坡地“常全影”空间属性与坡度及坡向相关性分析

The Correlation Analysis between the Spatial Attributes of Constant-holistic Shadow Space and the Slope Degree and Aspect of Sloping Ground

夏热地区为室外公共空间的人群活动构建“常全影”空间十分有利,但不同坡度和坡向明显影响“常全影”空间的平面形态和大小,故须探明其相互之间的关联性特征,以便促进坡地“常全影”空间的有效构建。以广州地区、常见典型长方体建筑构影体为例,运用Eoctect软件的日照阴影模拟及可界定的“常全影”空间,揭示了长方体建筑构影体在坡面上所构的“常全影”空间在其形态、方位及面积大小与不同坡度、坡向之间的关联性特征,并阐明其在日期和时段上的差异性。以期为夏热地区城区中的坡地“常全影”空间构建,提供科学依据和有效指引。

It is very beneficial necessary to construct a kind of Constant-holistic Shadow(CHS)space for grouped activities in outdoor public spaces in hot summer areas.However,different slope degrees and aspects significantly affect the shape and size of the CHS space,so it is necessary to explore the correlation characteristics between them,to promote effective construction of the CHS space on slope lands.In this paper,taking a typical cuboid building in Guangzhou as an example,using Autodesk Ecotect Analysis to simulate the sunshine shadows and the defined CHS spaces formed by the example cuboid building on the slope surface,the correlation characteristics between the shape,location,size of the CHS space and the different slope degrees and aspects have been revealed,and the differences in the date and time-period scale have been clarified,to provide scientific basis and effective guidance for the construction of Constant-holistic Shadow spaces in sloping urban area in hot summer area.
