摘要

结合第 2次全国土壤侵蚀遥感调查工作的组织程序和作业数据流程，提出了“全流程管理，分环节控制”的数据质量控制和质量保证体系。该体系分为调查前技术培训、省 (自治区、直辖市调查中的质量控制和省级成果验收与全国数据集成等 3大步骤。每个步骤中，又包括必需的环节和具体的内容。实践证明，该数据质量保证体系是行之有效的，基本满足了该次调查工作对数据质量控制的要求，也保证了调查工作顺利进展。

Abstract

Based on the procedure and technological process of the national survey with remote sensing and geographic information system(RS and GISof soil erosion

the system of quality assurance and quality control is put forward

which is named as which managing whole technological process

taking practices of quality control in every link”. The system included three steps

which are the technological training before the survey

quality control during the investigation of provinces

and checking and accepting the works of provinces and integration of digital maps of whole country. Every step included necessary links and measures. The practice proved that the system was effective which could meet the demands of the national survey of soil erosion.
