Say goodbye to the rain but hello to the green: slopes with plants.

　　As the development of cities, green city, sponge city and ecological city have become the construction aim. There are 124 watercourses spread all over Ji’nan city, not only dressing up the whole city and nourishing Ji’nan people but also draining away water. Hardening method is normally used in the protection of slopes , like other demostic cities , in a bid to drain away water to avoid flood , but lack of green and ecology. Now in order to relieve urban waterlogging and recover urban ecology , river system project department in a sponge city has plant green plants on slopes and side slopes along the off-city rivercourse in the pilot region.
