基于遥感和GIS的五陵原土地利用动态变化研究

利用Landsat的TM和ETM＋数据,对五陵原1988、2005年的土地利用状况进行了监测,并利用土地利用类型动态度、土地利用程度和转移矩阵等指标定量分析了17年间土地利用的变化特征。结果显示,研究时段内耕地、林地、水体和未利用土地都有不同程度的减少,而建设用地和果园面积增幅较大。在过去17年间研究区土地利用动态度达到1.14%,土地利用程度偏高且有增加趋势,这说明研究区土地利用阶段仍处于发展期,土地利用方式受人为活动和经济发展特别是快速城市化和果业经济发展影响强烈。

Research on the Land Use Dynamics of Wulingyuan Based on RS and GIS Technology

By using the TM and ETM+ data of landsat images,the land use situation of Wulingyuan in 1988 and 2005 was monitored,and the variation features of the land use types during the 17 years were quantitatively analyzed by adopting the land use dynamics,land use degree and transfer matrix.As indicated by the results,the area of farmlands,woodlands,waters and unused lands in the study area all decreased to different degrees,but that of the construction lands and orchard saw a big increase.The land use dynamic degree of the study area reached 1.14% during the past 17 years,land use degree was a little high but still increasing,which indicated that the land use in the study area was till at its developing stage,and the land use patterns were greatly influenced by human activities,economic development and especially the rapid urbanization and development of fruit industry.
