| 摘 要： | 利用1994和2003年2期TM/ETM+影像,获得徐州市区土地利用现状图,据此计算出1994～2003年徐州市区各土地利用类型的年变化率指数和转移矩阵,并运用马尔可夫模型对该区土地利用变化进行研究.结果表明,在1994～2003年徐州市区土地利用变化明显,其中建设用地和未利用地变化较大,城市绿地和农业用地变化次之,水体的变化则不明显.预测在未来18年间,建设用地持续增加,农业用地进一步减少,城市绿地增长缓慢.

| Abstract: | Based on the satellite remote sensing TM/ETM images,maps of rural land use in Xuzhou city from1994 to 2003 were obtained.Annual change rate indexes and transfer matrix of land use types were calculated.Dynamic changes of land use in the city were forecasted based on Markov model.Then,the characteristics of land use from 1994 to 2003 were discussed.The changes of construction land and unused land were significant;changes of green land and cropland ranked second;but there were no significant changes in water body.In the following 18 years,construction land would constantly increase and cropland would further decrease.Meanwhile,green land would increase at a low speed. |
