中文摘要：

城市住房与居住空间格局深刻反映着城市地域上的社会经济状况,是认识城市及其空间结构的重要视角。从住房租金考察居住空间分异是城市居住空间研究的新领域,利用住房租金特征指标研究西安城市居住问题,用定量方法揭示西安市居住空间的分异规律。依据西安市主城区2014年7月份的964处住房租金交易信息,借助GIS、SPSS、Sufer等软件对西安市主城七区住房租金的空间分布以及影响因素进行分析研究。研究结果表明：（1）西安市可供出租的住房主要集中在城市中心偏南的雁塔区、碑林区和莲湖区;（2）西安市住房租金呈现出＂中心高、四周低＂的空间格局与＂居住郊区化＂的趋向性,雁塔区租金普遍较高,最高值出现在曲江街道办,长安区租金普遍较低,最低值出现在引镇街道办;（3）通过回归分析,综合西安市主城七区所有租房交易数据,得出影响租金影响因素主要有住房配套设施、装修情况以及商服设施等。本研究具有一定的实用价值,可以为制定相关政策提供理论依据。
