摘要
以河北省石家庄市为例,以2008年和2014年石家庄市Landsat TM影像为基础,对2008—2014年间石家庄市主要土地利用类型的变化幅度以及相互转化的关系进行分析,得到石家庄市土地利用类型转移矩阵,通过马尔可夫矩阵对石家庄市2020年的土地利用类型进行预测。分析结果表明,在2008—2014年间,石家庄市土地利用类型转变最大的为未利用地和居民工矿用地,增加的居民工矿用地主要由未利用地和农地转变而来,草地、林地和水域的变化相对不大。截至2020年,石家庄市土地利用类型中居民工矿用地、未利用地和农地这3类土地利用类型的面积非常接近,居民工矿用地成为在12年间增长幅度最大的类型,表明在此期间石家庄市城市化建设力度较大。
Taking Shijiazhuang city of Hebei Province as study case, on the base of Landsat TM remote sense image of 2008 and 2014, the transition matrix of Shijiazhuang City＇ s land use was developed through the analysis of the land use characteristics＇ change range and relationship with each other form 2008 to 2014, and the dynamic change trend of the land use in 2020 also forecasted by using markov matrix. The results showed that the residential land was mainly changed from unused land by 2020, and residential land has become the largest increase in area during twelve years, the Changes in grassland, woodland and waters were relatively small. By 2020, the area of Shijiazhuang City land - use types in residents industrial land, unused land and agricultural land are very close, and residents industrial land will become the largest type of growth rate in 12 years, which showed that during this period Shijiazhuang city construction force are larger.
