In China’s Loess Plateau severe gully erosion (LPGE) region, the shoulder-line is most intuitive and unique manifestation of loess landform, which divides a landform into positive negative terrains (PNTs). The spatial combination model PNTs great significance for revealing evolution landform. This study modeled proposed Surface Nibble Degree (SND), new index that reflects comparison areas PNTs....

The origin of large areas dominated by pristine open vegetation that is in sharp contrast with surrounding dense forest within the Amazonian lowland has generally been related to past arid climates, but this is still an issue open for debate. In this paper, we characterize a large open vegetation patch over a residual megafan located in the northern Amazonia. The main goal was to investigate th...

In this article we propose a Decision Support System using Case Based Reasoning (CBR) Technique for assessing ground water potential. Ground water is found in bedrock or in thick masses of overburden many feet below the surface. Theoretically ground water is function of various terrain parameters viz. Land Use/ Land Cover, Geology, Soil, Landform and Lineament. Using this theoretical framework ...

In order to explore the spatial distribution pattern and natural causes of sandy desertification land in Ali area, on basis clarifying dynamic change laws areas, degree pattern, main controlling factors are analyzed from three aspects landform, climate vegetation. During 22 years 1992 2014, area shows a law first increase then decrease, reaching peak 61,054.14 km2 2004, accounting for 20.57%, d...
