中文摘要：
基于县域单元维度，运用GIS空间分析法和基于PSR模型的协调度测度法对广东省城市土地利用绩效空间差异进行研究。结果表明：广东省土地利用效益绩效和效率绩效空间集聚特征显著，而公平绩效则相反；综合绩效的空间集聚可划分为热点区域、冷点区域、异质冷点及异质热点区域4种类型，热点区域和冷点区域的分布面积最大，稳定性明显优于异质值区域；土地利用绩效协调度格局呈现明显的与广东省社会经济地域空间结构相耦合的“中心-外围”结构。协调度格局与综合绩效格局总体相协调，但并不呈单纯的正相关关系。
英文摘要：
With the rapid industrialization and urbanization in China, problems in urban land use, such as inefficient use and management of land, are getting more and more serious, that may impede urban development. The purpose of this paper is to examin the spatial discrepancy of county urban land use performance in Guangdong. GIS spatial analysis and PSR model based on coordination degree are employed to make the research. The conclusions are that： the discrepancy of urban land use performance in different regions is obvious, the effectiveness performance and efficiency performance show a feature of high spatial agglomeration, while the equity performance is relatively scattered. A similar spatial distribution pattern of the effectiveness performance and the comprehensive performance can be found. The spatial agglomeration of the comprehensive performance can be divided into 4 types, the hot-spot areas and cold-spot areas are widely and steadily distributed. The coordination degree of land use performance presents spatial structure of Guangdong. a ＂center-periphery＂ structure, which coincides with the
