摘要:以南昌市城市森林景观为研究对象,运用GIS技术对城市景观空间格局进行了定量分析。结果表明:研究区城市森林景观斑块平均面积与斑块尺度的标准差最大,而斑块分维指数较小,反映了城市森林景观斑块的基本特征;研究区景观类型齐全,但空间分布不均,老城区景观相对集中,多样性指数和均匀性指数相对较低。提出了城市森林生态网络规划建设的若干对策,如南引北堵、三环八枝、中心城区带、环城、楔城、廊道、园林等,注重滨江、湖泊林带建设,大力发展垂直绿化和屋顶绿化。

Abstract:Taking Nanchang urban forest landscape as the research object, the spatial pattern of urban landscape is analyzed quantitatively by GIS technology. The results show that the standard deviation of the average area and patch scale of urban forest is the largest among all the urban landscape patches in the study area, while the patch fractal dimension index is small, which reflects the basic characteristics of the urban forest landscape patches; the study area has a complete range of landscape types, but the spatial distribution is uneven, the old urban landscape is relatively more concentrated, and the diversity index and evenness index are relatively low. This paper puts forward some countermeasures for the planning and construction of urban forest ecological network, such as South leading to North blocking, three rings and eight shoots, central urban belt, ring, wedge, corridor, garden, etc., paying attention to the construction of riverside and lake forest belt, vigorously developing vertical greening and roof greening.
