摘　　要：常规的水土流失野外调查技术已难以满足现阶段区域水土流失调查工作需求。为探索高效、精准、高质量的水土流失野外调查及数据采集技术,文中在分析区域水土流失野外调查内容、面临问题及需求的基础上;利用"3S"、互联网+、Ovitalmap、智能移动终端等技术,设计了4层架构、7项功能的数据信息采集系统,构建了集多源数据、多维空间、多尺度于一体的水土流失野外调查技术体系,涵盖了数据准备-野外调查-内业整理-数据管理等过程;并以国家级重点治理区沂水县为例,探索了"数据标准化处理-野外信息采集-内业数据管理"等环节协同作业的信息化技术,验证了技术体系在水土流失野外调查中的可行性及高效、精准性。研究成果可为区域水土流失监测、水土流失综合治理、生产建设项目水土保持监测及监督管理等以及地学相关专业野外调查工作提供技术参考。Traditional field investigation technologies have not been able to meet the current needs of regional soil and water loss investigation.In order to explore efficient,accurate,and high-quality data collection methods to satisfy the requirements of soil and water loss investigation at regional level,this study developed a four-layer-frame including an information collection system that has seven differential functions by using utilized"3 S",Internet Plus,Ovitalmap,and smart mobile terminals.Moreover,this frame realized field investigation with multi-source data,multi-dimensional space,and multi-scale,which covers the data preparation,field investigation,data processing,and data management processes.By using the typical county,Yishui,in National Key Management District as an example,this study explored the collaboration of data standardized processing—field data collection—indoor data management.Meanwhile,this research also examined the feasibility,efficiency,and accuracy of this frame in the field investigation of soil and water loss.The results of this study could provide technical supports for monitoring and controlling of soil and water loss,supervision and management of industrial projects,and geoscience related field investigation at multiple spatial scales.
