Urban Parks and Population Coordination in the Yangtze River Delta Region Based on SetPair Analysis |

Abstract: |
The Yangtze River Delta is the pilot area of China’s urbanization process, and a typical
area of the contradiction between park resources and population demand, which has entered a new
stage of high-quality and deep integration development. The spatial agglomeration of urban parks
and the supply of high-quality public services have increased the overall attractiveness of the living
environment in the Yangtze River Delta and enhanced the people’s sense of access and happiness.
The coordinated development of urban parks and population is an important symbol the high-quality
development of human settlement environment in the Yangtze River Delta.
In this paper, 41 prefecture-level and above cities in the Yangtze River Delta are taken as
the research units, divided into two dimensions: parks system and population system. The park
dimension selects some indicators to measure the matching relationship between park area and
population, to characterize the spatial pattern of park distribution, to match park service capacity
with population. The population dimension selects some indicators to reflect population density
and agglomeration, population distribution characteristics, and the quality of life of residents under
a specific space-time background. An index system is constructed to investigate the coordination
relationship and evolution characteristics of “park-population” in cities of the Yangtze River
Delta. Then, by introducing the uncertainty theory and using the coordination evaluation model
of identical-discrepancy-contrary connection degree and set pair potential in set pair analysis, this
paper quantitatively evaluates the coordination between parks and population in the Yangtze River
Delta from 2006 to 2019 in terms of system coordination, difference degree and coordination ability,
and explores the coordinated development relationship between park and population system and its
internal elements, as well as the degree of development coordination among the city circles in the
Yangtze River Delta.
The results show that: 1) From the overall development trend of the Yangtze River Delta region,
the two systems of parks and population have turned from opposition to identity, maintaining a
positive development trend and coordination tends to be better. Urban parks and population in the
Yangtze River Delta are generally coordinated and mutually reinforcing, but there are uncertainties
in the coordinated development, which need to be paid attention to. 2) From the perspective of the
coordination relationship between parks and population, the development of various types of urban
subsystems of general coordination, basic coordination and weak maladjustment is not balanced, and
the coordination difference is large. The coordination of the parks system is generally better than that
of the population system, in which the coordination influence of the total park size and allocation
pattern factors is generally strong. The population living standard factor has been dominant in
population system for a long time, and the stability of population quantity and structure is not good.
3) From the perspective of the spatial-temporal evolution of the coordination ability of “one core and
five circles” in the Yangtze River Delta, the coordination ability of parks and population in the “one
core and five circles” urban agglomeration maintains a positive coordinated development trend in
time sequence, rising in fluctuations; there are obvious differences in coordination ability between
circles in space, Hangzhou and Ningbo metropolitan areas are in the lead, while Shanghai is in the
poor position.Further planning suggestions are put forward: 1) Good coordination should be maintainedbetween the parks system and the population system in the Yangtze River Delta, as well as between the elements within the two systems, to form a pattern of
simultaneous development and improvement. It should optimize the size of the population, attach importance to population mobility, and attract high-quality
population. The population and structural characteristics should be taken as the basis for the allocation of parks resources to optimize the park layout and
promote the upgrading of park services. 2) According to the specific conditions of different circles and cities in the Yangtze River Delta, differentiated parks
and population control measures should be formulated to balance the differences in regional development coordination. It should increase the total amount of
urban parks in Shanghai, coordinate the rational allocation of system elements among the five circles of the Yangtze River Delta urban agglomeration, and
implement the equalization of public services. 3) It should promote the role of parks in the construction of the quality of human settlements in the Yangtze
River Delta and ensure effective coordination with the population by continuously improving the scale, structure and spatial quality of the parks, paying
attention to the different needs of different groups to ensure the accessibility and fairness of the parks.
It’s expected that it will provide a scientific basis for the optimization of park system, the balance of human-land coordination and the healthy
development of urbanization in the Yangtze River Delta, and the results can also play a reference role in the sustainable development of parks and population
in similar regions. |
