土地利用视角下的景观要素空间关系分析——以厦门市为例

Spatial Relations of Landscape Elements From the Perspective of Land Use——A Case Study of Xiamen

提出了基于矢量数据和拓扑关系的景观要素空间关系研究方法,介绍了应用GIS技术计算景观要素空间联系度指数和空间关联度指数的方法,并以厦门市为例,从土地利用视角对景观要素空间关系及其变化进行分析。研究结果表明,期间厦门市景观要素存在明显分异的空间关联格局且总体趋向交错分散,反映了区域城市发展和地域开发的基本格局,特别是围绕建设用地扩张和农田变更的空间邻接特征变化,揭示了人类活动对区域土地利用格局变化的控制作用。

The study method of spatial relations of landscape elements based on vector data and topological relations is proposed. The ways to calculate spatial contact degree index and spatial correlation degree index of landscape elements using GIS technology are described. Take Xiamen for example,spatial relations of landscape elements and their changes are analyzed from the perspective of land use. The study result shows that there are obvious differentiation and staggered dispersion trend generally in spatial association patterns of landscape elements in Xiamen during the period. It reflects the basic pattern of urban development and regional development.Especially,the variation of spatial adjacent features around construction land expansion and agricultural land change reveals the action that human activities control landscape pattern change of regional land use.
