亚热带森林旅游区夏季舒适温度的持续时间

Study on duration of comfortable temperature in forest tourist areas in subtropical zone

1984～2000年,在亚热带地区选择8处森林旅游区进行了小气候对比观测。根据逐时气温和空气相对湿度观测值,比较了森林旅游区内外、林分内外及不同海拔高处的舒适温度持续时间。结果表明:由于地形和森林的共同作用,森林旅游区令人感觉舒适的时间为14～24h,感觉闷热的时间0～10h,感觉极不舒适无法忍受的时间为0;而邻近乡镇、中小城市同期感觉舒适的时间仅0～11h,感觉闷热的时间10～24h,感觉极不舒适、无法忍受的时间长达5～9h;在一定高度内,由于海拔的升高,令人感觉舒适的时间由12h增加到24h,令人感觉闷热的时间则从12h减少到0。这一结果说明夏季酷热难熬的亚热带地区,林区和山区是避暑消夏、休闲度假的好去处。

From 1984 to 2000,comparative observation of small climates of 8 forest tourist spots in sub-tropical zones was conducted.According to air temperature and relative air humidity observed every hour,the durations of comfortable air temperatures inside and outside of the forest and the forest tourist spots at different altitudes are compared.The results show that in the forest tourist spots,the duration that people feel comfortalbe temperature is 14～24 h,that feel sultry is 0～10 h and that feel uncomfortalbe is 0 h.While in the neigboring towns,medium and small cities,the duration that people feel comfortable is only 0～11 h,that feel sultry is 10～24 h and that feel uncomfortalbe is 5～9 h.Within a certain range of altitudes,with the increase in altutude,the duration that people feel comfortable increases to 24 h from 12 h,that feel sultry decreases to 0 h and 12 h.It shows that in the sub-tropical zone with hot summer,forest and mountain areas are good places for passing the summer leisurely.[Ch,8 tab.5 ref.]
