The Pattern and Optimization of Urban Ecological Recreation Space in Shanghai
通过缓冲区空间分析，研究了上海生态游憩空间的服务半径和覆盖特征，发现服务覆盖低且分布不均，并提出了市中心立体化、郊区均匀渗透等优化对策。
By using buffer spatial analysis method, based on the analysis of investigation and analysis of the main residential users, regional differences of service suitability of ecological recreation space is reflected through the service radius and the service coverage and the characteristics of the ecological recreation space pattern in Shanghai are revealed. It is found that spatial pattern of the low level of service coverage and uneven distribution impacted on the suitability of the public demand and resulted in a lower-level service function of Shanghai ecological recreation space. Some countermeasures are put forward. Firstly, spatial integration depth of ecological recreation space in downtown area should be three-dimensional. Secondly, the optimization in suburban should focus on uniform and permeability of space layout. At the same time, more attention should be paid to strengthening the function of corridor system of ecological recreation. Lastly, construction of ecological recreation space should be more natural and soft.
