Abstract: Desertification index system plays an important role in desertification research,as indicating both the level of dynamic mechanism of desertification and the contribution to the rehabilitaition of desertified land.Firstly,the problems concerning the selection,acquisition,quantification and checking about index are evaluated according to the criterion of standardization,simplicity and practicability.Then,the approach is made to the relationship between ecological base plane and indicators.Finally,based on the view that the establishment of ecological base plane is fundamental to ideal index system in the desertification monitoring and assessment,three principles to design index system are put foreward,which are respectively zonation,scale and landscape.

Key words: ecological base plane, zonation, scale, landscape
