摘　　要：随着我国城市面积不断扩张,我国许多城市面临着水资源短缺、地下水储量不足、水质污染和内涝的问题.针对这些城市水环境问题,我国2015年提出"海绵城市"建设.本文以辽宁省盘锦市辽东湾新区为例,依据《海绵城市建设技术指南-低影响开发雨水系统构建(试行)》,通过对典型区进行下垫面及各地块用地类型分析,结合研究区地形、水文、降雨强度等因素,选取低影响开发(LID)措施对研究区海绵城市规划进行设计.结果表明:研究区达到整体目标控制率(年径流总量控制率大于75%)时,下沉式绿地率为1%~31%,下沉式绿地总面积达13.73 km^2;透水铺装率为1%~13%,透水铺装总面积达2.29 km^2.本研究能够为海绵城市规划设计提供案例,对景观格局与过程研究也提供了新的思路和方法.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 overall 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 kin2; the pervious pavement rate was 1%- 13%, with a total area of 2.29 km2. 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.
