Based on an actual corrugated steel plate arch bridge, considering soil-structure interaction, by using the finite element program of ANSYS, a 2-D finite element model was set up to analyze the soil pressure and structural deformation under different load conditions in detail. Since this type of structure relies on the soil-structure interaction to share the load, as the structural parameters h...

bility arises mainly from the limitations of the discrete data model and from the polygon-based mapping pracA geographical information system (GIS) or expert knowledgetice employed in conventional soil surveys. based fuzzy soil inference scheme (soil-land inference model, SoLIM) is described. The scheme consists of three major components: (i) a Zhu (1997a,b), Zhu and Band (1994), Zhu et al. mod...

GUO HC, WANG WB, LUO XH & WU XP. 2015. Characteristics of rhizosphere and bulk soil microbial communities in rubber plantations in Hainan Island, China. Phospholipid fatty acid analysis was used to investigate spatial variations in microbial communities of rhizosphere and bulk soil in rubber plantations in Hainan Island. Rhizosphere and bulk soil were collected from immature and mature rubber t...

Soil is a living system and has to be managed as such in agriculture to improve sustainability. Soil health refers to the biological, chemical and physical features of soil that are essential to long-term sustainable agricultural productivity with minimal environmental impact. Thus, soil health provides a overall picture of soil functionality. Soil provides the habitats for a wide range of livi...

The response of soil properties to vegetation types is still not well understood and the relationship between vegetation types and soil properties has not been quantified in highland grasslands. A field experiment was conducted in highland grassland of the Loess Plateau in China to study the distribution of soil properties under different vegetation. 22 plant communities totaling 17 species tha...

Urban grasslands not only provide a recreational venue for urban residents, but also sequester organic carbon in vegetation and soils through photosynthesis, and release carbon dioxide through respiration, which largely contribute to carbon storage and fluxes at regional and global scales. We investigated organic carbon and nitrogen pools in subtropical turfs and found that dissolved organic ca...

Long-term investigations of soil moisture at different precipitation patterns in the black soil in Hailun county, Northeast China were made. This area is an important base for marketable grains production due to a short cultivation history, high soil organic matter content, and high yield potential. In this region, precipitation is the principal water source during the cropping season, hence so...

Rubber is a polymer of isoprene, consisting mainly of cis-1,4-polyisoprene units. The unmanageable production and its irresponsible disposal pose severe threats to environmental ecology. Therefore, the current study focuses extensively on the ill-effects of Rubber disposal on soil microbial functional diversity as it reflects the health of ecosystem by acting as a key component in ecosystem pro...

The contents of this publication are the sole responsibility of ECRAN and can in no way be taken to reflect the views of the European Union. Executive summary • Soil degradation, including soil erosion, land desertification, soil salinisation, soil impoverishment and soil pollution, has become more and more serious in...

Soil erosion rates and soil quality indicators were measured along two hillslope transects in the Loess Plateau near Yan'an, China. The objectives were to: (a) quantify spatial patterns and controlling processes of soil redistribution due to water and tillage erosion, and (b) correlate soil quality parameters with soil redistribution along the hillslope transects for different land use manageme...
