摘要
以常州市蔷薇湿地公园为例,提出一种"垂直流+水平流"新型生态补水复合模式,探讨了该模式的环境效应和经济效益.结果表明:该补水模式不但能净化受污染的源水(城市河水),而且可有效提升城市湿地公园的生态景观功能.城市湿地公园内的大部分景观水体可达到全身接触性娱乐类景观功能要求,运行成本仅为常规补水工艺的5～25,具有较好的环境效应和经济效益.
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.
