| Research on the Suitability Evaluation of Urban Greenway Layout under the Background of Park City |

| Abstract: |
| With the gradual improvement of residents' requirements
for the quality of slow moving space, it is particularly important to
build a green, open, inclusive and shared urban greenway. However,
at present, China's greenway still has problems, such as imperfect
network and single functional value. Under the background of
Park City, urban greenway continues to upgrade in the design
concept and functional value of urban public space, combined with
multi-source big data, construct the suitability evaluation index
system and technical route of urban greenway layout under the
background of Park City. Finally, taking Fengdong area of Xi'an as
an example, the "departure-route-destination/node" is identified by
big data analysis, and the road with the highest suitability score is
superimposed. The final result of urban greenway layout is obtained
through optimal path analysis and correction. This result improves
the accessibility of recreational resources, plays a good role in
connecting public transport, and provides a good line for slow
travel. It can provide some reference for the construction of green
and shared urban greenways under the concept of Park City in the
future. |
