土壤可蚀性因子空间变异表述系统研究及应用

Research and application of expression system for spatial variability of soil erodability factor

为推动我国土壤侵蚀预测预报技术的发展,利用ArcGIS Engine二次开发的优势,构建了基于ArcGIS平台的土壤可蚀性因子空间变异表述系统。该系统具有快速、简洁加载空间数据并对空间数据进行空间插值分析、精度验证以及要素空间变异表述等特点。可对土壤因子进行高效查询和分析研究,提高土壤侵蚀研究的科学性、准确性,使防止水土流失工作的规划、管理和决策更加科学化、数字化,具有较大的应用潜力。

To promote the development of forecasting technology of soil erosion,the expression system for spatial variability of soil erodability factor is structured based on ArcGIS by taking the advantage of secondary development of ArcGIS Engine technology.The system is characterized by loading of spatial data quickly and easily,spatial data interpolation analysis,accuracy verification and spatial variability expression of elements.As a result,the system can be used to inquiring and analyzing the soil factor efficiently,assisting the research on soil erodability factor,and improving the scientificity and accuracy of the soil erosion research and makes the planning,management and decision-making of soil-water loss conservation more scientific and digitalizaiton.
