With the expansion of urban area, many cities are facing urban water environment issues, i.e., water resources shortage, lack of groundwater reserves, water pollution, urban waterlogging. For resolving these urban issues, 'sponge city' was proposed in 2015 in China. Liaodong Bay area of Panjin City in Liaoning Province of China was chosen as case study. Based on 'Sponge City Construction Technology Guide: Low Impact Development Rainwater System Building (Trial)', the underlying surface and types of land use in the typical area were analyzed. Sponge city plan of the study area was designed through combining topography, hydrology, rainfall intensity and other factors, and selecting LID measures. The results showed that when the study area reached the ove-rall target control rate (the control rate of the total annual runoff was ＞75%), the subsidence greenbelt rate was 1%-31%, with a total area of 13.73 km; the pervious pavement rate was 1%-13%, with a total area of 2.29 km. This study could provide a case study for planning and designing of 'sponge city', proposing new ideas and methods for the research on landscape pattern and process.
随着城市面积的扩大，许多城市面临着城市水环境问题，即水资源短缺、地下水资源储备不足、水污染、城市内涝。为解决这些城市问题，中国于2015年提出了“海绵城市”的概念。选取中国辽宁省盘锦市辽东湾地区作为案例研究。基于《海绵城市建设技术指南：低影响开发雨水系统构建（试行）》，对典型区域的下垫面和土地利用类型进行了分析。结合地形、水文、降雨强度等因素，选择低影响开发（LID）措施，设计了研究区域的海绵城市规划。结果表明，当研究区域达到总体目标控制率（年径流总量控制率＞75%）时，下沉式绿地率为1% - 31%，总面积为13.73平方千米；透水铺装率为1% - 13%，总面积为2.29平方千米。本研究可为“海绵城市”的规划设计提供案例参考，为景观格局与过程研究提出新思路和方法。
