摘要:
良好的人居环境不仅能对社会经 济发展产生正效应,对居民体验与生态环境 的可持续发展也具有重要意义。梳理相关 研究现状,利用熵权法与地理探测器,对辽 宁省14市20 08—2017年的城市宜居性进行 评价,得出以下结果。一、时间变化。辽宁省 城市人居环境宜居性整体呈波动上升趋势, 于2011年和2016年出现峰值,分别为8.82和 8.48,阶段性特征显著。二、空间分布。辽宁 省城市人居环境宜居性空间差异显著,具体 表现为以沈阳、大连为主的优质人居环境区 和以朝阳、阜新与丹东为代表的欠发达人居 环境区,具有较强的西北—东南方向性特征 以及非均衡变动特征。三、系统分异。辽宁 省城市人居环境五大系统变化差异较大,社 会系统变化幅度最大,其他系统较小;人口 系统和居住系统得分较低,其他系统得分较 高。四、影响因素。对辽宁省城市人居环境宜 居度影响最大的系统依次是支撑系统和社会 系统。支撑系统中基础设施的完善程度与城市人居环境宜居性存在正相关关系;社会系统中,社 会经济发展状况是影响城市人居环境宜居性的重要因素。

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.
