| 尝试使用位置大数据，基于使用强度、生态敏感度
(SE)与景观安全格局(LSP)指标对福州市晋安区城市公园生
态功能现状进行分析，探讨空间维度上的公园使用强度差异对
城市公园生态功能造成影响的原因。研究表明：1)不同空间
维度的使用强度对城市公园生态功能的影响，生态敏感度大于
景观安全格局；2)生态敏感度与使用强度存在显著相关性，
其中坡向、高程、土地利用类型与使用强度存在显著正向相关
性，在景观安全格局分析中，视觉安全格局、雨洪安全格局与
使用强度存在部分相关性；3)使用强度分析能够客观呈现游
客在空间维度上的人群密度变化，从而探究在不同空间维度
上，使用强度对城市公园生态功能空间变化产生的影响及原
因，并提供具有针对性的城市公园生态功能优化建议。 |

| Abstract: |
| By using location big data, this paper studied the present
situation of the urban parks' ecological functions in Jin'an District,
Fuzhou, based on the utilization intensity, ecological sensitivity
and landscape security pattern. The paper discussed the reasons
for the impact of park utilization strength differences in the spatial
dimension on park ecological functions. The results show: 1) The
impact of the intensity of use on different spatial dimensions on the
ecological sensitivity of urban parks is greater than the landscape
security pattern; 2) There is a significant correlation between
ecological sensitivity and utilization strength. Slope direction,
elevation, land use pattern and utilization strength significantly
correlate especially. In the analysis of landscape security pattern,
visual security pattern, storm flood security pattern and use intensity
are partially correlated; 3) Utilization intensity can objectively
show the changes of crowd density in spatial dimensions. So as to
explore, in different spatial dimensions, the influence of utilization
intensity on the spatial changes of urban park ecological functions
and its reasons. It can propose pertinent optimization suggestion to
improve ecological function of urban parks. |
