摘要

建立准确可靠、精确可用的中国土壤侵蚀背景数据库是进行全国或区域范围内土壤侵蚀定量评价及土壤侵蚀时空特征研究的基础工作

也是其重要的手段和途径。就小比例尺全国土壤侵蚀背景数据库的建立过程

探讨了该类数据库在ARC/INFO软件系统上实现的技术方法

以及数据精确程度的控制问题。

Abstract

The work of establishing environmental context database of soil erosion of China accurately and precisely

is essential in the models of quali tatively accessing the soil conservation at the whole country or region field.The work is also an important means to study the characteristics of temporal and spatial scale of soil erosion. Based on the procedure of building environmental context database of soil erosion of China in the 1∶4000 000 scale

the executive means of the database like this on computer and the accuracy control of the data with the support of ARC / INFO is mainly discussed.
