基于成本加权距离法的阜阳市综合性公园辐射研究

A Cost weighted distance-Based Research on the Radiation Effect of Urban Comprehensive Parks

研究以成本加权距离法为主要方法,并结合掩膜、栅格数据融合等技术考虑河流、铁路等障碍物的影响,反演阜阳市综合性公园辐射区。结果表明:阜阳市老城区公园辐射覆盖率高,新城区覆盖率低,颍东区辐射区相对孤立,城市综合性公园布局整体性差;辐射分值自老城区向外逐渐降低,城市综合性公园布局过于集中,老城区以外区域公园建设滞后;公园辐射区重叠区域大,一些公园实际效用不高。

based on the cost weighted distance method, combined with mask、Grid Data,this research is to consider the influence of the river, railway and other obstacles, and then invert Fuyang comprehensive park radial area. The results showed that old city park radial coverage is high and new urban coverage rate is low, radial area is relatively isolated in Yingdong District, urban comprehensive park layout integrity is poor; radiation score is gradually reduced that from the old city to outward, urban comprehensive park layout is too concentrated, regional park construction lags behind in the outside of old city; Park radial Area＇s overlap region is large, practical utility of some parks is not high.
