摘要
根据丘陵型城市的特点,采用GIS中的网络分析模块对马鞍山市中心城区的综合性公园可达性进行分析,结合LA模型在可达性覆盖失衡的区域筛选出适宜的综合性公园选址地点。结果表明:马鞍山中心城区综合性公园分布不均匀,服务覆盖范围存在很大盲区;中心城区东南方向的可达性缺失现象最明显,西北方向及东侧均有不同程度的可达性缺失的情况;经由LA模型运算后,最后留存的6个能够满足周边居民点25 min内步行到达的要求,且有建设综合性公园条件的地块。采用网络空间分析法以模拟现实交通环境为主要手段对公园可达性分布进行数字量化,清晰地展现综合性公园实际可达性的分布状况,根据可达性分析结果,结合LA模型的演算使得公园选址有一定的科学依据。
The suitable location of comprehensive park was selected in the accessibility imbalance area. Com- bined with LA model, the network analysis module of GIS was applied to analyze the accessibility of comprehensive parks in downtown Maanshan based on the characteristics of hilly cities. The results indicated that the distribution of comprehensive park in downtown Maanshan was uneven, dead zone existed in the service coverage; The accessibili- ty deficiency in the southeast of downtown was the most obvious, varying degrees of accessibility deficiency ap- peared in the northwest and east of the downtown; Six regions met the requirements of arriving the comprehensive park within 25 min on foot, and the conditions was reasonable for comprehensive park construction; Quantifying the comprehensive park accessibility by spatial network analysis with the simulation of actual traffic environment, the distribution of actual accessibility of the comprehensive park was clearly demonstrated. Combined with the LA mod- el, the park location has a certain basis in the light of the findings of accessibility analysis.
