A site selection method and system for a river-crossing passage

Abstract

The application discloses a site selection method and system for a river-crossing passage, relates to the technical field of river-crossing passage layout, and comprises the following steps: acquiring multiple river-crossing passage site selection schemes; taking spatial connectivity, ecological sensitivity and a whole life cycle cost as evaluation indexes of the river-crossing passage site selection, and performing quantitative calculation on the evaluation indexes in the multiple river-crossing passage site selection schemes; obtaining evaluation values of the multiple river-crossing passage site selection schemes according to the quantitative calculation results of the evaluation indexes in the multiple river-crossing passage site selection schemes, and determining an optimal river-crossing passage site selection scheme through the evaluation values of the multiple river-crossing passage site selection schemes. The application breaks through the single-dimension analysis limitation of the prior art engineering orientation, realizes the coordinated consideration of the function, ecology and economy of the river-crossing passage site selection, effectively solves the problem that the traditional site selection does not consider the traffic network function and ecological constraints, and thus the scientificity and rationality of the site selection decision are remarkably improved, and the coordinated development of regional traffic network construction and ecological environment protection is promoted.
