摘要：以无锡市惠山森林公园毛竹林和青山公园毛竹林为研究对象,对其林内和林缘的小气候日变化情况进行了定量化研究。结果表明:1)惠山森林公园与青山公园的相对湿度日变化皆呈先减后增趋势,均在13:00达到极值。林内相对湿度分别为67.6%、65.6%,林缘相对湿度分别为61.8%、63.4%;温度和综合舒适指数日变化皆呈先增后减趋势,也均在13:00达到极值,林内温度分别为28.2℃、27.5℃,林缘分别为29.8℃、28.9℃;林内综合舒适指数分别3.5、3.2,林缘综合舒适指数分别4.8、4.1。2)08:00～17:00林内人体舒适度高于林缘,其他时刻人体舒适度低于林缘。3)与密度较大的惠山森林公园竹林相比,青山公园竹林综合舒适指数降低了0.1～0.7,平均值为0.3,即密度较小的青山公园竹林调节城市小气候的功能最佳,为秋初时节人们户外活动提供了一个良好的选择。
The moso bamboo forests of Huishan Forest Park and Qingshan Park in Wuxi were selected to study diurnal variations in microclimate factors of the forests and their edges. The results showed that the diurnal variations in relative humidity of Huishan Forest Park and Qingshan Park both decreased first and then increased, reached extrema at 13：00. The relative humidity within the moso bamboo forests were relatively 67.6%, 65.6%, and their values of the edges were relatively 61.8%, 63.4% ; air temperature and comprehensive comfort index at first increased and then decreased, and all reached extrema at 13：00, the air temperature within the moso bamboo forests were relatively 28.2℃, 27.5℃, and values of the edges were relatively 29.8℃, 28.9% ; the comprehensive comfort index within the moso bamboo forests were relatively 3.5, 3.2, and the values of their edges were relatively 4, 8, 4.1. From 08：00 to 17：00 the human comfort degrees within the moso bamboo forests were higher than that of their edges, and were lower than that of their edges at other times. Compared with the moso bamboo forests of Huishan Forest Park with the higher density, the comprehensive comfort index of Qingshan Park reduced to 0.1 - 0.7, with the mean value of 0.3. It concluded that the moso bamboo forests of Qingshan Park with the lower density had better performances in conditioning urban microclimate and be an excellent place for outdoor activities in early autumn.
