基于GIS与RS支持下的城市生态景观格局优化研究——以小福州为例

Landscape Pattern Optimization Based on RS and GIS in Fuzhou

城市景观结构与功能、格局和过程之间的联系是当今人们关注的主题之一.本文选择福州市(小福州)为研究区域,应用RS与GIS技术对2003年、2007年、2009年三期遥感影像进行解译判读,并且利用景观分析软件深入分析了研究区景观格局时空变化.研究表明城市扩展造成了生态绿地破碎化、景观连通性降低及景观单一等问题.同时结合景观组分的生态系统服务功能和空间作用关系,研究了福州市景观结构紧密性和生态功能空间差异,进而构建源地、生态廊道和生态节点等景观组分模型,以便实现区域生态网络的空间联系.最后本研究对区域景观格局优化提出参考方案.

The link between urban landscape structure and function, pattern and process is one of the themes of today＇s attention. Fuzhou is chosen as a study area , and application RS and GIS technology for 2003 years, 2007 years, and 2009 years of remote sensing image interpretation phase combined with landscape analysis software in-depth analysis of the research area landscape pattern changes of time. Studies have shown that urban expansion resulting in fragmentation of the ecological green space, reduce landscape connectivity and landscape single issues. Combined with landscape components the value of ecosystem services and the role of spatial relationships, landscape structure, Fuzhou, closely studied the ecological functions and spatial differences. Then build sources, ecological corridors and landscape ecological components of the node model, in order to achieve regional ecological network of spatial relations. Finally, this study made reference to the regional landscape pattern optimization program.
