| 摘 要： | 不透水率是衡量城市生态环境状况的一个重要指标。当前全球范围内仅有1 km和30 m分辨率尺度的不透水面专题信息，无法满足城市尺度水文模型建模、海绵城市规划和建设需求。提出了图谱信息融合的不透水面提取模型，实现了基于深度学习的不透水面提取新方法，研制了不透水面遥感全流程提取和监测软件。基于多源高分辨率遥感影像首次完成了中国31个省（直辖市、自治区）的2 m不透水面专题信息提取，形成全国不透水面一张图，为海绵城市和生态城市的建设提供了基础数据支撑和技术监测手段。

| Abstract: | Impervious rate is an important indicator to evaluate the urban ecological environment. Currently, there is only 1 km and 30 m resolution of impervious surface thematic information in the global scope, which cannot meet the needs of urban scale hydrological modeling, sponge city planning and construction. In this paper, an impervious surface extraction model incorporated spectral and texture information is proposed, and a new method based on deep learning is implemented to estimate imper-vious surface information. In addition the software for extracting and monitoring of impervious surface is also developed. Based on multi-source high spatial resolution imagery, impervious surface map with 2 m spatial resolution in mainland China including 31 provinces (municipalities, autonomous regions) is accomplished, just supports the high resolution data to research and monitor sponge and ecological cities. |
