摘要
以兰州市中心城区为研究对象,应用核密度分析揭示公园绿地空间布局特征,并运用改进Ga2SFCA模型(高斯两步移动模型)评估不同类型公园的可达性。结果显示,中心城区公园绿地的可达性整体呈现出“北高南低、西高东低”的分布特点。各类公园的可达性大体上都表现“西高东低”的共同特点,因其类别、大小和服务范围的差异,各类公园绿地与人口需求的相适程度也各不相同。基于此结果,为兰州市公园绿地资源配置和存量绿地的质量提升提供建议。
Taking the central city of Lanzhou as the research object,the nuclear density analysis was applied to reveal the spatial layout characteristics of parks and green spaces,and the improved Ga2SFCA model was used to evaluate the accessibility of different types of parks.The results show that the accessibility of parks in the central urban area is characterized by the distribution of“high in the north and low in the south,high in the west and low in the east”.The accessibility of all types of parks generally shows the common characteristic of“high in the west and low in the east”,and the degree of compatibility between various types of parks and the needs of the population varies due to the differences in their categories,sizes and service scopes.Based on the results,recommendations are provided for the allocation of park green space resources and the improvement of the quality of the stock of green space in Lanzhou.
