From the concept of production-living-ecological function , this paper has built the production terri-torial utilization quality index (PTQI), living territorial utilization quality index (LTQI), ecological territorial utili-zation quality index ( ETQI) with a total of 12 subtype indices and several elements of the comprehensive quality of territorial utilization ( TQI) .On the basis of the data in 2012 in provincial unit , comprehensive evaluation method is used to calculate China ’ s territorial utilization quality and type characteristics .The results has showed that the TQI is relatively low and it has showed differentiated in spacial distribution .PTQI and LTQI in the east are higher than that in the middle , and that in the middle are higher than that in the west .ETQI is higher in the northeast areas and the southeast coastal areas .This paper can give suggestion to the development of production space with intensive and effcient use , the living space with livable and the ecological space with green mountains and clear water .%目前城镇化进程中出现了城乡不协调、区域不均衡、生态破坏严重、国土空间利用质量低下等问题。为实现集约高效的生产空间、宜居适度的生活空间和山清水秀的生态空间，基于“三生”功能的理念，构建国土空间利用质量综合评价指数及其子系统生产、生活和生态空间利用质量指数；基于2012年中国内地省级截面数据，运用综合评价方法分析全国层面和省级层面国土空间利用质量综合评价指数的特征。结果表明：全国层面的“三生”空间利用质量不高，在省级层面的国土空间利用质量综合评价指数则具有显著的空间分异特征，东部地区的生产空间利用质量指数和生活空间利用质量指数高于中部地区，中部地区的又高于西部地区；而生态空间利用质量指数高值区主要集中在东北地区和东南沿海地区。
