Grasslands play an important role in the terrestrial biogeochemical carbon (C) cycle and partly mitigate climate change through C occlusion within phytoliths. Grassland degradation has a significant influence on the coupled biogeochemical cycles of C and silicon in the Inner Mongolian steppe of China, but there are few reports about the impact of grassland degradation on phytolith C sequestration...
Purpose Heavy winter mulch treatments are commonly practiced in Phyllostachys praecox bamboo forests to increase bamboo shoot production in early spring in subtropical China. The aim of this study was to quantify the chemical behaviour of the mulching materials and the immediate response of soil carbon (C) to the heavy winter mulch treatments. Material and methods In the field study, in situ decomposition...
Based on the fuzzy random time-variant probabilistic model, research on the assessment methods for the reliability of existing reinforced concrete bridge is performed. Considering the time-dependent feature of the structural resistance for existing reinforced concrete bridges, probability models for assessment of the present resistance and time-dependent resistance model is given. The resistance degradation...
