健康生态系统服务视角下的公园游憩和降温服务权衡关系研究--基于GWR量化分析

Study on the Trade-off between Recreation and Cooling Services in Parks from the Perspective of Healthy Ecosystem Services--Quantitative Analysis Based on GWR

城市公园绿地在改善人类福祉和调节气候等方面都起着重要的作用,而游憩服务对于城市居民的心理和身体健康尤为重要,同时也为城市公园绿地的发展指出了新的方向。然而,很少有研究关注游憩服务与城市绿色公园降温效果之间的权衡关系。本文从健康生态系统服务角度出发,以北京市中心城区公园为例,选取休闲游憩服务和绿地降温服务等功能指标,采用地理加权回归(GWR)计算,使用PPF曲线方法进行评估,通过计算和评估休闲游憩服务和降温服务两者的权衡关系,提出基于生态系统服务权衡的公园优化,以期为公园绿地的后期建设和布局优化提供一种新思路,并为其他资源型城市绿地空间系统规划提供参考。

The green space of the urban park plays a critical role in improving human well-being and regulating climate,and recreation services are particularly important in promoting urban residents’physical activities and mental health,meanwhile,it also points out a new direction for the development of urban parks.However,few studies have paid attention to the trade-off between recreation services and the cooling effect of urban green space.From the perspective of healthy ecosystem services,this paper takes the parks in the central city of Beijing as an example,selects two functional indicators,namely the recreation service and green space cooling service indicators,and calculates with the Geographically Weighted Regression(GWR)and evaluates with Production Possibility Frontier(PPF)curve method.By calculating and evaluating the trade-off relationship between recreation services and cooling service,the optimization design based on ecosystem service trade-off is proposed,which provides a new method for the later construction and layout optimization of park green space and the planning of urban green space systems in other resource-based cities.
