大连开发区土地利用空间格局演变机理研究

Research on Land Use Spatial Pattern Evolution Mechanism in Dalian Development Zone

以多时序土地利用、遥感数据为基础,通过GIS技术结合土地利用动态度、空间叠置与转置模型,分析了2003—2012年大连开发区土地利用空间格局演变机理。研究表明:①速率变化模式呈现各土地利用类型中草地减少的速度最快,交通运输用地增长的速度最快;②数量变化模式呈现出草地与园地面积大量减少,建设用地和交通运输用地增加,草地向建设用地转移的趋势;③空间格局演变趋势呈现建设用地沿交通干线和海岸线分布,由西部向东部扩展趋势。

Based on multi - temporal land use data and remote sensing data, through GIS technology and land use dynamic degree, spatial overlay analysis model, this paper analyzed the Dalian Development Zone＇s land use spatial pattern evolution from 2003 to 2012. The results showed that：（1） Rate change patterns showed that grass decreased rapidly and transportation land increasing rapidly;（2）Quantity change patterns showed a significant reduction in the grass and garden area, increased of construction land and transportation land, the grass had a trand to transfer into the construction land;（3） Spatial evolution trend pattern showed the construction land distributed along traffic lines and the coastline, presenting a trend of extending from west to east.
