| 气候环境研究具有多尺度层级的特征，城市气候环

表明，城市物理环境对气候改善具有决定性作用。以存量时代
城市更新改造为背景，从“多尺度”视角切入，重点关注城市
气候环境改善在不同尺度层级的途径与方法，共同指导城市更
新改造的具体操作。以北京市丰台区为研究对象，利用城市环
境气候地图分析城市片区内气候环境敏感性分级。首先，对建
成环境影响要素进行综合分析，结果显示，丰台区中部气候环
境敏感性高的区域，其建筑密度大、建筑高度高、植被覆盖率
低、路网密度高。其次，引入网格化分割降级气候环境分析尺
度，将敏感单元落在城市街区尺度内，研究得到丰台区5个气
候高敏感片区，其中4个为批发市场城市功能，具有典型性。
最后，针对典型敏感片区建成环境特征，总结街区改造策略，
提出多尺度气候环境分析的重要性，以及基于微气候改善的精
细化途径，这是存量时代城市应对气候环境变化的有效方案。 |

| Abstract: |
| Climate environment research has characteristics of multiscale and multi-level, so the improvement of urban climate environment
needs to focus on issues of different levels from different scales. Many
research results show that urban physical environment plays a decisive
role in climate improvement. Based on the background of urban
renewal and transformation in stock age, this paper focuses on ways
and methods of urban climate environment improvement at different
scales and levels, so as to guide specific operation of urban renewal
and transformation from perspective of "multi-scale". Based on Fengtai
District in Beijing, this paper uses urban climate map to analyze climate
environment sensitivity classification in the urban area, and the results of
comprehensive analysis of built environment factors show that the area
with high climate sensitivity in central Fengtai District has high building
density, high building height, low vegetation coverage and high road
network density. Secondly, the paper introduces grid segmentation to
degrade climate environment analysis scale, and focus sensitive unit on
urban block scale, and five climate sensitive areas in Fengtai District are
studied, four of which are typical urban functions of wholesale market.
Finally, according to the characteristics of built environment in typical
sensitive area, this paper summarizes block reconstruction strategy and
importance of multi-scale climate environmental analysis and refinement
approach based on microclimate improvement are proposed, which is an
effective solution for cities to cope with climate environmental change in
stock age. |
