摘要
基于2020年乌鲁木齐市POI数据,采用ArcGIS空间分析方法,通过构建"影响力—空间面积"权重模型定量识别了城市"三生"空间,并解析其分布特征。结果表明:①乌鲁木齐市城市"三生"空间分布格局与城市功能分区相符合。②"三生"空间分布呈现"大分散、小集中"的特征,各区分布不均衡,总体上形成"生活空间较强凝聚、生产空间相对集中、生态空间均匀分散"的格局。③生活空间呈"西北—东南"走势,呈现内部连片、外围组团状分布特征;生产空间呈现"东西两翼"的空间格局,沿交通干线布局,向产业区集聚;生态空间呈点状分布,"中心—外围"差异明显。
Based on POI data of Urumqi City in 2020,this paper quantitatively identified and analyzed distribution characteristics of“production-living-ecological”space by using ArcGIS spatial analysis method and“influence-space”binary weight model.The results showed that:①The spatial distribution pattern of“production-living-ecological”in Urumqi City was consistent with the urban functional zoning.②The“production-living-ecological”space of this city presented“wide dispersion and dense centralization”distribution characteristics.And the distribution of each district was not balanced.On the whole,this city showed“strong cohesion of living space,relatively concentrated production space,evenly dispersed ecological space”spatial distribution characteristics.③The living space showed a trend of“from northwest to southeast”distribution.The characteristics of internal contiguous and peripheral cluster distribution of living space distribution were also uncovered.The production space presented a spatial pattern of“east and west wings”,distributing along the main traffic lines and gathering towards the industrial area.The ecological space was distributed in point shape,and“center and periphery”difference was obvious.
