摘要
城市人居环境建设是推动黄河流域高质量发展的重要内容,也是实现流域人地关系协调的综合表征。本文基于“生产—生活—生态”功能视角构建城市人居环境评价指标体系,综合运用灰色关联-TOPSIS、空间马尔科夫链、地理加权随机森林(GWRF)模型等方法,深入剖析2011—2020年黄河流域城市人居环境动态演变与影响机制。结果表明:①黄河流域城市人居环境总体呈现出东高西低、南高北低的正向聚集空间分布特征,形成以西安市、郑州市、青岛市和济南市为主的人居环境高值区,以铜川市、中卫市和嘉峪关市为主的人居环境低值区。②黄河流域城市人居环境动态演变具有显著的空间交互作用和动态转移趋同现象,人居环境等级存在一定程度的转移路径“自身锁定”效应,人居环境水平通常只在相邻等级间发生转移,发生跨等级转移的概率较小。③人居环境是经济水平、环境质量和社会资源综合作用的结果,经济水平占据主导地位,消费水平、空气质量和交通资源等是影响城市人居环境水平的主要因素。④GWRF模型能够有效解释影响因素在局部地理空间上所表现出的空间异质性特征,可成为人居环境研究领域一项更有效的解释工具。本文深化了人居环境研究理论方法,并为推动黄河流域人居环境建设和高质量发展提供科学参考。
The construction of urban human settlements is an important content to promote the high-quality development of the Yellow River Basin,and it is also a comprehensive way to realize the coordination of human-earth relations in the watershed.This paper constructs an urban human settlements evaluation index system based on the perspective of"production-living-ecological"function,and comprehensively uses the Grey Relation Analysis-Technique for Order Preference By Similarity To Ideal Solution(GRA-TOPSIS)method,spatial Markov chain,Geographically weighted Random Forest(GWRF)and other methods to analyze the dynamic evolution and influencing mechanism of urban human settlements in the Yellow River Basin(YRB)from 2011 to 2020.The results show that:(1)The urban human settlements in the YRB generally exhibits the positive spatial distribution characteristics of"high in the east and low in the west,high in the south and low in the north",forming a high-value area of the human settlements dominated by Xi'an,Zhengzhou,Qingdao and Jinan,and a low-value area of the urban human settlements dominated by cities of Tongchuan,Zhongwei and Jiayuguan.(2)The dynamic evolution of the urban human settlements in the YRB has significant spatial interaction and dynamic transfer convergence.There is a certain degree of"self-locking"effect of the transfer path at the level of the human settlements.The level of the human settlements usually only transfers between adjacent levels,and the probability of cross-level transfer is small.(3)The human settlements are the result of the comprehensive effects of economic level,environmental quality and social resources.The economic level dominates,while consumption level,air quality,and transportation resources are the main factors that affect the level of urban human settlements.(4)GWRF model can effectively explain the spatial heterogeneity characteristics of influencing factors in the local geographic space.It is expected to become a more effective explanatory tool in the field of human settlements research.This paper deepens the theoretical methods of human settlements research and provides a scientific reference for promoting the construction and high-quality development of the human settlements in the YRB.
