| 摘 要： | 以哈尔滨市1989年、2007年2期Landsat TM遥感影像为主要数据源,在RS和GIS的支持下,分析土地利用格局的动态演变,并应用马尔可夫模型完成对研究区未来土地利用的定量预测。研究结果表明:林地、水域和草地发生了扩张,耕地、居民工矿用地和未利用地减少;耕地和林地具有较高的保留率,草地和未利用地具有较高的转换率;2007年以后土地利用变化的趋势是林地逐年增加,其它土地利用类型逐年减少,该变化持续到2079年后,区域土地利用达到相对稳定状态时,耕地占57.79%,林地占25.24%,草地占2.80%,水域占3.98%,居民工矿用地占9.28%,未利用土地占0.91%。

| Abstract: | The remote sensing images of 1989 and 2007 were used as the main data source for Harbin city.With the support of RS and GIS technologies,the dynamic change of land use pattern was analyzed.Markov model was used for the quantitative forecast of the future land use of the study region.The result showed that: the area of forest land,water region and grassland increased.The area of crop land,residential land,unused land decreased.The crop land and forest land had a high reserving rate and the grassland and unused land had a high conversion rate.The land use tendency after 2007 is that forest land has increased,year by year and other types of land use has decreased.This change will last a long time until it reaches a relatively stable state,which means that the percentage of cropland,forest land,grassland,water area,residential land and unused land is 57.79%,25.24%,2.8%,3.99%,9.38% and 0.94% respectively. |
