Abstract:
      This paper states the competitive model of land-use analyzing the population increase and the change of land-use according to statistic data of Shandhuang experimental area from 1982to2004．The result showed that the policy factor is the principal part of responding to environment and has positive action to control the land-use．Technology factor can abate the competitive press of land—use the progress of technique can deeply influence the change of land-use and change the competitive mode of land-use．Traditional characteristic agriculture and special agriculture based on the technique progresses are the developmental direction of Loess Hilly-gully region．
