Research On Water System Planning From The Perspective Of Stormwater Management In Winter City

It's been widely proved and practiced for the planning theories of stormwater management,whose application is still in exploration for the winter city featured as complex climate and harsh environment,also for the sponge city and other theories.as the crucial component of ecological infrastructure,urban water system affords the responsibility of stormwater management.In winter cities,however,water system greatly differs from counter parts in other regions mainly in resource characteristics,functionality and spatial features,etc.In this paper,based on the theory of stormwater management,the author puts forward the framework of urban water system planning system to deal with the characteristics and key issues of urban water system.Three spatial scales are involved: watershed,city planning area and riparian buffer reach to explore the planning routes of urban water system in construction of regulation and control system of basin water system,adjustment of water system spatial pattern in winter city planning area and ecological construction of winter city riparian buffer.The urban water system is guided planning based on scales and importance to achieve sustainable construction and implementation of sustainable stormwater management.Water system in winter city is taken as the object in this paper.Firstly,the characteristics of water system in winter city are combed from the function,characteristics,constitution and relevant regulations and plans.The objects planned of urban water system are spatially divided into small watershed water system,water system of urban planning area and riparian buffer reach combined with the macro,medium and micro planning perspectives of urban and rural planning.Secondly,the stormwater management is defined to theoretically define and identify the principles of stormwater management application in winter cities.Ultimately,based on the above theories and self-examination of the present planning and construction of water system in winter city,the author provides the future planning construction with the development orientation following the integration of urban water and land resource with landscape planning,the pursuit of comprehensive water control in zoning treatment,technical realization of water system planning and guidance of planning and construction implementation with political adjustment.To further clear the new task of water system in winter city,the planning framework of water system is established based on the stormwater management.Depending on the functional and design principles constitution,the key points of water system planning are divided into three levels under the view of stormwater management from overall object coordination,multi-scale decomposition and special coordination.The ways and optimization strategies of sustainable stormwater management for urban water system are further analyzed from macro,medium and micro perspective.The results are to construct of regulation and control system of basin water system,adjust the water system spatial pattern in winter city planning area and ecological construct the winter city riparian buffer all based on the stormwater management.The exploration also extends to the cooperation methods in water projects,water environment and landscape planning to achieve the construction of stormwater management,taking the urban water system as the media.New task requires advanced planning methods,which presents the specific ways from macro,medium and micro levels.The specific strategies of watershed regulation system for macro-construction include water supply with snow and rainwater utilization,construction of ecological pattern,on-site reservation with zoning treatment and integration of water and land resource with landscape planning;the planning strategies of urban water system regional layout for the medium-adjustment can be divided into the optimization of land use layout along water system,the construction of management and control unit of Living with water area and the optimization of waterlogging disaster in evacuation sites;the macro-ecological construction and technical implementation of riparian buffer include the restoration of riverway naturalization,adjustment of structural layout of riparian buffer and constitution of water-ecological infrastructure.Finally,connotation of layered water system planning is taken into account to respectively construct the integrated river basin management,integrated space control of water system,security of planning and construction and guidance to contribute to the planning construction and healthy operation of urban water system.Based on multiple disciplines including water conservancy,water environment,landscape architecture,municipal engineering and water supply and drainage,this paper follows the urban planning and focuses on the design to figure out the ways of sustainable realization of stormwater management of water system in winter cities.The planning and construction elements of water system are determined to realize the stormwater management through layered construction,division of sub-systems and realization of multiple ways.The practice process of planning cases are decomposed to testify the theory and implementation of this methods through the combination of theories and practice.This paper lays down the scientific guidance and operation ways for the satisfaction of sustainable stormwater management with the water environment conservation and water system planning,also the reference for other water system planning projects in winter cities.
