- 摘要:
- 应用TM图像数据提取鄱阳湖地区沙地资源信息，采用目视解译的方法结合野外调查获得了鄱阳湖地区沙地资源的动态变化，得出1999年鄱阳湖地区的沙地面积为217.6km2，比1991年减少了142.9km2。分析了鄱阳湖地区泥沙的主要来源，提出了充分治理和开发沙地资源、保护生态环境的具体措施。
- Abstract:
- The sandy land information was obtained by TM images from Landsat-5 and the dynamic variation of sandy land was analyzed by method of visual interpretation combined with field investigation in Poyang Lake region.The results shown that there was 217.6 km2 sandy land in Poyang Lake region in 1999, which is 142.9 km2 smaller than that in 1991.The main sources of sand and silt was analyzed, and then the detailed measures to control and to utilize the sandy land and to protect the ecologic environment were put forward.
