Abstract: Characteristics of N input,output and translocation are studied using system analysis for an ecological household farm suffering severe sand erosion.Taking advantages of topographic gathering of nutrients and selecting low-flat land to establish"little oasis"using intensively cultivated crops and high-yield forage woods is demenstrated as a break through for the agricultural development of these regions. The steady support from farming,grassland grazing in summer and enclosed breeding with dry fodder of weed and tree leaves are the three guaranties for the success of animal husbandry characterized by Tan sheep.

Key words: temperate forest soil, elevated CO2 concentration, methane, methanotrophs
