广州帽峰山森林公园的“冷岛”效应分析

对帽峰山森林公园和广州市区2004年的月平均气温、月平均最高气温和月平均最低气温进行了统计,进而对帽峰山森林公园的"冷岛"效应进行了分析。结果表明:帽峰山森林公园月平均温度比广州市区月平均温度低2.2℃,森林公园"冷岛"效应显著;森林公园"冷岛"效应月际变化明显,5月到11月雨季的"冷岛"效应较强,而12月到翌年4月旱季"冷岛"效应较弱;森林公园"冷岛"效应日变化呈现昼弱夜强,其季节性也很强,秋冬季节夜间"冷岛"效应要明显的高于白天的效应,而春夏季节两者"冷岛"效应差别缓和。  

Micro-climate in Forest Park of Maofeng Mountains in Guangzhou

Micro-climate, comfortable degree and aero-anion concentration were tested in the Forest Park of Maofeng Mountain, Guangzhou, China. The results showed that the mean annual air temperature reduced by 2.2℃, annual relative humidity increased 10.4%, wind velocity reduced 0.4 m/s, and annual comfortable tourism period increased 32 days in the park by comparison to city center of Guangzhou. And the ultraviolet radiation index approached 0 and aero-anion concentration was above 900 ions/ cm3 in the forest park by measurement. It was suggested that the park has the advantages of long tourist time, abundant landscapes,high aero-anion concentration and great potential of tourism exploration in this paper.
