Title: Study of soil physical properties and community characteristics of different abandoned lands in Ziwuling area of Loess Plateau
Abstract: The evolution of environments and plant community characteristics in different abandoned lands were analyzed after abandonment for 4, 9,15 and 20 a,and the plant community characteristics,bulk density,water content and biomass of the different abandoned lands were also researched in the course of succession in hilly-gully regions in north Ziwuling of Loess Plateau.Results showed that in the progress of slow succession,plant species were distributed equally in weed community and the number of species and individuals was increased prominently;dominant and sub-dominant species belonged to 9 genera and 6 families.The distribution of root systems was increased in soil and soil configuration got loosen.As a result,the bulk density was decreased in certain depth.Soil moisture was ordered from large to small: 4 a,20 a,15 a,9 a and 20 a,4 a,5 a,9 a abandoned lands in 0-80 cm and 80-300 cm depth soil respectively.Above-ground biomass was increased with abandoned time,but the trend was slow.
