校园绿地小气候是城市生态环境效益评价的重要内容之一,是广大师生员工学习、工作和生活娱乐的重要场所。为了探明校园不同绿地类型的小气候特征及其对人体舒适度的影响,在广西大学校园内选择密林(A)、疏林(B)和草坪(C)3种植被类型分别建立固定样地,对主要气象要素进行同步观测研究。结果表明:(1)A、B和C日平均太阳辐射能依次为11.7w/m2、39.5 w/m2和177.3 w/m2,其中密林内仅占草坪的6.6%。(2)A、B和C日平均气温依次为24.9℃、25.2℃和25.6℃,其中密林内比草坪低0.7℃。(3)A、B和C日平均地面温度依次为23.8℃、25.2℃和27.9℃,其中密林内比草坪低4.1℃。(4)A、B和C日平均相对湿度依次为91%、89%和88%,其中密林内比草坪高3%(RH)。(5)A、B和C日平均温湿指数依次为24.4、24.5和24.8,其中密林内比草坪低0.4。研究结果初步说明,校园内密林型在白天对太阳辐射的削减、降温、增湿以及对人体舒适作用明显。
校園綠地小氣候是城市生態環境效益評價的重要內容之一,是廣大師生員工學習、工作和生活娛樂的重要場所。為瞭探明校園不同綠地類型的小氣候特徵及其對人體舒適度的影響,在廣西大學校園內選擇密林(A)、疏林(B)和草坪(C)3種植被類型分彆建立固定樣地,對主要氣象要素進行同步觀測研究。結果錶明:(1)A、B和C日平均太暘輻射能依次為11.7w/m2、39.5 w/m2和177.3 w/m2,其中密林內僅佔草坪的6.6%。(2)A、B和C日平均氣溫依次為24.9℃、25.2℃和25.6℃,其中密林內比草坪低0.7℃。(3)A、B和C日平均地麵溫度依次為23.8℃、25.2℃和27.9℃,其中密林內比草坪低4.1℃。(4)A、B和C日平均相對濕度依次為91%、89%和88%,其中密林內比草坪高3%(RH)。(5)A、B和C日平均溫濕指數依次為24.4、24.5和24.8,其中密林內比草坪低0.4。研究結果初步說明,校園內密林型在白天對太暘輻射的削減、降溫、增濕以及對人體舒適作用明顯。

The campus green space microclimate is one of the important contents of evaluation of city ecological environmental benefits and it is an important environment for students and college stuff to study,work and perform recreation. In order to explore different micro-climate characteristics of campus green space types and its effects on human comfort,choose the forest on the campus of the Guangxi Uni-versity(A),sparse forest(B)and lawn(C)3 vegetation plots which were established to observe the main meteorological elements syn-chronously . The observation shows that: (1)A,B and C daily average solar radiation were 11.7w/m2,39.5 w/m2 and 177.3 w/m2,which accounted for 6.6%in the forest lawn. (2)A,average temperature of B and C were 24.9℃,25.2℃and 25.6℃,which is 0.7℃lower than the dense forest lawn. (3)A,B and C daily average ground temperature were 23.8℃,25.2℃and 27.9℃,which is 4.1℃lower than the dense forest lawn. (4)A,B and C daily average relative humidity were 91%,89 and 88%,which is 3%higher than the lawn (RH). (5)A,B and C daily average temperature humidity index were 24.4,24.5 and 24.8,which is 0.4 lower than the forest lawn. Re-search result reaches a abecedarian conclusion that the forest type does have a huge improvement in weakening radiation of the sun in the daytime ,cooling,humidifying as well as human comfort.
