摘 要: 采用《国家人口发展功能区技术导则》确定的指标体系,在250米格网下,计算了全区的人居环境指数(HEI),并进行了空间格局及空间异质性的比较和分析。结果表明:萝岗区的人居环境指数介于24.32~86.06之间,平均人居环境指数为69.27,总体上属于比较适宜区(HEI范围61~80,占88%),局部地区处于一般适宜区(HEI范围24~60,占11%),局部地区属于高度适宜区(HEI范围81~90,占1%)。研究发现人居环境指数高的地方人口密度也相对较大。HEI指数从大到小顺序为:东区街>夏港街>永和街>九龙镇>萝岗街>联和街。萝岗区人居环境适宜度整体分布态势是:从西向东呈带状递增,从低山、丘陵向台地、平原、河谷递增。 Adopting the 'Technical Guideline of National Population Developmental Function Area',to the paper calculated the human environment index(HEI),then comparatively discussed and analyzed the spatial pattern and spatial heterogeneity of HEI in the size of 250m grids.Our results showed that the HEI in Luogang ranged from 24.32 to 86.06,with an average index value of 69.27.Most of the whole are belonged to a more suitable area(HEI: 61-80,accounting for 88%);some parts of the area belonged to the general suitable area(HEI: 24-60,accounting for 11%);a few parts of the areas belonged to the highly suitable area(HEI: 81-90,accounting for 1%).Basically,the parts with large HEI are correlatied with high population density.The streets of HEI in luogang in descending order is: Dongqu>Xiagang > Yonghe > Jiulong > Luogang > Lianhe.The features of the HEI distribution in Luogang show a stepped-pattern from west to east,ascending from the low mountains and hills to the plateaus,plains and valleys.
