基于数量方法的德州市1996-2006年土地利用结构变化研究

以德州市1996-2006年土地利用变化调查数据为基础,对其土地利用结构变化过程进行了描述,并利用变化强度指数、相对变化率、土地利用动态度、区位熵等指标模型进行了区域土地利用时空变化分析.结果表明:(1)德州市耕地面积变化不大;(2)德州市城镇建设用地、交通用地和林地规模继续增大,未利用地面积减少较快;(3)德州市各县市土地利用结构差异明显.德州市土地利用变化的动力因素有自然、经济和社会3个方面,并相应地提出了土地合理利用建议.

Changes of Landuse Structure in Dezhou City from 1996 to 2006 Based on Quantitative Methods

Based on the data obtained from landuse change investigation in Dezhou City from 1996 to 2006,changes of landuse structure were described and spatiotemporal variations of regional landuse were analyzed by using the models of change intensity index,relative change rate,landuse dynamic degree and location entropy.Results showed that the change of cultivated land was not significant;scales of urban construction land,traffic land,and forest land were further increased;scale of unused land was reduced fast;and the difference of landuse structure in each county of Dezhou City was evident.Landuse changes in Dezhou city were driven by natural,economic and social factors.Finally,the causes of landuse structure changes were analyzed and some suggestions were put forward.
