Sustainable development Build characteristic ecological hydrosphere 诊治内涝 在雨水汛期吸在干旱时期吐
Make a diagnosis and give treatment waterlogging In the rain season in dry period 随着城市的发展，城市内涝、道路行洪等城市病越发显著，成为大中城市的一大顽疾问题。在济南也不例外，每当雨季遭遇强降雨时，也不乏“雨后看海”的窘境。出现这样的情况与济南的地势条件有关。由于南北地势高差变化极大，局地暴雨突发性强、时间集中等因素影响，济南易产生道路行洪、内涝问题。虽然南部山区大量强渗漏带帮助实现部分雨水就地消纳，但硬化道路却加剧了城市排水难题，让雨水成为内涝包袱。通过建设海绵城市，将城市河流、湖泊和地下水系统的污染防治与生态修复结合起来，让城市变身海绵体，像它一样下大雨时吸水、蓄水、渗水，干旱时就把吸收的水吐出来，防止出现城市内涝。
Along with the development of city, the city disease such as urban waterlogging, road flood discharge all the more remarkable, become a big problem in large and medium-sized cities.In jinan is not exceptional also, whenever there is heavy rain during the rainy season, there are “after the rain to see the sea”.Appear such circumstance is aociated with the terrain condition of jinan.Due to the height of terrain changes greatly, local heavy rains sudden strong, the time to focus on factors, such as the problem of flood discharge and waterlogging in jinan are prone to.Although the southern mountains with a lot of strong leakage help realize part of rainwater in situ given, but intensified urban drainage problem, hardening roads make rain waterlogging.By building the sponge city, the city, rivers, lakes, and groundwater system of pollution control and ecological restoration, let the city turns into a sponge, like it when the heavy rain water absorption, water storage, water seepage, drought will vomit to absorb water, prevent urban waterlogging.雨水资源化 小投资实现高收益
Rainwater utilization Small investment to realize high yield 除了缓解城市内涝、减缓道路行洪问题，济南建设海绵城市，更在于解决济南如何保泉、水资源短缺、生态涵养的问题，从而构建生态、可持续的特色水圈，确保泉城之水永续“涌动”，确保城市生命永久延续。
In addition to alleviate the problem of flood discharge in urban waterlogging, slow, construction of jinan city sponge, more is to solve how to protect the spring, the problem of water shortage and ecological cultivation, so as to build the ecological and sustainable features hydrosphere, ensure the springs of water sustainable “surge”, to ensure permanent city life.在济南，城市建设区大部分为老城区，存在问题多、改造难度大。由于海绵城市重视对水体的保护，仅需要结合既有绿地、园林、水体增建调蓄设施，就能大大降低水污染治理费用及内涝造成的巨额损失，实现用相对少的投资达到更高的效益。据了解，济南降雨特点中峰值靠前，结合分布广泛的河道截蓄设施、片区蓄水池等能够有效地延缓峰值时间，降低峰值流速。通过控制雨水总量，还能达到降低径流雨水污染的目的。同时，济南市既有和规划中绿地面积及道路面积较大，绿化和道路浇洒用水需求大，该部分用水可以由集蓄的雨水代替，因此雨水可利用价值高。
In jinan, most of these areas for the old city, there is a problem, the transformation is difficult.Due to the sponge city attaches great importance to the protection of the water, only needs to combine both green space, landscape, water, additional storage facilities, can significantly reduce water pollution governance costs and waterlogging caused huge loes, implemented with relatively little investment to achieve higher efficiency.Learned, jinan rainfall characteristics of peak, combined with the distribution of a wide range of channel cro-section facilities, storage area reservoir can effectively delay the peak time, reduce the peak flow velocity.By controlling the amount of rain, but also can achieve the purpose of reduce the pollution of runoff.Both at the same time, jinan and planning of green land area and road area is larger, greening and road labor demand is big, the part of the water can be replace by accumulation of rainwater, so the rain high use value.以建设海绵城市为契机，济南市将进一步将这一理念贯彻到城市建设中，在用地控制、建设程序、指标体系方面以及规划、设计、建设实施、维护管理环节上，实行全方位、全过程的监管，把海绵城市建设的控制性要求纳入土地“两证一书”、“土地招拍挂”、施工图审查、开工许可、竣工验收等管控环节。尤其是“渗、滞、蓄、净、用、排”多措并举，采取源头治理，将雨水就地留存，减轻城市防洪压力，恢复生态涵养，实现雨水资源化，缓解水资源不足的压力，为济南建设常年喷涌的泉域以及市民饮用优质地下水等惠民工程发挥积极作用。
In urban construction sponge as an opportunity to jinan will further will carry through the idea of urban construction, in the aspect of land use control, construction procedure, index system and implementation planning, design, construction, maintenance and management proce, implement omni-directional, the whole proce of supervision, the inclusion of the control requirement of sponge urban construction land “two certificate book”, “land bidding auction,” to start construction, construction drawing review, approval, completion inspection and acceptance of control link.Especially “permeability, hysteresis, storage, net, with,” many measures simultaneously, taking source management, will rain on the left, reduce the preure of city flood control, restore ecological conservation, realize the rainwater utilization, to ease the preure from shortage of water resources, for the construction of jinan perennial gushing fountain domain and public drinking groundwater quality such as huimin engineering play a positive role.
