[A new type water supplement mode of urban wetland park and its effects in purification and ecology].
With the Rosebush Wetland Park in Changzhou as a case, a new type water supplement mode for urban wetland park, i.e., "vertical-flow plus horizontal-flow", was constructed, and its effects in water purification, ecology, and economic advantages were evaluated. The results showed that this water supplement mode could not only improve the landscape of the water bodies in urban wetland park, but also enhance their quality, making it satisfy the requirement for human full-body exposure. Furthermore, the operation cost of the mode was as lower as 5%-25% of direct municipal pipe-water supply and other routine technique solutions, suggesting that this water supplement mode had potential positive ecological effects and economic advantages.
