集土壤与地形数据于一体的 SOTER 数据库,较单一的土壤或地形数据库包含有更多的信息,这能够为日益锐化的人口与自然资源之间的矛盾的解决提供更有力的数据支持.而全国尺度 SOTER 数据库的建立将能够从国家尺度为该矛盾的解决提供更多的支撑.本文利用新的数据源(SRTM)和数字土壤制图技术,定量化地构建了中国1:100万 SOTER 地形体.通过本研究发现,采用 90 m 分辨率的SRTM数据来构建1:100 万的 SOTER 地形体的结果是令人满意的,可以实现无缝接边,与传统的方法相比,更准确、更快速、更一致.同时,也提供了一个定量化构建小比例尺地形体单元的方法,为小比例尺 SOTER 数据库的建设提供方法论上的支持,对实现农业和环境资源的有效管理具有重要的作用.

SOTER as the combination of soil,landform and lithology contains more information than single soil or landform database.SOTER can provide more robust supports for the solution of the increasing contradictions between human and natural resources.This paper described a procedure to delineate SOTER Terrain Units on 1:1 M scale of China by using new data (SRTM) and new digital soil mapping technology.The results showed that the procedure was suitable to delineate SOTER Terrain Units on 1:1 M scale of China based on SRTM with 90 meter resolution.Compared with the traditional methods,the procedure can realize seamless edge match,get more accurate,consistent and faster results,meanwhile it can provide a quantitative methodology to delineate SOTER Terrain Units on small scales,which is very important to realize the effective management of agriculture and environmental resources.
