大理市下关城区建筑高度控制规划研究*

大理是国家历史文化名城、云南旅游度假胜地,下关是大理旅游集散服务基地,苍山环绕,洱海映衬,具有优质的外部空间环境,塑造具有高原山水特征的城市形象对下关城区至关重要.城市建筑高度是影响下关城区风貌特色的关键因子之一,基于现状调研及分析,本研究首先总结下关城区现状城市建筑高度的基本特征,其次广泛吸收借鉴国内外有关城市建筑高度控制方法研究,尤其是针对自然山水资源丰富、历史文化厚重的地区,提炼出“基准模型＋修正模型”高度控制框架,通过GIS多因子叠加技术和CAD视线剖断面分析技术,最后将该方法体系应用于下关城区建筑高度生成过程中,生成建筑高度控制引导表及控制分区图,为下一步控制性详细规划制定建筑高度指标提供参考意义.

A Study on Planning Control Building Height of Xiaguan District in Dali City

Dali is a national historical and cultural city, Yunnan tourist resort. Xiaguan district is the Dali tourism distribution service base, surrounded by hills, against the background of Erhai Lake, with a high quality external space environment. To shape the landscape of the city＇s image with the plateau is crucial. The city building height of Xiaguan district is one of the key factors to city style featuring. Based on research and analysis of current situation, this study firstly summarizes status basic characteristics of urban building height of Xiaguan district, secondly widely learns from the research on control method about urban building height, especially for rich natural landscape, heavy history and culture region, refines the ＂basic model plus correction model＂ for height control technology framework. Finally, by GIS technology and CAD overlay multi-factor cross sectional analysis techniques, the methodology is applied to build process of building height, for generating building height control guidance sheets and control zoning map to provide reference to the building height control for detailed planning.
