Abstract: |
As the basic support for the residents’ survival and social development, the human
settlements has a positive effect on the development of the city and society. A good human
settlement not only has a positive effect on social and economic development, but also has
important significance for the residents’ experience and the sustainable development of the
ecological environment. Based on the research of urban human settlements in the past, the paper
combs the current research status of urban human settlements habitability and livability, and
uses entropy weight method and geo-detector to study on temporal change, spatial differentiation
and systematic differentiation characteristics of urban human settlements habitability in 14
cities of Liaoning Province from 2008 to 2017. And according to the equal interval method, the
representative year is selected to analyze the influencing factors of urban human settlements
livability. The results of the study are as follows. 1)Time change. The livability of urban human
settlements in Liaoning Province showed a volatility as a whole, with peaks in 2011 and 2016,
at 8.82 and 8.48 respectively. At the provincial scale, the stage characteristics and discrete
characteristics are significant. The first stage is from 2008 to 2012. The overall growth trend is
large, and the change range is large. The difference in the livability in the province is significant.
The second stage is from 2012 to 2017. The occupancy rate showed a gradual upward trend, the
change range was small, and the difference in livability in the province narrowed. Characteristics
of city livability change: during the study period, the largest difference in livability was in the
city of Benxi, and the smallest was in Dandong City. The greater the change in the livability
difference, the more unstable the urban human settlements is. 2)Spatial distribution. There
is a significant difference in the livability space of urban human settlements in Liaoning
Province. The specific performance is the high-quality human settlements environment centered
on Shenyang and Dalian, and the underdeveloped human settlements area represented by
Chaoyang, Fuxin and Dandong, overall ridge distribution; strong northwest-southeast directional
characteristics, which are basically consistent with the trend of economic development;
analysis of livability scores in 10 years, found that its evolution has non-equilibrium variation
characteristics, both time variation and spatial distribution are characterized by non-equal
variation, which is in line with the development of urban human settlements. 3)System differentiation. During the study period, the five major systems of urban human settlements in Liaoning Province vary greatly. From the perspective
of change, the social system has the largest change, and other systems are smaller. From the perspective of development level, the population system
and residential system scores are lower. Other systems’ scores are higher. The population system is greatly affected by factors such as the aging of
the population and the outflow of the population. The social system changes and the level of economic development converge. The environmental
system is related to geographical location and environmental protection investment and industrial development. The change of the residential
system is affected by the population density. 4) Influencing factors. The urban human settlement environment itself has complexities as a complex
giant system, which makes its livability different in space. According to the equal interval method, 2009, 2011, 2013, 2015 and 2017 are selected
as representative years for livability. Analysis of factors affecting the degree. The results show that the system that has the greatest impact on the
livability of urban human settlements in Liaoning Province is the support system and the social system. There is a positive correlation between the
degree of perfection of infrastructure in the support system and the livability of urban human settlements; in the social system, the socio-economic
development status is an important factor affecting the livability of urban human settlements. Other systems, population system, residential system
and environmental system have little effect on the spatial differentiation of urban habitable environment. The reason is that Liaoning’s overall
population system scores are lower, spatial differences are smaller; the environmental system is related to geographical location, environmental
protection investment and industrial development. Since the residential system contains positive indicators and negative indicators, while the
proportion is small, so it contributes less to the spatial difference of urban human settlements habitability. The entropy method was used to evaluate
the livability of urban human settlements, and the geo-detector was introduced into the research on the livability of urban human settlements. The
study on the livability of urban human settlements in Liaoning Province from 2008 to 2017 was conducted. Time variation and spatial differentiation,
system differentiation and influencing factors have drawn some preliminary conclusions, which have enriched the research case of urban human
settlement to a certain extent, and have certain reference significance for the construction and development of urban human settlement in Liaoning
Province. |
