| 摘要: |
| 在暑期高温时对广州白云山国家级风景名胜区海南蒲桃（Syzygium cumini）＋阴香（Cinnamomum burmannii）林带的降温增湿效应进行了观测，结果表明：距离林带2 m处与距离林带16 m处相比，昼间平均光照强度低21 247 lx，昼间平均气温低1.8 ℃，昼间平均空气相对湿度大4.5%。随着与林带水平距离的增大，气温和空气相对湿度的起伏变化增大，海南蒲桃＋阴香林带不仅能有效减小太阳光照强度，而且表现出明显的降温增湿效应。 |

| Abstract: |
| The effect of decreasing temperature and increasing humidity of Syzygium cumini+ Cinnamomum burmannii belt at the Baiyun Mountain National Scenic Area, Guangzhou was observed in summer holiday, the results were: the average daytime light intensity of the plot that was 2 meters long from the S.cumini belt was 21 247 lx lower than the one of the plot that was 16 meters long from the S.cumini belt; the average daytime air temperature of the plot that was 2 meters long from the S.cumini belt was 1.8 ℃ lower than the one of the plot that was 16 meters long from the S.cumini belt; the average daytime air relative humidity of the plot that was 2 meters long from the S.cumini belt was 4.5% higher than the one of the plot that was 16 meters long from the S.cumini belt. It proves that the S.cumini belt not only can decrease the solar light intensity, but also has the effect of decreasing air temperature and increasing humidity. |
