摘　　要：钦州港是北部湾地区填海造地最典型的区域之一,探究其填海造地的动态时空过程,测算其内在的驱动力因子,具有较强的科学意义。文章根据收集的Landsat5TM/Landsat7ETM影像数据,借助3S技术,采用归一化水体指数和人机交互式解译相结合的方法,对钦州港2000年～2014年间段填海造地的动态时空演变过程进行了分析。运用灰色关联模型,从土地资源因素、社会因素和经济因素三个方面,选择了7个驱动因子,对钦州港填海造地的主要驱动力进行了测算评定。研究结果显示:选取的7个填海造地驱动因子中,社会固定资产投资完成额对该演变影响最大,关联度为0.85,是钦州港2000年～2014年填海造地的主要驱动力。Qinzhou Harbor is the most typical region of Beibu Gulf reclamation area. Therefore, it is of great scientific significance to explore the dynamic space-time process of marine reclamation land of Qinzhou Harbor and calculate its internal driving force factors. In this study, TM/ETM images from 2000 to 2014 as the data source, under the support of 3S technology, the dynamic changes of marine reclamation land in Qinzhou Harbor was analyzed by the combination of modified normalized difference water index and visual intelpretation. Using grey correlation model, seven driving factors were set from three aspects of the land resource factors, social factors and economic factors, and the main driving force of the changes were calculated and evaluated. The results show that in the seven driving factors, social fixed assets investment amount has a greatest impact on hhe evolution with the correlation of 0.85which is the main driving force of land reclamation in Qinzhou Harbor from 2000 to 2014.
