3D GIS空间视觉特征量化分析——以泉州大厝为例

Research of Spatial Visual Features of Quanzhou Dacuo HousesBased on 3D GIS

空间视觉关系的具身性、空间维度关系的复杂性、空间数量关系的难测度性和空间感知关系的难度量性是影响空间研究深入的主要因素。基于3D GIS空间技术,采用三维空间可视域、空间占比及太阳阴影分析因子分析了大厝空间视觉特征,为空间视觉特征量化研究方法更新提供了新视角。空间实验表明:小体量大厝整体可视域呈现两个峰值,中、大形体量大厝整体可视域变化加大;大厝深井空间体积分布以递增的形式发展,空间整体体量越小,深井空间占比越大;大厝建筑形制充分考虑了其受到建筑整体朝向的影响,并做到了有效的规避。

The main factors that affect spatial research are the embodiment of spatial visual,the complexity of spatial dimension,the difficulty of measuring the spatial quantity and of measuring the spatial perception.Based on the 3D GIS spatial technology,the spatial visual features of the Quanzhou residential houses are analyzed by using 3D spatial viewable area,spatial proportion and shadow analysis factors,which provides a new perspective for the updating of quantitative research methods of spatial visual features.The space experiment shows that the overall visual field of the small volume and the large volume shows two peaks,and the change of the overall visual area of the medium and large houses increases;the spatial volume distribution in Quanzhou Residential houses with courtyard space is developed in an increasing form.The smaller the overall volume of the space,the larger the proportion of courtyard space.The shape of the Dacuo houses is fully considered to be influenced by the overall orientation of the building and has effectively been circumvented.
