Combined Gini coefficient,relative development rate,location quotient and others with GIS,the imbalance development in space and its evolution trend of Yulin each area from 2001 to 2012,were portrayed from the macro-economic development,urban space structure and transport infrastructure layout. The results showed as follows. Firstly,there existed a significantly imbalance in space which increased year by year in macroeconomic development(especially industrial output)and the urban and rural income levels of the north and south county in Yulin;Secondly,industry specialization characteristics were manifested at the secondary industry in north and the first and third industry in south;Thirdly,the economic development status in south is lower than that in north,as well as the urban spatial structure. The imbalance is the basic reason of the latent social safety problems ,ecological problems of coal mined-out area,the collapse of private lending and the burst of real estate bubble. Based on the analysis above,some measures and notices for further mitigating the city’s imbalance development pattern were given.%运用基尼系数、相对发展率和区位商等方法结合GIS，从经济空间发展、城镇空间结构及基础设施布局三大层面刻画了2001—2012年间榆林市各县区发展的空间失衡性及演变态势。结果表明：榆林市南北县区在宏观经济发展（尤其是工业产值）及城乡收入层面上空间失衡性显著，且逐年加剧。其产业专门化特色在北部表现为第二产业，在南部表现为第一产业、第三产业。榆林市在经济发展地位上表现为“南低北高”，在城镇空间结构上表现为“南少北多”。这一空间失衡是南北贫富极化及其差距下潜伏的社会安全隐患、煤炭采空区生态问题、民间借贷崩盘与地产泡沫破裂等产生的根本原因，并基于此提出了缓解失衡性的战略措施。
