【摘要】：针对在湿地动态变化监测中,经典的土地利用转移矩阵无法实现湿地类型变化信息的定位可视化表达的问题,提出了一种新的时空变化信息的可视化分析方法。利用由空间单元和时序单元集成的时空复合单元建立转移图谱单元分类体系,较好地记录每一个图谱单元湿地类型的起始和终止状态,实现了湿地时空变化信息的定位表达;基于遥感制图和地学图谱的湿地空间演变规律特征图谱,采用图表和图谱的形式展示湿地类型变化的数量及空间位置变化信息,实现了湿地时空变化的可视化表达。基于银川平原湿地的实验结果表明:该方法能够清晰、直观地显示1999—2013年期间银川平原湿地的时空变化,能够为该地区合理利用湿地资源提供科学的理论依据。
[Abstract]:In order to solve the problem that the classical land use transfer matrix can not realize the location and visual expression of wetland type change information in wetland dynamic change monitoring. In this paper, a new visual analysis method of spatio-temporal variation information is proposed. The classification system of transfer map unit is established by using the spatio-temporal composite unit which is integrated by spatial unit and temporal unit. The start and end states of each map unit wetland type are well recorded, and the location and expression of wetland spatiotemporal variation information are realized, and the characteristic map of wetland spatial evolution law based on remote sensing mapping and geoscientific atlas is presented. The visualization of temporal and spatial changes of wetland is realized by displaying the information of the quantity and spatial location of wetland type change in the form of charts and atlas. The experimental results of Yinchuan plain wetland show that the method is clear. The temporal and spatial changes of the wetland in Yinchuan Plain from 1999 to 2013 can provide a scientific theoretical basis for the rational utilization of wetland resources in this area.
