| Research Abstract |
It was confirmed that ecosystem conservation facilities pose depression of canal ability and homogenization of material flow in canals, although it contribute largely to conserve biodiversity. Some methods were developed to measure transition of ecosystem. It became clear that to shovel dirt and to cut grass were heavy labor for farmers. Shoveling and cutting would be obstacles to introduce ecosystem conservation facilities to aging rural area. Inhabitation of small group that had genetic polymorphism locally was observed.
Requirement for construction of ecosystem conservation facilities are as follows.
1) To consider environmental elements, for example land use in upper reaches, that determine quantity of sediment is important.
2) It is necessary to examine combination of Semi-natural construction method and traditional method depending on the maintenance ability by humans.
3) To consider genetic characteristics may be needed for networking of canals.
