摘要:
在利用GIS和RS技术进行区域土壤侵蚀调查时，可以采用栅格数据结构来判别，文章运用实例分析了基于栅格数据结构进行侵蚀强度判别的有关技术和方法，包括侵蚀因子值的提取以及侵蚀强度判别的方法等。结果认为基于栅格数据结构的判别方法能够精细地反映土壤侵蚀在微小领域上的差异。从动态监测和趋势预测角度分析，采用栅格数据结构的判别方法更方便、更有利于快速提取侵蚀因子和进行土壤侵蚀动态分析和预报。
Abstract:
The raster special data structure is used in surveying the regional soil erosion survey and mapping soil erosion intensity atlas based on the RSGIS(Remote Sensing and Geographic Information System).The methods and techniques were discussed,including how to differentiate erosion intensity.According to the analysis results based on the raster data structures,the methods can be used to estimate the soil erosion intensity. From the dynamic monitoring and trend forecasting,it is convenient and more rapid for raster to capture the value of erosion factors,to analyze dynamic pattern and to predict the development.
