從全球暖化到臺灣的極端氣候及都市熱島效應（Urban Heat Island），都市環境氣候溫越來越熱且越來越難降溫；極端氣候使環境變化，讓春季、秋季舒適氣候感覺縮短，「高溫季節」影響時間越來越來長，溫度也越來越熱，形成了「都市高溫熱環境」，都市熱環境直接影響都市民眾、戶外工作者、貧窮者、老人及小孩等；現今的能源電價皆已高漲，有些民眾為了節省電費，不使用空調系統降溫，造成很多民眾因為高溫帶來直接的熱傷害，使健康受損。日均溫高達攝氏33度，使65歲以上老長者如果死亡率甚至比平常多出了15％嚴重者甚至喪命，都市戶外溫度也年年攀升，甚至高溫有時已超過人體正常溫度37°C(台灣公共衛生雜誌，2011)。
臺灣的國家森林遊樂區處於森林覆蓋環境中，分佈於全臺北、中、南、東各區，森林遊樂區的海拔分佈由150~3,880m不等，每座國家森林遊樂區各有不同屬性與特殊自然環境景觀，森林遊樂區除了可以體驗自然環境及環境芬多精等，森林環境舒適環境更可以讓都市民眾在「高溫季節」遠離都市熱環境。
臺灣森林覆蓋率為60.7%，林業署第四次森林資源調查報告數值呈現，是全球平均值30.3%的2倍之高；農業部林業署自1965年起，開始進行全臺灣國家森林遊樂區之規劃與建設，目前設置遊樂區共計19處，2021年在提供超過400萬人次之遊憩(交通部觀光署，2021)。
本論文將分析探討在都市熱環境季節，透過旅遊方式造訪國家森林遊樂區，避開都市熱環境所造成人體生理上的熱不適，透過旅遊造訪國家森林遊樂區的環境舒適而得到緩解；研究範圍由北、中、南、東分區的國家森林遊樂區及分區都市進行分析溫度差距，進而分析國家森林遊樂區與都市的距離及降溫效益，在「高溫季節」來臨時，提供降溫效益資訊讓民眾可以得到降溫指引。

From global warming to Taiwan's extreme climate and the Urban Heat Island effect, the urban environment is getting hotter and harder to cool down. Extreme climate changes the environment, shortening the comfortable climate in spring and autumn. " The impact of "high temperature season" is getting longer and longer, and the temperature is getting hotter and hotter, forming an "urban high temperature thermal environment". The urban thermal environment directly affects urban people, outdoor workers, the poor, the elderly and children, etc.; today's energy Electricity prices have soared. In order to save electricity bills, some people do not use air conditioning systems to cool down. As a result, many people suffer direct thermal injuries and health damage due to high temperatures. The average daily temperature is as high as 33 degrees Celsius, causing the mortality rate for those over 65 years old to be 15% higher than usual. In severe cases, urban outdoor temperatures are also rising year by year, and the high temperature sometimes exceeds the normal human body temperature of 37°C. (Taiwan Journal of Public Health, 2011).
Taiwan's National Forest Recreation Areas are located in a forest-covered environment and are distributed throughout Taipei, Central, South and East Districts. The altitude distribution of forest recreation areas ranges from 150 to 3,880m. Each National Forest Recreation Area has different attributes and special features. In addition to the natural environment landscape and forest recreation area, you can experience the natural environment and environmental phytoncides, etc., and the comfortable environment of the forest environment can also allow urban residents to stay away from the urban thermal environment during the "high temperature season".
Taiwan’s forest coverage rate is 60.7%, as shown in the Forestry Administration’s Fourth Forest Resources Survey Report, which is twice as high as the global average of 30.3%. Since 1965, the Forestry Administration of the Ministry of Agriculture has begun conducting surveys of all Taiwan’s national forest recreation areas. Planning and construction, there are currently 19 recreational areas, which will provide recreation for more than 4 million people in 2021 (Tourism Administration of the Ministry of Transportation and Communications, 2021).
This paper will analyze and explore how to visit the National Forest Recreation Area through tourism during the urban thermal environment season to avoid the physiological thermal discomfort of the human body caused by the urban thermal environment, and alleviate it through the comfortable environment of the National Forest Recreation Area through tourism; The research scope covers the temperature differences between the national forest recreation areas in the north, central, south and east divisions and the cities in the divisions, and then analyzes the distance between the national forest recreation areas and the cities and the cooling benefits, and provides cooling benefit information when the "high temperature season" comes. Provide the public with cooling guidance.
