摘要/Abstract

摘要： 城市森林景观生态格局研究不仅是城市森林系统规划与城市生态建设的基础和前提,而且是优化城市空间结构、充分发挥城市森林生态功能以及创建生态宜居环境的重要途径和手段.本研究以RS和GIS技术为支撑,通过总体景观生态格局定量分析和梯度分析等研究方法,采用10个景观指数从斑块水平和景观水平两方面,对济南市建成区城市森林景观生态格局进行定量分析,并提出优化对策.结果表明: 济南市建成区城市森林覆盖率为15.8%;城市森林总体景观生态格局在景观水平上表现为城市森林景观斑块类型较齐全、景观破碎化程度较大、各类型城市森林所占面积存在差异、以大斑块为主且同种斑块高度连接,在斑块类型水平上表现为生态公益林以大斑块为主且占优势地位、风景游憩林形状较规则且以大中型斑块为主、道路林及附属林形状复杂且以小斑块为主、生产经营林缺乏;在斑块类型水平上,以风景游憩林为主导类型、生态公益林斑块面积最大、道路林及附属林破碎度大,在景观水平上,城市中心森林景观破碎度大、人为干扰严重、景观形状复杂;在城市森林景观生态格局分析基础上,提出“一环二网、三片四轴、多点棋布”的济南市城市森林生态网络构建方案,从而加强各类型城市森林的连接度,发挥大尺度生态系统的整体生态效益.

Abstract: The ecological pattern research on urban forest landscape is the foundation and premise of urban forest system planning and urban ecological construction, as well as an important way of optimizing urban spatial structure, giving full play to urban forest ecological function and creating ecological and livable environment. Ecological pattern of urban forest landscape in built-up area of Ji’nan city was quantitatively analyzed and the corresponding optimization countermeasures were put forward through quantitative analysis and gradient analysis of the overall landscape ecological pattern by RS and GIS technology with 10 landscape indices at patch level and landscape level. The results showed that urban forest coverage rate in built-up areas was 15.8%. At the landscape level, the overall landscape ecological pattern of urban forest showed following patterns: relatively complete types of urban forest landscape patches, greater degree of landscape fragmentation, different area of various types of urban forest, large major patches, and highly connected same patch types. At the level of patch type, the ecological public welfare forest was dominated by large patches. The shape of scenic recreational forest was regular and dominated by large and medium patches. The shape of road forest and subsidiary forest was complex and dominated by small patches. The production and management forest was lacking. At the level of patch type, landscape recreational forest was the dominant type, ecological public welfare forest patch area was the largest, road forest and ancillary forest fragmentation was large. At the level of landscape, urban central forest landscape fragmentation was large, human interference was serious, and landscape shape was complex. Based on the analysis of the ecological pattern of urban forest landscape, we proposed the construction scheme of Ji’nan urban forest ecological network, which was “one ring, two networks, three four axes, and multi-point chessboard”. Such scheme would help strengthen the connectivity of various types of urban forests and exert overall ecological benefits of large-scale ecosystems.
