摘　　要：以侯马市为例,在RS和GIS技术的支持下,定量分析了侯马市景观格局的空间分异特征。结果表明,景观指数能够很好地反映研究区各缓冲区景观格局的变化特征;利用做缓冲区的方法提取样带在分析北方平原城市圈层景观格局的梯度变化上有一定的优势。该项研究对于合理引导城市扩张,以便减小由于城市扩张所引起的当地生态退化问题具有一定的实践意义和理论参考价值。With the support of RS and GIS technology,this paper aims to analyze spatial distribution characteristics of the landscape patterns of Houma City as a case study.The results show that the landscape index can well reflect the changing characteristics of landscape patterns of each buffer zone in the study area.The method of making the buffer zone to extract samples has certain advantages in the analysis of gradient change on circle landscape patterns in plain cities of northern China.This study has certain significance and theoretical reference value for reasonably guiding urban expansion and reducing local ecological degradation caused by urban expansion.
