摘要
“山—水—城”的滨水立面天际线对感知滨水城市魅力,彰显城市历史风景特色具有重要意义。该文以无锡蠡湖湾滨水区总体城市设计为研究对象,依托于GIS技术平台,以分形理论中的计盒维数法对城市天际线进行分段与分层提取,依此进行分形维数的计算与评估。通过多维度对比,从天际线轮廓线形状、平均转折点数、建筑高度的变化程度等多个方面进行城市天际线的量化评价及形态调控优化,为城市天际线定量评价的理论方法研究提供新的思路,为其他山水城市高度体系建构提供参考与建议。
The waterfront skyline of"mountain-water-city"is important for perceiving the charm of the waterfront city and highlighting the historical landscape characteristics of the city.Taking the overall urban design of Wuxi Lihu Bay waterfront as the research object,relying on the GIS technology platform,we extract the city skyline by segmentation and stratification with the box counting dimension method in the fractal theory,based on which the fractal dimension is calculated and evaluated.Through multi-dimensional comparison,the quantitative evaluation and morphological control optimization of the city skyline is carried out from various aspects such as the shape of the skyline contour line,the average number of turning points and the change degree of building height,which provides new ideas for theoretical methods of quantitative evaluation of the city skyline and provides references for the construction of other landscape city height systems.
