摘　　要：为了分析二调与三调之间土地资源的变化和流向,本文利用三调初步成果数据与二调数据进行空间分析,统计各地类的面积和流向等。在数据分析和统计的过程中,经过多次试验,解决了线状地物面状化、叠加分析、椭球面积计算、流向统计等多个关键环节中的问题,快速准确地完成了全省数据分析和统计,并对泉州市的数据进行了更为详细的分析。In order to analyze the change and flow direction of land resources between the second national land survey and the third national land survey,the preliminary results of the third national land survey and the second national land survey data are used for spatial analysis,and the area and flow direction of land use class are counted.In the process of data analysis and statistics,through many tests,the problems in many key links,such as linear surface feature planarization,superposition analysis,ellipsoidal area calculation,flow direction statistics were solved,and the provincial data analysis and statistics were completed quickly and accurately,and the data of Quanzhou city were analyzed in more detail.
