Aiming at the problem of tourism scenic route planning, this paper studies and analyzes the combined influence of terrain slope and surface properties on vehicle route planning. The “window moving method” is introduced to carry out early slope calculation and traffic ability analysis for the terrain, roughness evaluation index is established respectively for wheeled and tracked vehicles and the...

This study develops a new concept of economic slope. based on the concept of slope in physical environment. Then the concept is applied to analyze the landscape dynamics in Los Angeles County. It proposes that areas with higher economic slope are more dynamic and less stable than others due to the pressure from the surrounding areas. The hypothesis is tested through detailed studies of Los Ange...

The application of GIS to the forecast and evaluation in the regional landslide can provide scientific basis for the regional geological environment management and the geological disaster assessment, can integrate the scattered data to share each other, and can improve data value. Its powerful interface function library provides a good tool for the professional GIS design and development. This ...

BACKGROUND Natural populations of most organisms, especially unicellular microorganisms, are constantly exposed to harsh environmental factors which affect their growth. UV radiation is one of the most important physical parameters which influences yeast growth in nature. Here we used 46 natural strains of Saccharomyces cerevisiae isolated from several natural populations at the "Evolution Cany...

Vegetation indicators and spatial distribution characteristics are the core and basis to study the complex human-natural coupled system. In this paper, with Landsat 5 and Landsat 8 remote sensing data, we quantitatively estimated vegetation coverage in Henan Province, China. According to the urbanization rate, altitude, slope degree, and slope exposure, we analyzed spatial and temporal variatio...

The seabed of northern Norway was explored using video and multibeam surveys to assess the distribution of megafauna and examine associations of benthic organisms to their physical environment. The study area was initially divided into ten marine landscapes based on seabed morphology and general water mass distribution. In total 195 taxa were observed during video recordings. The highest number...

One of the spatial abilities that has recently revealed a remarkable variability in performance is that of using terrain slope to reorient. Previous studies have shown a very large disadvantage for females when the slope of the floor is the only information useful for encoding a goal location. However, the source of this sex difference is still unclear. The slope of the environment provides a d...

Slope failure like in the Hinlopen/Yermak Megaslide is one of the major geohazards in a changing Arctic environment. We analysed hydroacoustic and 2D high-resolution seismic data from the apparently intact continental slope immediately north of the Hinlopen/Yermak Megaslide for signs of past and future instabilities. Our new bathymetry and seismic data show clear evidence for incipient slope in...
