【摘要】 SOTER是土壤-地体数字化数据库(Soil and Terrain Digital Database)的简称。SOTER把土地看作由地形和土壤个体组成的自然实体的组合，据地形、岩石、地表形态、坡度、母质和土壤，划分出相对均一的单元对区域土地进行辨识。以这种方式分辨的SOTER单元，可作为不同比例尺的土壤和地形体标准数据的储存和调用的框架。SOTER为其数据库建立制订了一套系统化、标准化的规则，不仅包含有关于土壤和地形体的数据库，还涵盖了气候、植被、土地利用和参考文件等辅助数据库，能为环境的开发、管理和保护提供所需的标准化的地图和表格信息，可用于开展多种专题的研究如全球变化、土地评价、环境评价等。当前SOTER方法已被国际上认可，成为土壤与土地可持续利用研究中的一个前沿和热点。 本研究以地理信息系统(GIS)为技术支撑，以建立福建省1：20万中比例尺SOTER数据库和漳浦样区1：1万大比例尺SOTER数据库为目标，结合福建省实际情况，收集、编制多种专业图件和资料，以地貌图、岩性图、坡度图、土壤图为主要要素图，划分出地形体图、地形体组分图和土壤组分图三级图斑，并建立相应属性数据库，同时建立气象气候数据库、土地利用数据库、参考文件数据库三个辅助数据库。运用AVENUE语言编写程序，实现大、中比例尺SOTER数据库的衔接。此外，本研究以漳浦样区1：1万SOTER数据库为数据源，作了初步应用探讨，运用景观生态学及主成分分析方法，分别研究漳浦样区土地利用现状和土壤分类。本研究对区域SOTER的建立及其应用的探索和积累的经验，对资源可持续利用和管理具有重要意义。更多还原

【Abstract】 Based on the space differentia in topography, rock, gradient, parent material and soil, Soil and Terrain Digital Database(SOTER) takes land as the combination of natural entity composed of relief and soil, recognizing the regional land according to terrain, rock, topography, slope, parent material and soil. In this way, the SOTER units can be used as the framework of the saving and using soil and relief information in all kinds of scales. SOTER formulates a suit of regulations with systematization and standardization for the database, including not only the databases about topography and soil, but also climate, landuse, vegetation and reference file assistant databases. SOTER can provide the standardized maps, chart and tables for protection, administration and exploitation of resources and environment. SOTER can be broadly applied in many fields such as the global change appraising, environment evaluation and so on. Currently SOTER has been authorized and become one of hotspots in the studies of soil and sustainable use of land.Backed by the technology of GIS, the study builds Fujian SOTER database in a scale of 1:200000 and Zhangpu SOTER database in a scale of 1:10000, selects and compiles many kinds of thematic maps, such as the relief map, lithology map, gradient map and soil series map, makes terrain, terrain component and soil component three level SOTER units, and sets up corresponding attribute database, as well as climate database, landuse database, reference file database three assistant database. With AVENUE programming language, the two different scales databases are connected.In order to explore the practical use of SORTER, the study uses the SOTER built in scale of 1:10000 as the data resource and the methods of Landscape Ecology and Principle Component Analysis to study the local landuse and soil classification separately. The study provides experiences to build regional SOTER, and has great significance in sustainable utilization and management of regional natural resources.更多还原
