西川河水由南向北穿过冈山市中心。绿道公园是在沿河流域2.4公里的地段内,设置了水上凉亭、格架墙、喷水、池沼、瀑布等,庭院式空间曲线地延伸至城市中。这项工程分三期实施,最后使冈山市荣获第一届“绿化都市奖”的建设大臣奖。西川河水是1601-1614年间冈山城筑城时,为划分城下町和田园区而开发的。起初做为饮水和生活用水,后来建设了新的供水系统,河水只用于灌溉,沿河设置了洗场(洗、刷食具的场所)并作为捕鱼、 The Nishikawa River flows through the center of Okayama from south to north. In Green Road Park, a water pavilion, lattice walls, water jets, pond marshes, waterfalls, etc. are set in a 2.4-kilometer section along the river basin. The courtyard-style space extends curvingly into the city. The project was implemented in three phases, and in the end, Okayama City won the first Minister of the Ministry of Construction for the “Green City Award”. The Nishikawa River was developed during the period of 1601-1614 when Okayama Castle was built to divide the castle town and the pastoral area. Initially used as drinking water and domestic water, a new water supply system was subsequently constructed. The river water was used only for irrigation, and a wash field (a place for washing and brushing utensils) was set up along the river and used as fishing.
