In order to study the water logging risk in lakeshore urban caused by the blocking drainage effect (BDE) of Poyang Lake, the "regulation and storage model" was used to elucidate the BDE of Poyang Lake on inner river drainage in Changnan District and to explore the impact of Poyang Lake on waterlogging risk of lakeshore urban. By defining the Index of Blocking Drainage (IBD) which quantifies the BDE, the main controlling factors that affect the IBD was explored and the response relationship between them was quantified. The results show that the main controlling factors affecting the IBD include rainfall intensity, water level of outer river, drainage capacity and storage space. There is an obvious quadric curve relationship between rainfall intensity and the IBD, and 11.67 mm/h is the inflection point of the curve. There is a four-quadrant risk diagram relationship between the IBD and the water level of outer river. The decrease frequency of the IBD increases with the increase of drainage capacity. The effect of reducing the IBD by improving the drainage capacity of Changnan District is obviously reduced when the rainfall intensity exceeds 11.67 mm/h. The IBD of the same rain intensity decreases gradually with the increase of storage space. The effect of reducing the IBD of Qingshanhu District by increasing the storage space is obviously reduced when the rainfall intensity exceeds 15.83 mm/h. The water logging risk in lakeshore urban caused by the DBE of Poyang Lake can be effectively reduced by appropriately improving the drainage capacity, reducing the proportion of impervious ground and increasing the adjustable storage space, but the ability to deal with extreme rainstorm events remains limited.

为探究鄱阳湖阻排效应造成的滨湖城市内涝风险,采用“调蓄模型”阐明鄱阳湖对昌南城区内河外排的阻排效应,定义量化阻排效应的阻排系数,探明了影响阻排系数的主控要素并量化阻排系数与主控要素之间的响应关系。结果表明,影响阻排系数的主控因素包括降雨强度、外江水位、排涝能力和调蓄空间等。降雨强度与阻排系数之间存在明显二次曲线关系,雨强11.67 mm/h为曲线拐点;阻排系数与外江水位呈四象限风险图关系;排涝能力提升比例增加,阻排系数降低频率增大,雨强超过11.67 mm/h后,昌南城区通过提升排涝能力降低阻排系数的效果明显降低;调蓄空间增加,相同雨强的阻排系数逐渐减小,雨强超过15.83 mm/h后,青山湖排涝片通过提升调蓄空间降低阻排系数效果明显降低。通过适当提升排涝能力、降低不透水地面比例、增加可调蓄空间可有效降低鄱阳湖阻排效应造成的滨湖城市内涝风险,但应对极端暴雨事件的能力仍然有限。

为探究鄱阳湖阻排效应造成的滨湖城市内涝风险,采用“调蓄模型”阐明鄱阳湖对昌南城区内河外排的阻排效应,定义量化阻排效应的阻排系数,探明了影响阻排系数的主控要素并量化阻排系数与主控要素之间的响应关系。结果表明,影响阻排系数的主控因素包括降雨强度、外江水位、排涝能力和调蓄空间等。降雨强度与阻排系数之间存在明显二次曲线关系,雨强11.67 mm/h为曲线拐点;阻排系数与外江水位呈四象限风险图关系;排涝能力提升比例增加,阻排系数降低频率增大,雨强超过11.67 mm/h后,昌南城区通过提升排涝能力降低阻排系数的效果明显降低;调蓄空间增加,相同雨强的阻排系数逐渐减小,雨强超过15.83 mm/h后,青山湖排涝片通过提升调蓄空间降低阻排系数效果明显降低。通过适当提升排涝能力、降低不透水地面比例、增加可调蓄空间可有效降低鄱阳湖阻排效应造成的滨湖城市内涝风险,但应对极端暴雨事件的能力仍然有限。

In order to study the water logging risk in lakeshore urban caused by the blocking drainage effect (BDE) of Poyang Lake, the "regulation and storage model" was used to elucidate the BDE of Poyang Lake on inner river drainage in Changnan District and to explore the impact of Poyang Lake on waterlogging risk of lakeshore urban. By defining the Index of Blocking Drainage (IBD) which quantifies the BDE, the main controlling factors that affect the IBD was explored and the response relationship between them was quantified. The results show that the main controlling factors affecting the IBD include rainfall intensity, water level of outer river, drainage capacity and storage space. There is an obvious quadric curve relationship between rainfall intensity and the IBD, and 11.67 mm/h is the inflection point of the curve. There is a four-quadrant risk diagram relationship between the IBD and the water level of outer river. The decrease frequency of the IBD increases with the increase of drainage capacity. The effect of reducing the IBD by improving the drainage capacity of Changnan District is obviously reduced when the rainfall intensity exceeds 11.67 mm/h. The IBD of the same rain intensity decreases gradually with the increase of storage space. The effect of reducing the IBD of Qingshanhu District by increasing the storage space is obviously reduced when the rainfall intensity exceeds 15.83 mm/h. The water logging risk in lakeshore urban caused by the DBE of Poyang Lake can be effectively reduced by appropriately improving the drainage capacity, reducing the proportion of impervious ground and increasing the adjustable storage space, but the ability to deal with extreme rainstorm events remains limited.
