And also calculate the converting probability matrix basing on the results of LUCC has been classified. It predicts the area and probability of MiQuan's LUCC in the future by model of Marlkov.According to the research, It has taken a great change in heavy salt land of Lucc forest land, the former increases 19051hm2,, and the latter decrease 15943hm2, grassland increase 34641hm2,desert increase 4616hm2, fields decrease 6241hm2.
