摘要
景观生态格局模式强调景观空间格局对过程的控制和影响,并通过格局的改变来维持景观功能流的健康与安全。景观生态格局的研究方法有静态分析法和动态分析法。利用生态安全格局方法去建立整体性的生态基础设施是城市生态环境规划的基础,它为建设生态城市提供了理论基础和实践方法,可应用于分析城市的景观生态基本特征、城市的景观安全格局现状,规划城市景观生态格局。该研究以西安市为例,采用景观格局指数静态分析法分析了西安的生态环境及景观生态格局构成,归纳出西安市生态基质、廊道和斑块的分布及其特点,并就其中存在的基质形态破碎化、廊道人工化、建成区内斑块分散化问题进行了总结,以期为今后的西安市生态格局研究和完善提供理论基础。
Landscape ecological pattern mode emphasized the control and influence of landscape space pattern on process,and through change of pattern,it could preserve health and safety of landscape function flow.The study methods of landscape ecological pattern included static analysis method and dynamic analysis.Establishing integrated ecological infrastructure by utilizing ecological security pattern methods was the basis for urban ecological environment planning,which provided theoretical foundation and practicable means for ecological city construction,and which could be applied in analysis of basic characteristics of urban landscape ecology and current status of urban landscape security pattern,and in planning of urban landscape ecological pattern.By taking Xi＇an City for example,it could analyze ecological environment and composition of landscape ecological pattern in Xi＇an by adopting static analysis.It had concluded distribution and features of ecological bases,corridors and patches in Xi＇an.Meanwhile,it had made a summarization of fragmentation of base pattern,artificialization of corridors,and decentralization of patches at built up area,hoping to provide theoretical basis for researches and completion of ecological pattern in Xi＇an City.
