系统化全域建设背景下平原河网地区海绵城市监测体系构建

Construction of Sponge City Monitoring System in Plain Rivernet Area under the Background of Systematic Global Construction

在系统化全域海绵城市建设背景下,为支撑平原河网地区海绵城市建设成效评价,应建立以典型片区为核心的系统化全域监测体系。针对平原河网地区排水系统特征与海绵城市监测难点,研究了根据空间布局、下垫面特征、地形、水系特征、海绵城市建设情况等因素确定典型片区数量、位置、边界等关键信息的方法,提出了片区内“本底特征、源头减排、过程控制和系统治理”系统化监测体系的构建方法。以宿迁市为例,介绍了海绵城市建设概况、典型片区选取方案与依据,并制定了2个典型片区系统化监测体系的构建方案,该方案有效支撑了宿迁市各层级海绵城市建设成效评价。

In the context of systematic and global sponge city construction,in order to support the evaluation of the effectiveness of sponge city construction in plain river network areas,a systematic and comprehensive monitoring system with typical areas as the core should be established.A method for determining key information such as the number,location,and boundaries of typical areas based on factors such as spatial layout,underlying surface characteristics,terrain,water system characteristics,and sponge city construction was studied in response to the characteristics of drainage systems in plain river network areas and difficulties in monitoring sponge cities.A systematic monitoring system for"background characteristics,source emission reduction,process control,and systematic governance"within the area was proposed.Taking Suqian City as an example,this paper introduced the overview of sponge city construction,the selection plan and basis of typical areas,and formulates the construction plan of two systematic monitoring systems for typical areas.This plan effectively supports the evaluation of the effectiveness of sponge city construction at all levels in Suqian City.
