运用计算机技术,进行数据处理、图像制作和空间分析,探讨中国丹霞地貌的空间分布与地形、气候、红层等要素的关系。首先利用Google Earth4软件对我国799处丹霞地貌进行空间定位,获得它们的经纬度;再使用Free Version ofGPS Track Maker#13.6软件提取空间数据;然后在Excel中对数据处理、保存;最后使用ArcGIS 9.2编辑保存的数据,进行制图和空间可视化分析。通过以上研究发现:中国丹霞地貌主要集中分布在青藏高原的东北部-东南部-四川盆地西南部、武夷山-南岭、太行山-巫山-雪峰山3个地带。 更多还原

【Abstract】 The relationships among distributions of Danxia landform in China and natural elements such as terrains, climates, and red beds were explored by the use of computer technology through data processing, image-making, and space analysis. Accurate longitudes and latitudes for 799 Danxia Landform sites were obtained by Google Earth first, through spatial positioning. Those spatial data were then extracted by applying the free software, GPS Track Maker, version 13.6. After the data were processed and ... 更多还原
