摘要:
 随着城市环境与居民健康之间的关系越来越为人们关注，作为城市绿地系统重要组成成分之一的小型公园绿地日益被重视。引入分形理论的计算方法，用量化的方式探讨福州市主城区小型公园绿地的空间布局特征，以期为后续此类小型公园绿地的合理布局与科学选址提供参考。以福州市143个小型公园绿地为研究对象，通过网格维数、半径维数、边界维数3个分形维数的计算，分析总结其空间布局分形特征。结果表明，福州市主城区小型公园绿地空间布局具有分形特征但不明显，空间分布不均衡。其网格维数为1.135 3，空间分布均质度和填充度较低；半径维数达到2.608 0，离心程度强，没有明显的城市中心指向形态，布局密度以绿地重心为中心向四周逐渐增大的平均速度比较大，但实际上是一个由中心开始，先缓慢地增加，后转为不均匀的较快速增加，继而进入缓慢增加的动态变化过程；边界维数为1.385 9，生态稳定性一般，具有较为显著的边界效应。福州市主城区的小型公园绿地其空间布局仍可进一步优化，研究结果可为其空间布局合理性的提高与自我优化结构潜能的提升提供理论依据。
Abstract:
 As the relationship between the urban environment and the health of residents has attracted more and more attention,small parks and green spaces,which are important components of the urban green system,have been paid more and more attention.Fractal theory was introduced to discuss the spatial layout characteristics of small parks in the main urban area of Fuzhou City,in order to provide references for the rational layout and scientific location of small parks.Taking 143 small public urban green spaces in Fuzhou City as the research object,the fractal characteristics of the three fractal dimensions,including grid dimension,radius dimension and boundary dimension,were analyzed and summarized.The results indicated that the spatial layout of small parks in the main urban area of Fuzhou had fractal features but was not obvious,and the spatial distribution was uneven.The grid dimension was 1.135 3,and the spatial distribution uniformity and filling degree were low; the radius dimension reached 2.608 0,the degree of centrifugation was strong,and there was no obvious urban center-pointing form.Its layout density was expressed as the center of the green space.The average speed of increase was relatively large,but in fact it was a process that starts from the center,first slowly increased,then became uneven and quickly increased,and then entered a slowly increasing dynamic change process; The boundary dimension was 1.385 9,ecological stability was in general level.It had a more significant boundary effect.The small parks and green spaces in the main urban area of Fuzhou were able to be further optimized.In the follow up similar parks in the site selection and construction,attention should be paid to the rationality of its spatial layout,so that the potential of this self-optimizing structure can be further improved to better build a sustainable city.
