Table 1 Types of spatial sequences. Three types of spaces, i.e., enclosed spaces, enclaved spaces and open spaces, are summarised and identified, including ten subtypes of spatial sequences
Types of spaces | Spatial patterns | Characteristics | Properties |
|---|---|---|---|
Enclosed | A: the level of accessibility, area < 50 m2 the level of visibility, area < 50 m2 | Spatially centripetal inwards and enclosed | Small area of both level of visibility and accessibility; the space is both closed and centripetal |
B: the level of accessibility, area < 50 m2 the level of visibility, area = 50–490 m2 | with diffusion, which induces visitors’ movements | ||
C: the level of accessibility, area = 50–490 m2 the level of visibility, area = 50–490 m2 | Inwards and stable | ||
Enclave (Semi-open) | D: the level of accessibility, area < 50 m2 the level of visibility, area = 490–9,500 m2 | Extroversion, induces movements | Fewer areas with relatively high levels of accessibility; more areas with relatively high levels of visibility The view is more open |
E: the level of accessibility, area < 50 m2 the level of visibility, area = 9,500–19,400 m2 | Outwards facing, wide-open views | ||
F: the level of accessibility, area = 50–490 m2 the level of visibility, area = 490–9,500 m2 | Relative spatial stability; inwards spatial equilibrium | ||
G: the level of accessibility, area = 50–490 m2 the level of visibility, area = 9,500–19,400 m2 | Relatively stable, with ‘borrowed landscape’ | ||
Open | H: the level of accessibility, area = 490–9,500 m2 the level of visibility, area = 490–9,500 m2 | Relatively high level of openness | The level of accessibility and the level of visibility are both high. Weak sense of spatial enclosure |
I: the level of accessibility, area = 490–9,500 m2 the level of visibility, area = 9,500–19,400 m2 | Open spaces | ||
J: the level of accessibility, area = 9,500–19,400 m2 the level of visibility, area = 9,500–19,400 m2 | Blurred spatial boundaries; vast |
