摘　　要：以济南南部山区4种典型游憩林(侧柏纯林、侧柏黄栌混交林、刺槐纯林、经济林)为研究对象,调查分析了游憩林调节小气候和人体舒适度的效应。结果表明:在炎热的夏季,4种游憩林均具有显著的降温、增湿及降低风速的作用,能明显改善人体舒适度。不同游憩林调节小气候的作用存在差异,与对照相比,侧柏纯林、侧柏黄栌混交林、刺槐纯林、经济林分别日均降温2.10、2.75、2.15、0.67℃;增湿5.35%、8.0%、6.04%、2.92%;降低风速51.0%、66.4%、67.4%、37.0%。从人体舒适度来看,游憩林林内很舒适的时间延长了1 6 h;8:00-10:00和17:00-18:00达很舒适标准,最适合进入林地活动;体感舒适程度为侧柏黄栌混交林>侧柏纯林>刺槐纯林>经济林。侧柏黄栌混交林调节小气候和改善人体舒适度的作用最大,是夏季人们户外活动的首选之地。Based on the field observation data of microclimate factors in summer, the microclimate and human com- fort effects of four typical recreational forests （Pinus tabulaeformis forest, Pinus tabulaeformis-Cotintas coggygria mixed forest, Robinia pseudoacacia forest, and economic forest） were analyzed in southern mountain area of Ji＇ nan. The results indicated that the recreational forests had significant effects on lowering the air temperature, increasing relative humidity, descending wind speed and enhancing human comfort level in summer. It showed definite differ- ences in microclimate effects for different types of recreational forests. Compared with the contrast, the P. tabulae- formis forest, P. tabulaeformis-C, coggygria mixed forests, R. pseudoacacia forest and economic forest can lower the air temperature by 2.1, 2.75, 2.15, and 0.67℃ ; increase the humidity by 5.35% , 8.0% , 6. 04% , and 2. 92% and reduce the wind speed by 51.0% , 66.4% , 67.4% , and 37.0%. Recreational forests significantly prolonged the comfort by one to six hours; 8：00 to 10：00 and 17：00 to 18：00 were the most suitable time for outdoor activities which reached very comfort s gygria mixed mixed forests forest 〉 Pinus tabulaeformis is the best choice for outdoor comfort level in summer. tage. Human comfort level was in the order of： P. tabulaeformis-C, cog- forest 〉 R. pseudoacacia Jforest 〉 economic forest. It is concluded that activities which has the best effects on adjusting microclimate and human
