Zusammenfassung:	The invention discloses a river reach ecological positioning method and system, equipment and a medium. The river reach ecological positioning method comprises the steps of obtaining river reach ecological evaluation indexes; determining standards and weights of the river reach ecological evaluation indexes, and constructing a fuzzy evaluation index system to obtain a fuzzy evaluation result; determining an evaluation index set and a river reach ecological evaluation index membership degree; constructing a single-element evaluation fuzzy matrix, and obtaining an index fuzzy hierarchy comprehensive evaluation result; and based on the index fuzzy hierarchy comprehensive evaluation result and the fuzzy evaluation result of the fuzzy evaluation index system, obtaining a comprehensive evaluation result of river reach ecological positioning. The river reach ecological positioning system comprises an index acquisition module; a fuzzy evaluation module; a membership degree setting module; a fuzzy hierarchy evaluation
