    The objectives of this study were to evaluate the environmental and economic impacts of year-round-grazing systems and a conventional housing system for Japanese Brown fattening steers by the life cycle assessment (LCA) method. Four treatments were designed in this study; grazing fattening without feed rice (G group), grazing fattening with feed rice (GR-1 and GR-2 groups) and conventional housing fattening (H group). For the three grazing groups (G, GR-1, GR-2), supplemental concentrate was constantly supplied and hay was supplied only in winter.

    The recent increase in the number of tourists has raised serious concerns about grassland degradation by tourism activities in Inner Mongolia. Thus, we evaluated the effects of tourism activities on the vegetation and soil in Hulunbuir grassland. We identified all the plant species, measured the number and height of plants and plant coverage rate, calculated species diversity, and estimated above-ground biomass in the used plot and the non-use plot. We also examined soil hardness, and soil physical and chemical properties in both plots.
