Study on Key Technology of Ecological Water System Planning of Kaifeng City

摘要

The ecological water system of Kaifeng City is an integrated infrastructure of urban water conservancy with integrated functions such as flood control,drainage,water supply,water quality protection,hydrophilic landscape,water ecology and etc.In order to improve the technological level of ecological water system planning,the paper studies on the key technologies in allusion to planning ideas,network layout,water resources allocation mode,water ecology protection,operation protection measures and etc.In the study,the water system planning idea with integrated water,landscape and city is provided by combining with the characteristics of Kaifeng City,a growth type network layout of water system is developed,a multi-level and three-dimensional dynamic equilibrium configuration mode of water resource is formulated,a water ecology protection framework with combined point,line and face is constructed,and a complete winter operation security measure system of artificial wetland,which had successfully applied for a national utility model patent.The achievements of the study provide strong technical support for the ecological water system planning of Kaifeng City,and also provide a useful experience for the efficient,ecological and harmonious formulation of urban water system planning in surrounding similar cities.
