do not allow for building wide floodplains serve as water ecological corridors;
• wherein wide floodplains, river bends, and river channel areas and adjacent riverbanks that allow for being transformed into wide floodplains, river bends, small side-channel river wetlands, and lake pond wetlands, serve as water ecological nodes;
• wherein large patches of forest and grasslands adjacent to the river channels, and areas allow for building large patches of forest and grasslands, serve as land ecological patches;
• wherein forest and grassland belts along the river channels, and strip-shaped ecological spaces along the riverbanks that allow for building forest and grasslands, serve as land ecological corridors;
• wherein small patches of forest and grasslands distributed intermittently along the river channels, and ecological spaces along the riverbanks that allow for building small patches of forest and grasslands, serve as land ecological nodes.
