Modaobuwukanchaigong. Jiaxing City, Zhejiang Province, the construction of sponge city pilot in the preliminary planning and design stage, resistance to temper practicing slow action results, fully illustrated this point. Prior to the same batch of pilot cities in the country, the progress of the project in the construction of Jiaxing, there are 99 projects started construction, approval and other work, accounting for 85% of the total number of planned projects. Moreover, the construction of the city's sponge city not only to eliminate the "every man from the snow" like "for the sponge and sponge", but also "tube"".

First of all, it is in the development of the concept of the construction of the sponge City, the tube is wide, from the concept of urban development to the overall strategy of national ecological civilization construction. In Jiaxing city planning and Construction Management Committee of the Party committee, director of municipal garden Bureau Xiao Jianguo view, sponge city is not simply that out of the building, but not for the construction of city and the "sponge sponge". "In fact, the construction of the sponge city is the protection and restoration of the natural environment, while the impact of urban development on the environment to a minimum, but also from the overall consideration of the national ecological civilization construction. Moreover, the construction of the sponge city is not a panacea, it alone can not solve all the problems in the process of urban development, the key is to find suitable conditions for their own characteristics of the green development of the road." In this regard, the Chinese Academy of urban planning and Design Institute of water and vice president Xie Yingxia, vice president of engineering. She said, from the construction of ecological civilization, "landscape forest lake" to understand the breadth of the sponge city construction should not be one-sided, superficial that the sponge is building a city "dressing up", "stunning", to spread some permeable brick, built several cisterns, built a few blocks downgoinggrassland equivalent sponge City construction.

Reporters in Jiaxing to feel obviously during the interview, the cognitive concept, not only the sponge city construction technical team, the leadership of the competent authorities, and the city decision-makers have, more importantly, also for a more thorough understanding. In the opinion of Lu Jun of secretary of municipal Party committee, city construction sponge is designed to make the city become able to breathe, natural breathing, become "landscape forest lake" one of the "community of life". According to the characteristics of water environment in Jiaxing and the poor, water ecological deterioration, local area waterlogging risk factors, the most important task is to restore the ecology, reproduce the Jiangnan characteristics, make Jiaxing become a "clear and coastal green, fish, camellia garden city. "From a technical perspective, the city construction should follow the" sponge comprehensive permeability, hysteresis, storage, net, row, "six character principle, but because Jiaxing is water shortage city, soil permeability, high underground water level, it should be focused on the issue of" net ", focusing on reducing storm on water environment pollution".

Secondly, it is in the sponge city construction project management". Sponge city construction in Jiaxing, not only to declare the pilot sponge city construction projects, but for all construction projects with "water" related to the overall planning, with a total of five water treatment, the transformation of the old district, city infrastructure construction, water diversion project, outside the city renewal initiatives to promote synergy. This practice before the day after the newspaper reported, has aroused widespread concern in the industry. Although the office of the State Council issued the "guidance" on promoting the city construction of the sponge made it clear to co-ordinate the orderly construction, but as of now, this really requires the pilot city to implement is not much. Industry experts said: "this will not only spend more time and energy, and even affect the stage of the Ministry of housing and urban construction and other three ministries of the performance evaluation, but also increase the cost of investment, in the current local fiscal" pressure Alexander ', really will be balanced to executive level, need a lot of determination."

Finally, the construction of the project quality management system in the sponge City, the tube was wide, and the tube was far". According to the Jiaxing City Planning Institute of sponge (evaluation) center director Wang Xianping introduced, in compliance with the technical standards for the city construction projects to protect the sponge, Jiaxing issued a "Jiaxing City sponge demonstration area construction engineering design scheme evaluation method", "Jiaxing City sponge demonstration zone construction drawing design documents review" and "Jiaxing sponge city demonstration area construction project completion measurement evaluation method" 3 ways, from planning, design, construction and acceptance of the whole process to strengthen the project quality control. At the same time, in order to make these measures implemented, will also develop "Jiaxing city low impact development facilities", "Jiaxing city standard atlas of low impact development facilities construction, inspection, maintenance, technical regulations" "Jiaxing city demonstration zone sponge monitoring program" and "Jiaxing urban rainwater control management measures", "sponge city maintenance management methods", "city of blue line management measures" and a set of scientific technical standards and management system, to provide technical support and guarantee the full range of sponge city pilot construction.

Up to now, has completed the construction of demonstration area of city planning, water planning, green space system planning, traffic planning and other planning and the "Jiaxing city low impact development facilities", "Jiaxing city standard atlas of low impact development facilities construction, inspection, maintenance, technical regulations" "Jiaxing city demonstration zone sponge monitoring program" etc. a series of technical standards for "Jiaxing urban rainwater control management measures", "sponge city maintenance management measures", "city of blue line management approach" has begun to develop.
