沈阳城市公园游憩压力

Recreational pressure of urban parks in Shenyang

在GIS支持下,结合距离衰减模型和Voronoi图估算了沈阳城市公园的游憩压力。结果表明:沈阳城市公园总游憩压力城郊差异不明显,西北区游憩压力大于东南区,以中山公园、新华公园、劳动公园、市府广场和万柳塘公园最高;城市公园单位面积游憩压力城郊差异明显,以新华公园、市府广场、八一公园、沈海园和枫露公园最高。距离衰减模型和Voronoi图相结合能克服单一使用距离衰减模型或Voronoi图的弊端,是城市公园游憩干扰强度鉴别的有效方法;研究获得了沈阳城市公园的相对游憩压力大小资料,为其优化建设和管护决策的制定提供参考。

Supported by GIS, the recreational pressure of urban parks in Shenyang was studied by using distance decay model combined with Voronoi graph. The results showed that the total recreational pressure of urban parks in Shenyang did not display obvious difference between downtown and suburban area, but the total recreational pressure of urban parks in the northwestern part of the city was higher than that in its southeastern part. Zhongshan Park, Xinhua Park, Laodong Park, Shifu Square, and Wanliutang Park suffered from the highest total recreational pressure, while Xinhua Park, Shifu Square, Bayi Park, Shenhai Park, and Fenglu Park suffered more urban park area-weighted recreational pressure. An obvious difference in area-weighted recreational pressure was observed between the parks in downtown and suburban area. The combination of distance decay model and Voronoi graph could overcome the shortcomings of distance decay model or Voronoi graph alone, being able to effectively measure the intensity of the recreational disturbances of urban parks, and to evaluate the service pressure of other urban service facilities. The related information acquired in this study could provide references for optimizing the spatial distribution of urban parks in Shenyang and making effective management plans for the urban parks in the City.
