Basin ecological corridor safety pattern construction layout method

The invention discloses a basin ecological corridor safety pattern construction layout method. The method comprises the following steps: S1, constructing an index system on a macroscopic level of a drainage basin ecological corridor based on an index factor of an ecological safety pattern partition, an ecological source index factor and a landscape resistance surface index factor; S2, on the basis of the relation among the river ecological process, the space structure and the service function, combining gallery construction and structure index elements, and constructing an index system on the mesoscopic level of the ecological gallery of the drainage basin; S3, identifying a landscape pattern based on spatial element analysis, partitioning an ecological pattern, and constructing an ecological safety pattern of a macroscopic level of the drainage basin according to connection of an ecological region, an ecological source land and an ecological corridor and ecological positioning; and S4, selecting an ecologica
