| 摘 要： | 沙漠化土地的等级划分问题是防沙治沙工程规划设计中迫切需要解决的问题。在已有的研究工作及利用遥感技术对我国主要沙漠化地区的地表特征进行系统分析的基础上,以风沙地貌作为主导指征,植被和土壤作为辅助指征,依据它们所反映出的阶段性特征,制定了沙漠化土地等级划分方案。

| Abstract: | It is necessary and urgent for planning and designing the peoject of proventing and controlling desertification to resolve the problem of grading sandy-desertified land. On the basis of previous researches, authors have systematically analysed the ground features of main sandy-desertified regions in China with remote sensing techniques.The scheme of grading sandy-desertified land has been established according to the phased features during formation and development of sandy desertified land, which takes aeolian landforms as principal indicator and vegetation and soil as assistant indicators. |
