南京地区幅卫片土壤解译与制图研究

卫片遥感技术在宏观范围内对土壤资源进行调查制图的优越性,主要表现在时间快,人、物力省,工作重点大部分转移到室内来进行。与经典法相比,能够保证该比例尺所要求的土壤制图单元、图斑数量和界线精度。 本文所完成的卫片南京幅土壤解译成果是采用光学和计算机等多种处理获得的卫片影象,结合建立野外景观-土壤-影象特征三者相关性典型样区,再藉助地质资料等多种途径完成的。

STUDY ON THE APPLICATION OF INTERPRETATION AND MAPPING OF SOILS BY USING LANDSAT MSS AT NANJING IMAGE

The advantages of remote sensing techniques for soil survey at levels of medium and small scales are saving on time, labour and money. Most of field work can be done in the laboratory. The unit of mapping, the numbers of soil charts and the accuracy of the bounderies required by the certain scale were as good as the results obtained by the classical method. The soil interpretation was done in a comprehensive way. Utilization of optical and computer treatment for obtaining various useful imagery of MSS, the establishment of patterns of typical field region, and other data from geological references were very useful for the interpretation.
