The trail is a pedestrian road connecting various landscape points in the park. It not only has directional and traffic functions, but also is the most effective means for the organization of the whole park. Taking Yaohu Country Forest Park in Nanchang City as an example, this study analyzed and discussed the design of trails and landscapes.展开更多

为了研究首都功能核心区新建小型城市森林公园缓解城市热岛效应的能力,以广阳谷城市森林公园为研究对象,基于遥感(remote sensing,RS)和地理信息系统(geographic information system,GIS)完成了2014年、2017年和2019年公园内及周边区域...为了研究首都功能核心区新建小型城市森林公园缓解城市热岛效应的能力,以广阳谷城市森林公园为研究对象,基于遥感(remote sensing,RS)和地理信息系统(geographic information system,GIS)完成了2014年、2017年和2019年公园内及周边区域的地表温度反演,同时结合长期定点监测公园内外空气温湿度,分析城市森林公园内及周边冷岛效应。结果发现:广阳谷城市森林公园建成后,在园外100 m范围内有一定的降温效果。相比建成前,2017年和2019年其100 m缓冲区内热岛区域占比分别减少了4.83%和1.38%,地表平均温度比核心区分别降低了0.72℃和1.15℃,说明公园建成以来,充分发挥了冷岛作用;公园内各测点在10:00—17:00的平均温度低于对照点1.65℃,公园内部的相对湿度比对照点高2.68%;3—8月公园内各点的平均温度比对照点低0.67℃,在3月、4月、6月和7月公园内各点的平均湿度比对照点高1.82%,说明森林公园在此段时间发挥着降温增湿的作用。展开更多

文摘Urban forest parks are open parks based on natural countryside, which can be used for outdoor sports, leisure and recreation, popular science education and other activities. The trail is a pedestrian road connecting various landscape points in the park. It not only has directional and traffic functions, but also is the most effective means for the organization of the whole park. Taking Yaohu Country Forest Park in Nanchang City as an example, this study analyzed and discussed the design of trails and landscapes.
