摘要: 根据2006年8月QuickBird卫星影像数据,利用GIS 技术和景观格局分析软件FRAGSTATS,分别从斑块组成、类型水平与景观水平分析了沈阳城市绿地景观格局。结果表明:沈阳三环内绿地斑块18 261个,绿地面积173.71 km2;斑块数目主要以中型斑块为主,占总数的62.25%,面积上以大型斑块为主,占总面积的85.59%;绿地总体呈现绿地斑块分布不均衡,绿地结构不合理。农业用地占面积最大,斑块聚集程度最高;居住绿地与附属绿地破碎化程度高,分布分散;整体景观多样性指数适中,为1.6,斑块类型丰富,均匀度较高,达0.73,蔓延度指数较高为0.83,存在着少数类型控制整个景观的现象。建议调整城市绿地空间布局与结构,提高中小型绿地斑块如居住绿地在城市绿地景观中的比重。

Abstract: Based on the QuickBird image in August 2006, and by using GIS technique and spatial pattern analysis software FRAGSTATS, this paper analyzed the urban green space landscape pattern of Shenyang City at patch composition, class level, and landscape level. The results showed that within the 3rd ring road of the City, there were 18 261 patches of green space, covering an area of 173.71 km2. 62.25% of the patches were mediumsized, and 85.59% of the total area was made up of large patches. The distribution of urban green space was not uniform, and the structure was not reasonable. Farmland had the largest patch area and the highest assembly degree, while residential green space and attached green space were highly fragmented and distributed separately. The landscape Shannon’s diversity index was at intermediate level (1.6), patch types were rich and landscape Shannon’s evennessindex was high (0.73), and contagion index was 0.83. There existed a phenomenon that fewer green space landscapes controlled the whole green space pattern. It was suggested that in Shenyang City, the structure and distribution of urban green space should be adjusted, and the proportion of medium-sized patches such as residential green space should be increased.
