| 摘 要： | 基于自然与人文多重栅格数据,构建人居环境质量综合指数评价模型,分析2015年关中平原城市群人居环境的空间分异格局,并对人口分布与人居环境质量的协同性进行探讨。结果表明:(1)人居自然环境呈现出自东向西,由山地、高原向平原、谷地依次递减的空间分布格局,受地形影响最为明显,地形起伏度与人居自然环境呈负相关关系。(2)人居人文环境表现出平原低、山区高,城镇高于乡村的空间分布格局,受城市行政层级影响显著。(3)关中平原城市群人居环境综合质量指数介于0.216~0.716之间,呈现出以关中平原、汾河谷地向外梯级递减的带状空间分布格局。(4)关中平原城市群人口密度与人居环境质量空间分布显著一致,总体呈现出平原高于山地,城市高于乡村的空间分布规律,人居环境质量越高,人口密度越大,土地利用也越充分。

| Abstract: | Based on the multi-grid data of nature and humanities,this paper constructed the comprehensive index of human settlement environment quality,analyzed the spatial differentiation characteristics of human settlement environment of the urban agglomeration in Guanzhong Plain in Shaanxi and Shanxi Province,China in 2015,and discussed the correlation between population distribution and human settlement environment quality.The results showed as follows: (1) The natural environment of human settlements shows a spatial distribution pattern of successive diminishing from the east to the west,from the mountainous areas and plateaus to the plains and valleys,which is mostly affected by topographic factors.The terrain relief amplitude has a negative correlation with the human settlement environment.(2) Affected by the urban administrative level,the cultural environment of human settlements showed a spatial distribution pattern of the plain areas being low,the mountainous areas being high and it being higher for the cities and towns than the country areas.(3) The comprehensive index of human settlements environmental quality of the urban agglomeration in the Guanzhong Plain ranges from 0.216 to 0.716.The spatial distribution displayed in strip shapes which was gradually descended from the Guanzhong Plain to the Weihe Valley to the outer fringes.(4) The population density of the urban agglomeration in Guanzhong Plain is significantly consistent with the spatial distribution of human settlement environmental quality.The higher the quality of human settlements is,the greater the population density and the more adequate land use are. |
