| Abstract: |
| With the development of the social economy, leisure has become an important part
of people’s life after meeting their basic survival needs. The urban leisure function has come
to play an increasingly significant role. Up to date, with enormous contributions of big data
technology in urban and rural planning and research, more research methods and data support
are provided for relevant urban researchers. Among them, urban interest points have been
gradually applied to scientific research as point-like geospatial data representing real geographic
entities, which mainly contain spatial and attribute information of these geographic entities.
Hefei, the capital of Anhui Province, is located in the central part of Anhui Province and is
a sub-central city of the Yangtze River Delta urban agglomeration. Based on the collection
and sorting of POI data in Hefei urban area, this paper selected six representative leisure
function types serving residents and tourists, namely, catering, commercial service,
entertainment, sports and fitness, hotels and scenic spots. In this study, POI data were
obtained from Amap. The time node is February 2017. According to the types of urban
leisure functions, a total of 131 503 pieces of data were crawled.
With the help of GIS software, nuclear density analysis was carried out on the data, and
the spatial distribution features of various leisure function types have been studied. It was
found that the most densely populated areas for hotels are areas with urban transportation
hub and core business districts. In addition, areas with a large floating population, such as
university town and the center of the new city zone tend to become the secondary hotel dense
area. Catering and entertainment facilities are multi-core distributed in Hefei urban area, which
is the central area and densely populated area of residents’ activities in each area. The layout
of commercial service facilities in Hefei is relatively uniform, with many small core areas,
forming a commercial service space network system featuring multiple levels in Hefei urban
area. Fitness facilities in Hefei as a whole show an average distribution and the total number is
relatively small. POI of scenic spots is the least in number, which mainly concentrated in the
park around city. The rest are scattered, with a certain traffic distance between them, thus their
spatial layout has certain randomness.
According to the various types of urban leisure facilities, the previous study was based on
six categories. On the basis of the analytic hierarchy process(AHP), a single-level model can
be constructed to judge the relative importance and evaluation weight of each element. Yaahp
is a software with the analytic hierarchy process to assist modeling and calculation. In this
paper, a single-level leisure function evaluation model was built through this software, and the
weights of various leisure facilities were calculated. The final result showed that the maximum
proportion of leisure facilities was 0.32, followed by 0.25 for scenic spots, and the minimum
weight was for commercial services and hotels.Based on the above research and the final comprehensive superposition analysis with GIS software, the spatial distribution characteristics of the
overall urban leisure function have been studied. It was found that the urban leisure function in Hefei is still dominated by the old downtown,
where plenty of traditional commercial districts, various entertainment and scenic tourism resources are clustered. The secondary leisure function
core area is the area with a large floating population, mainly represented by Hefei railway station, bus station and other transportation hubs and the
vicinity of urban colleges and universities. Some areas far away from the urban area, due to the traffic, are separated from the radiation range of
the leisure function area in the city center, and gradually form the leisure function core area in the core of their own, such as the central area of the
university town and the center of Binhu New Town.
Considering the above results, we can see the main problems existing in the distribution of leisure functional areas at present. First, the overall
distribution is extremely uneven, and the distribution of leisure functional areas in urban areas is mainly concentrated in the park around city.
Second, there are not many types of leisure functions, most of them are commercial service and entertainment facilities, while leisure resources
such as sports and fitness as well as scenic spots, which account for a high weight in the evaluation system of leisure functions, are relatively few.
Third, the development of urban leisure tourism function resources like scenic spots is insufficient.
Given the above research and conclusion, this paper has put forward the planning suggestions for urban leisure functional areas in Hefei: 1.
Reasonable planning of urban leisure functional areas to promote the multi-level balanced development; 2. Sorting out urban leisure elements to
enhance the urban leisure functional system; 3. Taking advantage of superior resources to create characteristic leisure functional areas. |
