1. Fish Habitat Enhancement: (1)Heavy damages for fish habitat are often brought by simplification of streams such as channel straightening. (2) Critical components for fish habitat are shelters in swelling period, rearing places, spawning places and migrating routes. (3)In order to ensure shelters, deep pools and hollow places in side banks should be preserved or installed in channelizations. (4)Spawning places can be given or installed artificially after channelizations. (5)Fishways for upstream migrating and fish protect screens and bypasses for downstream migrating should be installed in every obstacles.2. Flood Protection: It is an urgent subject for habitat enhancement projects in Japan to develop a check system for flood protection and a simple method for three dimensional analysis of high water flows.3. Water Quality: Some devices can be installed for restoration of self- purification-function in streams. Preservation of aquatic plants and purification of input-water, however, are more important and effective for stream habitats.

1、鱼类栖息地的改善： (1)河道矫直等河道简化往往对鱼类栖息地造成严重破坏。 （2）鱼类栖息地的关键组成部分是盛期庇护所、饲养场所、产卵场所和洄游路线。 （3）为保证避难，渠道化中应保留或设置深水池和岸边空心处。 (4)产卵场所可在渠化后人工设置或设置。 （5）各障碍物处均应设置上游洄游鱼道和下游洄游鱼护网及旁路。 2．防洪：开发防洪检查系统和高水流三维分析的简单方法是日本栖息地改善项目的紧迫课题。 3．水质：可安装一些装置恢复溪流的自净功能。然而，水生植物的保护和输入水的净化对于溪流栖息地来说更为重要和有效。
