Evaluation of Sponged City Construction Level and Regional Governing Strategic Management
[Objective] To explore the effectiveness of sponge city construction and its key driving factors
in order to provide theoretical basis and policy guidance for sponge city construction in different areas in China. [Methods] The evaluation index system of sponge city construction was established from four aspects including water environment safety
the utilization of water resource
water pollution control and water habitat construction. According to the topography
climate and development scale
Beijing
Chongqing and Zhenjiang City were selected as the study areas. The change of sponge city construction and its key influencing factors was quantitatively analyzed by principal component analysis and fuzzy-gray comprehensive evaluation model. [Results] From 2006 to 2015
the index of sponge city construction showed an upward trend. Of all the sub-target layer construction indexes
only the water resources utilization index of Beijing and Chongqing City has decreased. [Conclusion] Chinese sponge city construction has achieved initial success
and urbanization is closely related to the change of sponge city construction index. The construction of sponge city in North China and East China should also strengthen the control of the reservoir volume per unit area and agricultural pollution load; and based on topographic analysis
the construction of sponge city in mountainous cities should also strengthen the control of water saving and domestic wastewater discharge.
