摘要
根据土壤及地形(SOTER)数据库基本原理和方法建立1∶25万SOTER数据库,重点研究和修正大中比例尺SOTER主地形体划分指标体系,提出海拔高度分组指标、坡度分组指标和地势起伏强度分组指标,并利用上述3个指标组合计算出样区SOTER主地形体组分(中坡度丘陵、低坡度山体台地、山谷、中坡度山体、山前倾斜平原和冲洪积平原),以进一步发展和完善SOTER数据库理论方法体系。同时,SOTER数据库的建立使原有的历次土壤普查、国土资源详查的资料信息化,使之服务于土地资源的评价、管理与保护。
Soil and terrain spatial and attribute digital databases(SOTER) at a scale of 1∶250000 was studied according to the theory and methodology of SOTER database. The research focused on exploring suitable landform indexes for this scale. The classification of elevation, slope and relief index was produced. Based on elevation, slope and relief index, landform of research area were calculated and delineated, they are medium slope hill, low slope mountain and mesa, valley floor, medium slope mountain, gentle slope floor and alluvial-diluvial plain. The construction of SOTER makes it possible that historical soil and land survey data, which had been set aside without usage, was transformed into information system. These data can serve for land evaluation, land management and land protection. The theory and methodology of SOTER was also extended by this research, this showed an example of the application of SOTER methodology to small scale.
