- 摘要:
- 利用QuickBird高分辨率卫星影像图并结合GIS软件，运用景观生态学的原理和方法，分析了宁德市区公园绿地的景观结构和格局。结果表明：宁德市城市公园绿地斑块的形状指数较小，均低于2.5。从不同公园景观类型的破碎度来看，市区级公园景观破碎化最低，仅为0.006 80，而专类公园、街旁公园斑块破碎化程度处于相对较高水平。各类公园绿地景观的分维数普遍较低，均小于1.25，斑块形状相对规则，绿地景观斑块边界较为简单。这种布局不利于维护城市生物多样性，同时也不利于营造自然化绿地景观。所以，今后宁德市在公园绿地建设中，应重点加大社区公园、街旁绿地公园绿地建设力度，提高广场、社区公园、街旁绿地和带状公园的比例，力求各类斑块配置合理，满足当地居民生活休闲需求和绿地生态功能需求。
- Abstract:
- Applying the landscape ecological principle and method, using the high-resolution data of QuickBird satellite remote sensing image and GIS, the paper analyzed the public park landscape structure and pattern in Ningde city. The results show that patch shape index of the park green of Ningde city is smaller than 2.5. From the fragmentation of different types of park, the fragmentation of urban park is the lowest, only 0.006 80, but the fragmentation of the category park, matine park is the relative high level.The fragment index of each kind of park landscape is generally lower than 1.25. Patch is relative rules and green landscape patch border are relative simple. This kind of layout is disadvantage to defending the city biodiversity, simultaneously is also disadvantage to building the nature green landscape.So constructing the park in Ningde in the future, which the key should enlarge nearby the community park, the street green dynamics, enhances nearby the square, the community park, the street green and the belt-shaped park proportion, makes disposition of every kind of patch to be reasonable,satisfies the leisure needs of local residents living and ecological functions of green space requirements.
