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.
