盐渍土时空变化信息的图谱可视化分析
Visual analysis of saline soil spatio-temporal variation using Geo-information TuPu
摘要
Abstract
The visual analysis of saline soil dynamic change information is still not solved. The analysis method of Geo-information TuPu was used for visual analysis of saline soil dynamic change information in the paper. Spatio-temporal composite unit was put forward as the minimum mapping unit to express the dynamic change of saline soil types. The establishing method of Geo-information TuPu of saline soil dynamic change was studied in this paper. Yinchuan Plain was taken as a research area. Three years (2000, 2004 and 2009) satellite remote sensing images were used for soil salinization mapping. The two-period saline soil dynamic change information TuPus were obtained from 2000 to 2004 and from 2004 to 2009 using GIS superposition analysis. Dynamic change pattern were analyzed by Geo-information TuPu of saline soil dynamic change in Yinchuan Plain. The results can provide a new way for position analysis on the drive mechanism of saline soil evolution.关键词
