The paper reviewed hydrogen production biotechnology on theoretical and scientific aspects in our lab. Fermentative process is better for hydrogen production than photosynthetic process. The fermentative process, ecology of the activated sludge system, bacteriology of anaerobes, engineering control, reactor design, and fundamental research have made a great progress. At present, the demonstration...
The Horqin Sandy Land is one of the most seriously desertified regions of China. In this paper, we measured the aboveground and belowground biomass, caloric value in biomass components, and biomass energy allocation at three distinct land-cover types of habitat along a desertification gradient in Horqin Sandy Land: non-desertification land (ND), light desertification land (LD), and severe desertification...
