摘要
就1:20万海南岛SOTER数据库的组织与设计过程进行了详细的探讨。剖析了中尺度SOTER制图的原则与方法、属性数据的采集及组织管理思路等。在此基础上拟订了研究区制图单元指标体系,完成了研究区制图单元的区分与制图,构建了研究区1:20万SOTER数据库,包括中心数据库与附属数据库。该研究在理论上对于发展与完善SOTER方法论体系、促进其推广与应用有着积极的意义。在实践上对于促进海南岛土地资源的科学决策管理与持续利用具有参考价值。
Designing process of Hainan Island's soter database at 1 200 000 scale is discussed in detail here. It analyses the principles and methods of middle scale SOTER mapping, and train of thought of collecting and organizing the attribution data of the mapping units. On the basis of these, we have drawn out the dividing indices systems of mapping units of studying area, completed the dividing and mapping of SOTER units of the studying area, and constructed studying area SOTER database at a scale 1 : 200 000, including a central database and a accessory database. The study will play positive roles in making SOTER methodology perfect and making scientific decisions in Hainan landuse management.
