抄録

Environmental management should be implemented as part of a regular management even if an engineer in charge of a river site does not have special skills or long experience. The authors indicated the basic idea of the environmental management as "the relatively good site is conserved and other sites are restored referring the good site as much as possible", and proposed the river environment basic sheet to support to set the good site. In this study, the methods which set the good site from the typical and special aspects, and select a stretch to implement conservation and restoration as priority were examined. As a result, a procedure which sets a prioritized stretch to implement the measures from the similarity aspect was indicated in addition to the complementarity and non-substitutability aspect for the distance of two points in a river.
