The aim of this review is to acknowledge the interrelationship between topography and ice sheets in Antarctica that must have necessarily taken place during the last 34 million years. Several attempts have been made using numerical modelling
. In this review, the subglacial topography of Antarctica is inspected with reference to both contemporary ice-flow processes and ice-sheet history. Examples of how landscape evolution have been estimated are discussed, which provides a means by which
the continental scale link between topography and ice-sheet development can be investigated in future.

. The study brought attention to limited access to educational aids, lack of basic skills in cartography and topography resulting in inability to interpret the map content properly, and limited ability to compare the cartographic data with the corresponding

Relationships between vegetation and soil and topography in a dry warm river valley, SW China
The aim of this research was to propose a four-staged procedure by combining several multivariate statistical techniques to detect the relationships between vegetation and soil and topography, and thereby identify the key factors for the degraded
ecosystem restoration and management. Forty-three plots were selected for the field survey of the vegetation, soil and topography variables in the dry warm river valley of the upper Minjiang River, Sichuan Province, China. Cluster analysis demonstrated
