摘　　要：城市绿地景观格局研究在城市发展规划中的作用越来越重要,应用RS技术和GIS技术开展景观格局分析也正成为当前的主要趋势。以济南市建成区城市绿地为研究对象,分析了济南市城市绿地发展的历程与驱动因素、城市绿地的斑块特征,并针对以往景观格局分析大多仅注重数量分析的局限性,选取景观多样性指数、均匀度指数、优势度指数、破碎度指数、分离度指数、正方像元指数等景观格局指数,采用空间可视化技术从空间角度分析绿地系统的结构组成和空间配置特征,实现了济南市建成区城市绿地的景观格局综合空间评价与分级,力求为城市绿地系统建设与管理的科学决策提供参考依据。Study on landscape pattern of city green space is becoming more and more important in city development planning,taking advantage of RS technology and GIS technology to carry out the analysis of landscape pattern also is becoming the main trend currently.In this paper,we took urban green space of Ji′nan built-up area as the research site,and analyzed the development process and driving factors of Ji′nan green space,investigated and analyzed the general characteristics of green land patches,and according to the limitation that the previous analysis of landscape pattern mostly paid attention to quantity analysis,we selected landscape diversity index,evenness index,dominance index,fragmentation index,separation index,affirmative pixel index,etc.From the perspective of space,we analyzed the composition of structure,and spatial configuration characteristics of green space system by using spatial visualization technology.From the perspective of space,we achieved a comprehensive spatial evaluation and classification of landscape pattern of Ji′nan built-up area′s green space,striving to provide reference basis for scientific decision for the construction and management of city green space system.
